Wie der C++-Programmierer bei der Analyse großer Datenmengen helfen kann

Die Programmiersprache C wurde von Dennis Ritchie in den Bell Labs in einer Zeit (1969-1973) entwickelt, als jeder CPU-Zyklus und jeder Byte Speicher sehr teuer war. Aus diesem Grund wurde C (und später C++) so konzipiert, dass die maximale Leistung der Hardware mit der Sprachkomplexität erzielt werden konnte. Derzeit ist der C++ Programmierer besonders begehrt auf dem Arbeitsmarkt, für ganz bestimmte Abläufe, die wir später genauer beschreiben werden.

Warum sollten Sie einen C++ Entwickler mieten, wenn es um große Daten geht?

C++ ermöglicht, als Sprache auf einem niedrigen Level, eine Feinabstimmung der Leistung der Anwendung in einer Weise, die bei der Verwendung von Sprachen auf einem hohen Level nicht möglich ist. Warum sollten Sie einen C++ Entwickler mieten? C++ bietet den Entwicklern eine viel bessere Kontrolle über den Systemspeicher und die Ressourcen, als die der C Programmierer oder Anderer.

C++ ist die einzige Sprache, in der man Daten mit mehr als 1 GB pro Sekunde knacken, die prädiktive Analyse in Echtzeit neu trainieren und anwenden und vierstellige QPS einer REST-ful API in der Produktion bedienen kann, während die [eventuelle] Konsistenz des Aufzeichnungssystems ständig erhalten bleibt. Auf einem einzigen Server, natürlich aus Gründen der Zuverlässigkeit dupliziert, aber das, ohne in Repliken, Sharding und das Auffüllen und Wiederholen von persistenten Nachrichtenwarteschlangen investieren zu. Für ein groß angelegtes Werbesystem, dynamischen Lastausgleich oder eine hocheffiziente adaptive Caching-Schicht ist C++ die klügste Wahl.

Die allgemeine Vorstellung ist, dass R und Python schneller sind, aber das ist weit von der Wahrheit entfernt. Ein gut optimierter C++-Code könnte hundertmal schneller laufen, als das gleiche Stück Code, das in Python oder R geschrieben wurde. Die einzige Herausforderung bei C++ ist die Menge an Arbeit, die Sie bewältigen müssen, um die fertigen Funktionen zum Laufen zu bringen. Sie müssen wissen, wie man Zeiger verteilt und verwaltet – was ehrlich gesagt ein wenig kompliziert sein kann. Die C# Programmierer Ausbildung ist aus diesem Grunde z.Z. sehr begehrt.

R und Python

Akademiker und Statistiker haben R über zwei Jahrzehnte entwickelt. R verfügt nun über eines der reichsten Ökosysteme, um Datenanalysen durchzuführen. Es sind etwa 12000 Pakete in CRAN (Open-Source-Repository) verfügbar. Es ist möglich, eine Bibliothek zu finden, für was auch immer für eine Analyse Sie durchführen möchten. Die reiche Vielfalt der Bibliothek macht R zur ersten Wahl für statistische Analysen, insbesondere für spezialisierte analytische Arbeiten.

Python kann so ziemlich die gleichen Aufgaben wie R erledigen: Data Wrangling, Engineering, Feature Selection Web Scrapping, App und so weiter. Python ist ein Werkzeug, um maschinelles Lernen in großem Maßstab einzusetzen und zu implementieren. Python-Codes sind einfacher zu warten und robuster als R. Vor Jahren hatte Python nicht viele Bibliotheken für Datenanalyse und maschinelles Lernen. In letzter Zeit holt Python auf und bietet eine hochmoderne API für maschinelles Lernen oder künstliche Intelligenz. Der größte Teil der datenwissenschaftlichen Arbeit kann mit fünf Python-Bibliotheken erledigt werden: Numpy, Pandas, Scipy, Scikit-Learning und Seaborn.

Aber das Wissen, mit Zeigern zu arbeiten oder den Code in C++ zu verwalten, ist mit einem hohen Preis verbunden. Aus diesem Grunde werden C++ Programmierer gesucht, für die Bewältigung von großen Datenpaketen. Ein tiefer Einblick in das Innenleben der Anwendung ermöglicht es ihnen, die Anwendung im Falle von Fehlern besser zu debuggen und sogar Funktionen zu erstellen, die eine Kontrolle des Systems auf Mikroebene erfordern. Schauen Sie sich doch nach C# Entwickler in Berlin um, denn sie haben einen besonders guten Ruf unter den neuen Entwicklern.

Das Erlernen der Programmierung ist eine wesentliche Fähigkeit im Arsenal der Analysten von Big Data. Analysten müssen kodieren, um numerische und statistische Analysen mit großen Datensätzen durchzuführen. Einige der Sprachen, in deren Erlernen auch die C Entwickler Zeit und Geld investieren sollten, sind unter anderem Python, R, Java und C++. Je mehr sie wissen, desto besser – Programmierer sollten immer daran denken, dass sie nicht nur eine einzelne Sprache lernen sollten. C für Java Programmierer sollte ein MUSS sein.

Wo wird das C++ Programmieren eingesetzt?

Die Programmiersprache C++ ist eine etablierte Sprache mit einem großen Satz von Bibliotheken und Tools, die bereit ist, große Datenanwendungen und verteilte Systeme zu betreiben. In den meisten Fällen wird C++ zum Schreiben von Frameworks und Paketen für große Daten verwendet. Diese Programmiersprache bietet auch eine Reihe von Bibliotheken, die beim Schreiben von Algorithmen für das tiefe Lernen helfen. Mit ausreichenden C++-Kenntnissen ist es möglich, praktisch unbegrenzte Funktionen auszuführen. Dennoch ist C++ nicht die Sprache, die man leicht erlernen kann, da man die über 1000 Seiten Spezifikation und fast 100 Schlüsselwörter beherrschen muss.

Die Verwendung von C++ ermöglicht die prozedurale Programmierung für intensive Funktionen der CPU und die Kontrolle über die Hardware, und diese Sprache ist sehr schnell, weshalb sie bei der Entwicklung verschiedener Spiele oder in Spielmaschinen weit verbreitet ist.

C++ bietet viele Funktionen, die anderen Sprachen fehlen. Darüber hinaus bietet die Sprache auch Zugang zu umfangreichen Vorlagen, die es Ihnen ermöglichen, generische Codes zu schreiben. Als betroffenes Unternehmen sollten Sie sich deshalb tatsächlich überlegen, einen C++ Programmierer zu suchen oder in einen Kurs von C++ für Ihren C Programmierer zu investieren. Am Ende lohnen sich bestimmt diese Kosten.

Und vergessen Sie nicht: C++ ist die einzige Sprache, die in der Lage ist, 1 GB+ Daten in weniger als einer Sekunde zu verarbeiten. Darüber hinaus können Sie Ihr Modell neu trainieren und prädiktive Analysen in Echtzeit und sogar die Konsistenz der Systemaufzeichnung anwenden. Diese Gründe machen C++ zu einer bevorzugten Wahl für Sie, wenn Sie einen Datenwissenschaftler für Ihr Unternehmen suchen.

Beispiele für die Verwendung von C++

Die Verwendung von C++ zur Entwicklung von Anwendungen und vielen produktbasierten Programmen, die in dieser Sprache entwickelt wurden, hat mehrere Vorteile, die nur auf ihren Eigenschaften und ihrer Sicherheit beruhen. Unten finden Sie eine Liste der häufigsten Anwendungen von C++.

  • Google-Anwendungen – Einige der Google-Anwendungen sind auch in C++ geschrieben, darunter das Google-Dateisystem und der Google-Chromium-Browser sowie MapReduce für die Verarbeitung großer Clusterdaten. Die Open-Source-Gemeinschaft von Google hat über 2000 Projekte, von denen viele in den Programmiersprachen C oder C++ geschrieben und bei GitHub frei verfügbar sind.
  • Mozilla Firefox und Thunderbird – Der Mozilla-Internetbrowser Firefox und der E-Mail-Client Thunderbird sind beide in der Programmiersprache C++ geschrieben, und sie sind ebenfalls Open-Source-Projekte. Der C++-Quellcode dieser Anwendungen ist in den MDN-Webdokumenten zu finden.
  • Adobe-Systeme – Die meisten der wichtigsten Anwendungen von Adobe-Systemen werden in der Programmiersprache C++ entwickelt. Zu diesen Anwendungen gehören Adobe Photoshop und Image Ready, Illustrator und Adobe Premier. Sie haben in der Vergangenheit eine Menge Open-Source-Codes veröffentlicht, immer in C++, und ihre Entwickler waren in der C++-Community aktiv.
  • 12D-Lösungen – 12D Solutions Pty Ltd ist ein australischer Softwareentwickler, der sich auf Anwendungen im Bereich Bauwesen und Vermessung spezialisiert hat. Computer Aided Design-System für Vermessung, Bauwesen und mehr. Zu den Kunden von 12D Solutions gehören Umweltberater, Berater für Bau- und Wasserbau, lokale, staatliche und nationale Regierungsabteilungen und -behörden, Vermessungsingenieure, Forschungsinstitute, Bauunternehmen und Bergbau-Berater.
  • In C/C++ geschriebene Betriebssysteme

Apple – Betriebssystem OS XApple – Betriebssystem OS X

Einige Teile von Apple OS X sind in der Programmiersprache C++ geschrieben. Auch einige Anwendungen für den iPod sind in C++ geschrieben.

Microsoft-BetriebssystemeMicrosoft-Betriebssysteme

Der Großteil der Software wird buchstäblich mit verschiedenen Varianten von Visual C++ oder einfach C++ entwickelt. Die meisten der großen Anwendungen wie Windows 95, 98, Me, 200 und XP sind ebenfalls in C++ geschrieben. Auch Microsoft Office, Internet Explorer und Visual Studio sind in Visual C++ geschrieben.

  • Betriebssystem Symbian – Auch Symbian OS wird mit C++ entwickelt. Dies war eines der am weitesten verbreiteten Betriebssysteme für Mobiltelefone.

Die Einstellung eines C- oder C++-Entwicklers kann eine gute Investition in Ihr Projekt-Upgrade sein

Normalerweise benötigen C- und C++-Anwendungen weniger Strom, Speicher und Platz als die Sprachen der virtuellen Maschinen auf hoher Ebene. Dies trägt dazu bei, den Kapitalaufwand, die Betriebskosten und sogar die Kosten für die Serverfarm zu reduzieren. Hier zeigt sich, dass C++ die Gesamtentwicklungskosten erheblich reduziert.

Trotz der Tatsache, dass wir eine Reihe von Tools und Frameworks nur für die Verwaltung großer Daten und die Arbeit an der Datenwissenschaft haben, ist es wichtig zu beachten, dass auf all diesen modernen Frameworks eine Schicht einer niedrigen Programmiersprache – wie C++ – aufgesetzt ist. Die Niedrigsprachen sind für die tatsächliche Ausführung des dem Framework zugeführten Hochsprachencodes verantwortlich. Es ist also ratsam in ein C-Entwickler-Gehalt zu investieren.

Der Grund dafür, dass C++ ein so unverzichtbares Werkzeug ist, liegt darin, dass es nicht nur einfach, sondern auch extrem leistungsfähig ist und zu den schnellsten Sprachen auf dem Markt gehört. Darüber hinaus verfügt ein gut geschriebenes Programm in C++ über ein komplexes Wissen und Verständnis der Architektur der Maschine, sowie der Speicherzugriffsmuster und kann schneller laufen als andere Programme. Es wird Ihrem Unternehmen Zeit- und Stromkosten sparen.

Zum Abschluss eine Grafik, die Sie als Unternehmer interessieren wird und die das Verhältnis von der Performance and der Sicherheit diverser Sprachen darstellt:

Aus diesen und weiteren Gründen neigen viele Unternehmensentwickler und Datenwissenschaftler mit massiven Anforderungen an Skalierbarkeit und Leistung zu dem guten alten C++. Viele Organisationen, die Python oder andere Hochsprachen für die Datenanalyse und Erkundungsaufgaben verwenden, verlassen sich auf C++, um Programme zu entwickeln, die diese Daten an die Kunden weiterleiten – in Echtzeit.

Multi-touch attribution: A data-driven approach

This is the first article of article series Getting started with the top eCommerce use cases.

What is Multi-touch attribution?

Customers shopping behavior has changed drastically when it comes to online shopping, as nowadays, customer likes to do a thorough market research about a product before making a purchase. This makes it really hard for marketers to correctly determine the contribution for each marketing channel to which a customer was exposed to. The path a customer takes from his first search to the purchase is known as a Customer Journey and this path consists of multiple marketing channels or touchpoints. Therefore, it is highly important to distribute the budget between these channels to maximize return. This problem is known as multi-touch attribution problem and the right attribution model helps to steer the marketing budget efficiently. Multi-touch attribution problem is well known among marketers. You might be thinking that if this is a well known problem then there must be an algorithm out there to deal with this. Well, there are some traditional models  but every model has its own limitation which will be discussed in the next section.

Traditional attribution models

Most of the eCommerce companies have a performance marketing department to make sure that the marketing budget is spent in an agile way. There are multiple heuristics attribution models pre-existing in google analytics however there are several issues with each one of them. These models are:

First touch attribution model

100% credit is given to the first channel as it is considered that the first marketing channel was responsible for the purchase.

Figure 1: First touch attribution model

Last touch attribution model

100% credit is given to the last channel as it is considered that the first marketing channel was responsible for the purchase.

Figure 2: Last touch attribution model

Linear-touch attribution model

In this attribution model, equal credit is given to all the marketing channels present in customer journey as it is considered that each channel is equally responsible for the purchase.

Figure 3: Linear attribution model

U-shaped or Bath tub attribution model

This is most common in eCommerce companies, this model assigns 40% to first and last touch and 20% is equally distributed among the rest.

Figure 4: Bathtub or U-shape attribution model

Data driven attribution models

Traditional attribution models follows somewhat a naive approach to assign credit to one or all the marketing channels involved. As it is not so easy for all the companies to take one of these models and implement it. There are a lot of challenges that comes with multi-touch attribution problem like customer journey duration, overestimation of branded channels, vouchers and cross-platform issue, etc.

Switching from traditional models to data-driven models gives us more flexibility and more insights as the major part here is defining some rules to prepare the data that fits your business. These rules can be defined by performing an ad hoc analysis of customer journeys. In the next section, I will discuss about Markov chain concept as an attribution model.

Markov chains

Markov chains concepts revolves around probability. For attribution problem, every customer journey can be seen as a chain(set of marketing channels) which will compute a markov graph as illustrated in figure 5. Every channel here is represented as a vertex and the edges represent the probability of hopping from one channel to another. There will be an another detailed article, explaining the concept behind different data-driven attribution models and how to apply them.

Figure 5: Markov chain example

Challenges during the Implementation

Transitioning from a traditional attribution models to a data-driven one, may sound exciting but the implementation is rather challenging as there are several issues which can not be resolved just by changing the type of model. Before its implementation, the marketers should perform a customer journey analysis to gain some insights about their customers and try to find out/perform:

  1. Length of customer journey.
  2. On an average how many branded and non branded channels (distinct and non-distinct) in a typical customer journey?
  3. Identify most upper funnel and lower funnel channels.
  4. Voucher analysis: within branded and non-branded channels.

When you are done with the analysis and able to answer all of the above questions, the next step would be to define some rules in order to handle the user data according to your business needs. Some of the issues during the implementation are discussed below along with their solution.

Customer journey duration

Assuming that you are a retailer, let’s try to understand this issue with an example. In May 2016, your company started a Fb advertising campaign for a particular product category which “attracted” a lot of customers including Chris. He saw your Fb ad while working in the office and clicked on it, which took him to your website. As soon as he registered on your website, his boss called him (probably because he was on Fb while working), he closed everything and went for the meeting. After coming back, he started working and completely forgot about your ad or products. After a few days, he received an email with some offers of your products which also he ignored until he saw an ad again on TV in Jan 2019 (after 3 years). At this moment, he started doing his research about your products and finally bought one of your products from some Instagram campaign. It took Chris almost 3 years to make his first purchase.

Figure 6: Chris journey

Now, take a minute and think, if you analyse the entire journey of customers like Chris, you would realize that you are still assigning some of the credit to the touchpoints that happened 3 years ago. This can be solved by using an attribution window. Figure 6 illustrates that 83% of the customers are making a purchase within 30 days which means the attribution window here could be 30 days. In simple words, it is safe to remove the touchpoints that happens after 30 days of purchase. This parameter can also be changed to 45 days or 60 days, depending on the use case.

Figure 7: Length of customer journey

Removal of direct marketing channel

A well known issue that every marketing analyst is aware of is, customers who are already aware of the brand usually comes to the website directly. This leads to overestimation of direct channel and branded channels start getting more credit. In this case, you can set a threshold (say 7 days) and remove these branded channels from customer journey.

Figure 8: Removal of branded channels

Cross platform problem

If some of your customers are using different devices to explore your products and you are not able to track them then it will make retargeting really difficult. In a perfect world these customers belong to same journey and if these can’t be combined then, except one, other paths would be considered as “non-converting path”. For attribution problem device could be thought of as a touchpoint to include in the path but to be able to track these customers across all devices would still be challenging. A brief introduction to deterministic and probabilistic ways of cross device tracking can be found here.

Figure 9: Cross platform clash

How to account for Vouchers?

To better account for vouchers, it can be added as a ‘dummy’ touchpoint of the type of voucher (CRM,Social media, Affiliate or Pricing etc.) used. In our case, we tried to add these vouchers as first touchpoint and also as a last touchpoint but no significant difference was found. Also, if the marketing channel of which the voucher was used was already in the path, the dummy touchpoint was not added.

Figure 10: Addition of Voucher as a touchpoint

Let me know in comments if you would like to add something or if you have a different perspective about this use case.

4 Industries Likely to Be Further Impacted by Data and Analytics in 2020

The possibilities for collecting and analyzing data have skyrocketed in recent years. Company leaders no longer must rely primarily on guesswork when making decisions. They can look at the hard statistics to get verification before making a choice.

Here are four industries likely to notice continuing positive benefits while using data and analytics in 2020.

  1. Transportation

If the transportation sector suffers from problems like late arrivals or buses and trains never showing up, people complain. Many use transportation options to reach work or school, and use long-term solutions like planes to visit relatives or enjoy vacations.

Data analysis helps transportation authorities learn about things such as ridership numbers, the most efficient routes and more. Digging into data can also help professionals in the sector verify when recent changes pay off.

For example, New York City recently enacted a plan called the 14th Street Busway. It stops cars from traveling on 14th Street for more than a couple of blocks from 6 a.m. to 10 p.m. every day. One of the reasons for making the change was to facilitate the buses that carry passengers along 14th Street. Data confirms the Busway did indeed encourage people to use the bus. Ridership jumped 24% overall, and by 20% during the morning rush hour.

Data analysis could also streamline air travel. A new solution built with artificial intelligence can reportedly make flights more on time and reduce fuel consumption by improving traffic flow in the terminals. The system also crunches numbers to warn people about long lines in an airport. Then, some passengers might make schedule adjustments to avoid those backups.

These examples prove why it’s smart for transportation professionals to continually see what the data shows. Becoming more aware of what’s happening, where problems exist and how people respond to different transit options could lead to better decision-making.

  1. Agriculture

People in the agriculture industry face numerous challenges, such as climate change and the need to produce food for a growing global population. There’s no single, magic fix for these challenges, but data analytics could help.

For example, MIT researchers are using data to track the effects of interventions on underperforming African farms. The outcome could make it easier for farmers to prove that new, high-tech equipment will help them succeed, which could be useful when applying for loans.

Elsewhere, scientists developed a robot called the TerraSentia that can collect information about a variety of crop traits, such as the height and biomass. The machine then transfers that data to a farmer’s laptop or computer. The robot’s developers say their creation could help farmers figure out which kinds of crops would give the best yields in specific locations, and that the TerraSentia will do it much faster than humans.

Applying data analysis to agriculture helps farmers remove much of the guesswork from what they do. Data can help them predict the outcome of a growing season, target a pest or crop disease problem and more. For these reasons and others, data analysis should remain prominent in agriculture for the foreseeable future.

  1. Energy 

Statistics indicate global energy demand will increase by at least 30% over the next two decades. Many energy industry companies have turned to advanced data analysis technologies to prepare for that need. Some solutions examine rocks to improve the detection of oil wells, while others seek to maximize production over the lifetime of an oilfield.

Data collection in the energy sector is not new, but there’s been a long-established habit of only using a small amount of the overall data collected. That’s now changing as professionals are more frequently collecting new data, plus converting information from years ago into usable data.

Strategic data analysis could also be a good fit for renewable energy efforts. A better understanding of weather forecasts could help energy professionals pinpoint how much a solar panel or farm could contribute to the electrical grid on a given day.

Data analysis helps achieve that goal. For example, some solutions can predict the weather up to a month in advance. Then, it’s possible to increase renewable power generation by up to 10%.

  1. Construction

Construction projects can be costly and time-consuming, although the results are often impressive. Construction professionals must work with a vast amount of data as they meet customers’ needs. Site plans, scheduling specifics, weather information and regulatory documents all help define how the work progresses and whether everything stays under budget.

Construction firms increasingly use big data analysis software to pull all the information into one place and make it easier to use. That data often streamlines customer communications and helps with meeting expectations. In one instance, a construction company depended on a real-time predictive modeling solution and combined it with in-house estimation software.

The outcome enabled instantly showing a client how much a new addition would cost. Other companies that are starting to use big data in construction note that having the option substantially reduces their costs — especially during the planning phase before construction begins. Another company is working on a solution that can analyze job site photos and use them to spot injury risks.

Data Analysis Increases Success

The four industries mentioned here have already enjoyed success by investigating the potential data analysis offers. People should expect them to continue making gains through 2020.

Data Scientist: Rock the Tech World

It’s almost 2020! Are you a data Rockstar or a laggard?

IDC agrees to the fact that the global data, 33 zettabytes in 2018 is predicted to grow to 175 zettabytes by 2025. That’s like ten times bigger the amount of data seen in 2017.

Isn’t this an exciting analysis? 

Hold on! Are all the industries set for a digitally transformed future? 

A digital transformed future is an opportunity of historic proportions. The way data is consumed today changes the way we work, live, and play. Businesses across the globe are now using data to transform themselves to adapt to these changes, become agile, improve customer experience, and to introduce new business models. 

With the full dependency on online channels, connectivity with friends and family around the world has increased the consumption of data. Today, the entire economy is reliant on data. Without data, you’re lost. 

Leverage the benefits of the data era

At the outset, with not many big data industries to be found, we can still agree to the fact that the knowledge for data skills is still early for professionals in the big data realm.

  • Big data assisting the humanitarian aid 
    • Case study: During a disaster

Be it natural or conflict-driven – if the response is driven quickly, it minimizes problems that are predicted to happen. In such instances, big data could be of great help in helping improve the responses of the aid organizations. 

Data scientists can easily use analytics and algorithms to provide actionable insights that can be used during emergencies to identify patterns in the data that is generated by online connected devices or from other related sources. 

During a 2015 refugee crisis in Germany, the Sweden Migration Board saw 10,000 asylum seekers every week up from 2,500 asylum seekers they saw in a month. A critical situation where other organizations could have faced challenges in dealing with the problem. However, with the help of big data this agency could cope up with the challenges. The challenges were addressed by ensuring extra staff was hired and of securing housing started early. Big data was of aid to this agency, meaning since they were users of this the preprocessing technology for quite a long time, the predictions were given well ahead of time. 

Earlier the results were not easy to extract due to obstruction such as not finding the relevant data. However, now with the launch of open data initiatives, the process has become easy. 

  • Tapping into talents of data scientist 

The Defence Science and Technology Laboratory (Dstl) along with other government partners launched “The Data Science Challenge.” This is done to harness the skills of data science professionals, to check their capability of tackling real-world problems people face daily. 

The challenge is part of a wider program set out majorly in the Defence Innovation Initiative.

It is an open data science challenge that welcome entrants from all facets of background and specialization to demonstrate their skills. The challenge is to acknowledge that the best of minds need not necessarily be the ones that work for you. 

 

  • The challenge comprises of two competitions each offering an award of £40,000
  1. First competition – this analyzes the ability to analyze data that is in documents i.e. media reports. This helps the data scientist have a deeper understanding of a political situation like it occurs for those on the ground level and even for those assisting it from afar. 
  2. Second competition – the second test involves creating possible ways to detect and classify vehicles like buses, cars, and motorbikes easily from aerial imagery. A solution to be used for aiding the safe journey of vehicles going through conflict zones.  

What makes the data world significant?

In all aspects, the upshot of the paradigm shift is that data has become a critical influencer in businesses as well as our lives. Internet of things (IoT) and embedded devices are already pacing their way in boosting the big data world. 

Some great key findings based on research by IDC: –

  • 75% of the population that interacts with data is estimated to stay connected by 2025.
  • The number of embedded devices that can be found on driverless cars, manufacturing floors, and smart buildings is estimated to grow from less than one per person to more than four in the next decade. 
  • In 2025, the amount of real-time data created in the data sphere is estimated to be over 25% while IoT real-time data will be more than 95%. 

With the data science industry becoming the top-end of the pyramid, a certified data scientist plays an imperative role today. 

In recent times, it is seen that big data has emerged to be the célèbre in the tech industry, generating several job opportunities.

What do you consider yourself to be today? 

Defining a data scientist is tough and finding one is tougher!

 

The importance of being Data Scientist

Header-Image by Clint Adair on Unsplash.

The incredible results of Machine Learning and Artificial Intelligence, Deep Learning in particular, could give the impression that Data Scientist are like magician. Just think of it. Recognising faces of people, translating from one language to another, diagnosing diseases from images, computing which product should be shown for us next to buy and so on from numbers only. Numbers which existed for centuries. What a perfect illusion. But it is only an illusion, as Data Scientist existed as well for centuries. However, there is a difference between the one from today compared to the one from the past: evolution.

The main activity of Data Scientist is to work with information also called data. Records of data are as old as mankind, but only within the 16 century did it include also numeric forms — as numbers started to gain more and more ground developing their own symbols. Numerical data, from a given phenomenon — being an experiment or the counts of sheep sold by week over the year –, was from early on saved in tabular form. Such a way to record data is interlinked with the supposition that information can be extracted from it, that knowledge — in form of functions — is hidden and awaits to be discovered. Collecting data and determining the function best fitting them let scientist to new insight into the law of nature right away: Galileo’s velocity law, Kepler’s planetary law, Newton theory of gravity etc.

Such incredible results where not possible without the data. In the past, one was able to collect data only as a scientist, an academic. In many instances, one needed to perform the experiment by himself. Gathering data was tiresome and very time consuming. No sensor which automatically measures the temperature or humidity, no computer on which all the data are written with the corresponding time stamp and are immediately available to be analysed. No, everything was performed manually: from the collection of the data to the tiresome computation.

More then that. Just think of Michael Faraday and Hermann Hertz and there experiments. Such endeavour where what we will call today an one-man-show. Both of them developed parts of the needed physics and tools, detailed the needed experiment settings, conducting the experiment and collect the data and, finally, computing the results. The same is true for many other experiments of their time. In biology Charles Darwin makes its case regarding evolution from the data collected in his expeditions on board of the Beagle over a period of 5 years, or Gregor Mendel which carry out a study of pea regarding the inherence of traits. In physics Blaise Pascal used the barometer to determine the atmospheric pressure or in chemistry Antoine Lavoisier discovers from many reaction in closed container that the total mass does not change over time. In that age, one person was enough to perform everything and was the reason why the last part, of a data scientist, could not be thought of without the rest. It was inseparable from the rest of the phenomenon.

With the advance of technology, theory and experimental tools was a specialisation gradually inescapable. As the experiments grow more and more complex, the background and condition in which the experiments were performed grow more and more complex. Newton managed to make first observation on light with a simple prism, but observing the line and bands from the light of the sun more than a century and half later by Joseph von Fraunhofer was a different matter. The small improvements over the centuries culminated in experiments like CERN or the Human Genome Project which would be impossible to be carried out by one person alone. Not only was it necessary to assign a different person with special skills for a separate task or subtask, but entire teams. CERN employs today around 17 500 people. Only in such a line of specialisation can one concentrate only on one task alone. Thus, some will have just the knowledge about the theory, some just of the tools of the experiment, other just how to collect the data and, again, some other just how to analyse best the recorded data.

If there is a specialisation regarding every part of the experiment, what makes Data Scientist so special? It is impossible to validate a theory, deciding which market strategy is best without the work of the Data Scientist. It is the reason why one starts today recording data in the first place. Not only the size of the experiment has grown in the past centuries, but also the size of the data. Gauss manage to determine the orbit of Ceres with less than 20 measurements, whereas the new picture about the black hole took 5 petabytes of recorded data. To put this in perspective, 1.5 petabytes corresponds to 33 billion photos or 66.5 years of HD-TV videos. If one includes also the time to eat and sleep, than 5 petabytes would be enough for a life time.

For Faraday and Hertz, and all the other scientist of their time, the goal was to find some relationship in the scarce data they painstakingly recorded. Due to time limitations, no special skills could be developed regarding only the part of analysing data. Not only are Data Scientist better equipped as the scientist of the past in analysing data, but they managed to develop new methods like Deep Learning, which have no mathematical foundation yet in spate of their success. Data Scientist developed over the centuries to the seldom branch of science which bring together what the scientific specialisation was forced to split.

What was impossible to conceive in the 19 century, became more and more a reality at the end of the 20 century and developed to a stand alone discipline at the beginning of the 21 century. Such a development is not only natural, but also the ground for the development of A.I. in general. The mathematical tools needed for such an endeavour where already developed by the half of the 20 century in the period when computing power was scars. Although the mathematical methods were present for everyone, to understand them and learn how to apply them developed quite differently within every individual field in which Machine Learning/A.I. was applied. The way the same method would be applied by a physicist, a chemist, a biologist or an economist would differ so radical, that different words emerged which lead to different langues for similar algorithms. Even today, when Data Science has became a independent branch, two different Data Scientists from different application background could find it difficult to understand each other only from a language point of view. The moment they look at the methods and code the differences will slowly melt away.

Finding a universal language for Data Science is one of the next important steps in the development of A.I. Then it would be possible for a Data Scientist to successfully finish a project in industry, turn to a new one in physics, then biology and returning to industry without much need to learn special new languages in order to be able to perform each tasks. It would be possible to concentrate on that what a Data Scientist does best: find the best algorithm. In other words, a Data Scientist could resolve problems independent of the background the problem was stated.

This is the most important aspect that distinguish the Data Scientist. A mathematician is limited to solve problems in mathematics alone, a physicist is able to solve problems only in physics, a biologist problems only in biology. With a unique language regarding the methods and strategies to solve Machine Learning/A.I. problems, a Data Scientist can solve a problem independent of the field. Specialisation put different branches of science at drift from each other, but it is the evolution of the role of the Data Scientist to synthesize from all of them and find the quintessence in a language which transpire beyond all the field of science. The emerging language of Data Science is a new building block, a new mathematical language of nature.

Although such a perspective does not yet exists, the principal component of Machine Learning/A.I. already have such proprieties partially in form of data. Because predicting for example the numbers of eggs sold by a company or the numbers of patients which developed immune bacteria to a specific antibiotic in all hospital in a country can be performed by the same prediction method. The data do not carry any information about the entities which are being predicted. It does not matter anymore if the data are from Faraday’s experiment, CERN of Human Genome. The same data set and its corresponding prediction could stand literary for anything. Thus, the result of the prediction — what we would call for a human being intuition and/or estimation — would be independent of the domain, the area of knowledge it originated.

It also lies at the very heart of A.I., the dream of researcher to create self acting entities, that is machines with consciousness. This implies that the algorithms must be able to determine which task, model is relevant at a given moment. It would be to cumbersome to have a model for every task and and every field and then try to connect them all in one. The independence of scientific language, like of data, is thus a mandatory step. It also means that developing A.I. is not only connected to develop a new consciousness, but, and most important, to the development of our one.

Essential Tips To Know In Order To Get Hired As A Data Scientist

In today’s day and age, information is a significant asset of any company. Thanks to technology, companies receive loads of data on a daily basis. It takes time and skill to filter out and sift through all the information in order to determine which areas are useful for the company. This is where your job as a data scientist, also referred to as a data analyst, comes in.

If you’ve long been wanting to work as a data scientist, here are some tips you can follow:

  1. Know What A Data Scientist Really Does

When you wish to be hired as a data scientist, you have to know what the job entails. More than just the job title, you also have to be aware of the day-to-day operations in the workplace. Because data is overflowing, it’s the job of a data scientist to analyze data and use their technical skills to solve problems relating to the data presented. When there aren’t any problems found, they also strive to find possible problems.

As a data scientist, you get to enjoy numerous specializations in your job. Xcede data scientist jobs, for instance, have other responsibilities that can include working as a mathematician, and even as statistics and economics experts. To be hired as a data scientist, you must first be familiar with the ins and outs of the job.

  1. Know The Basic Qualifications

Before you even apply for entry-level data scientist jobs, you also have to be aware of its basic qualifications. If you’ve completed a bachelor’s degree or even a master’s degree in data science or data analysis, then you’re a likely candidate for the job.

But if you don’t have this degree, don’t be dismayed. There are still related courses that can land you the job. Some of these include having a background in Mathematics, Economics, Finance, and Statistics.

Additional basic academic qualifications that you need in order to be hired as a data scientist include:

  • Bachelor’s degree in any of the related fields as mentioned above
  • Master’s degree in any of the fields related to data, mathematics, statistics, and economics
  • At least one to two years of experience in a related field before fully applying as a data scientist
  1. Obtain Further Studies And Experience

While information is an asset that’s highly in-demand today, it doesn’t mean that you’re going to land a job right after your first interview. Especially if you’re a fresh graduate, it’s highly advised that you work in a job that’s related to the course you’ve just finished. In most cases, prior experience is needed before you can get a job in data science. For instance, if you’ve graduated from a Mathematics course, work in this field first.

A critical piece of advice you should remember is that the data science industry is a highly competitive one. While you can successfully find entry-level data science jobs, others might be looking for additional qualifications. In this case, grab the opportunity to further your knowledge and studies, whether that’s getting additional certifications, continuing your education to obtain a higher degree, or familiarizing yourself with the different software and skills needed for the job. Moreover, make it a point to attend training programs as well as seminars relating to data science. Doing this will increase your chances of getting hired.

  1. Know The Basic Skills Needed

More than just your educational attainment, employers are also looking for this basic set of skills:

  • Mathematical Capabilities: As a data scientist, you will be facing a lot of data and statistics, but not all of them will be relevant. In their raw form, it’s up to you to process and study the data deeper so these statistics can be arranged and translated into useful information.
  • Data Management and Manipulation: This means having basic knowledge on data management software in order to keep up with the times, as well as analyze, arrange, and interpret data in a more efficient and timely manner.
  • Programming: This is an integral part of data science. Hence, you must also possess the basic skills involving primary programming languages, such as Java and C++. This is necessary since data analysis tools that require knowledge in computer science and programming will be used to analyze and process the data that you’re presented with. This is where your expertise in programming can come in handy.

Possessing these skills can give you an edge over other applicants, especially if you’re familiar with the software a particular company is using.

Conclusion

Applying as a data scientist or data analyst is not entirely different from when you’re applying to other jobs. It may sound more technical, but the principles are still the same: you need to first understand your job description, responsibilities, and the basic skills and qualifications needed in order to be efficient in the workplace. You can also increase your chances of getting hired by enhancing your credentials and certifications through further studies. Take a masters’ degree, if necessary. These tips, along with patience and determination, can help kickstart your career as a data scientist.

Accelerate your AI Skills Today: A Million Dollar Job!

The skyrocketing salaries ($1m per year) of AI engineers is not a hype. It is the fact of current corporate world, where you will witness a shift that is inevitable.

We’ve already set our feet at the edge of the technological revolution. A revolution that is at the verge of altering the way we live and work. As the fact suggests, humanity has fundamentally developed human production in three revolutions, and we’re now entering the fourth revolution. In its scope, the fourth revolution projects a transformation that is unlike anything we humans have ever experienced.

  • The first revolution had the world transformed from rural to urban
  • the emergence of mass production in the second revolution
  • third introduced the digital revolution
  • The fourth industrial revolution is anxious to integrate technologies into our lives.

And all thanks to artificial intelligence (AI). An advanced technology that surrounds us, from virtual assistants to software that translates to self-driving cars.

The rise of AI at an exponential rate has disrupted almost every industry. So much so that AI is being rated as one-million-dollar profession.

Did this grab your attention? It did?

Now, what if we were to tell you that the salary compensation for AI experts has grown dramatically. AI and machine learning are fields that have a mountain of demand in the tech industry today but has sparse supply.

AI field is growing at a quicker pace and salaries are skyrocketing! Read it for yourself to know what AI experts, AI researchers and any other AI talent are commanding today.

  • A top-class AI research laboratory, OpenAI says that techies in the AI field are projected to earn a salary compensation ranging between $300 to $500k for fresh graduates. However, expert professionals could earn anywhere up to $1m.
  • Whopping salary package of above 100 million yen that amounts to $1m is being offered to AI geniuses by a Japanese firm, Start Today. A firm that operates a fashion shopping website named Zozotown.

Does this leave you with a question – Is this a right opportunity for you to jump in the field and make hay while the sun is shining? 

And the answer to this question is – yes, it is the right opportunity for any developer seeking a role in the AI industry. It can be your chance to bridge the skill shortage in the AI field either by upskilling or reskilling yourself in the field of AI.

There are a wide varieties of roles available for an AI enthusiast like you. And certain areas are like AI Engineers and AI Researchers are high in demand, as there are not many professionals who have robust AI knowledge.

According to a job report, “The Future of Jobs 2018,” a prediction was made suggesting that machines and algorithms will create around 133 million new job roles by 2022.

AI and machine learning will dominate the tech world. The World Economic Forum says that several sectors have started embracing AI and machine learning to tackle challenges in certain fields such as advertising, supply chain, manufacturing, smart cities, drones, and cybersecurity.

Unraveling the AI realm

From chatbots to financial planners, AI is impacting the way businesses function on a day-today basis. AI makes the work simpler, as it provides variables, which makes the work more streamlined.

Alright! You know that

  • the demand for AI professionals is rising exponentially and that there is just a trickle of supply
  • the AI professionals are demanding skyrocketing salaries

However, beyond that how much more do you know about AI?

Considering the fact that our lives have already been touched by AI (think Alexa, and Siri), it is just a matter of time when AI will become an indispensable part of our lives.

As Gartner predicts that 2020 will be an important year for business growth in AI. Thus, it is possible to witness significant sparks for employment growth. Though AI predicts to diminish 1.8 million jobs, it is also said to replace it with 2.3 million jobs that will be created. As we look forward to stepping into 2020, AI-related job roles are set to make positive progress of achieving 2 million net-new employments by 2025.

With AI promising to score fat paychecks that would reach millions, AI experts are struggling to find new ways to pick up nouveau skills. However, one of the biggest impacts that affect the job market today is the scarcity of talent in this field.

The best way to stay relevant and employable in AI is probably by “reskilling,” and “upskilling.” And  AI certifications is considered ideal for those in the current workforce.

Looking to upskill yourself – here’s how you can become an AI engineer today.

Top three ways to enhance your artificial intelligence career:

  1. Acquire skills in Statistics and Machine Learning: If you’re getting into the field of machine learning, it is crucial that you have in-depth knowledge of statistics. Statistics is considered a prerequisite to the ML field. Both the fields are tightly related. Machine learning models are created to make accurate predictions while statistical models do the job of interpreting the relationship between variables. Many ML techniques heavily rely on the theory obtained through statistics. Thus, having extensive knowledge in statistics help initiate the first step towards an AI career.
  2. Online certification programs in AI skills: Opting for AI certifications will boost your credibility amongst potential employers. Certifications will also enhance your earning potential and increase your marketability. If you’re looking for a change and to be a part of something impactful; join the AI bandwagon. The IT industry is growing at breakneck speed; it is now that businesses are realizing how important it is to hire professionals with certain skillsets. Specifically, those who are certified in AI are becoming sought after in the job market.
  3. Hands-on experience: There’s a vast difference in theory and practical knowledge. One needs to familiarize themselves with the latest tools and technologies used by the industry. This is possible only if the individual is willing to work on projects and build things from scratch.

Despite all the promises, AI does prove to be a threat to job holders, if they don’t upskill or reskill themselves. The upcoming AI revolution will definitely disrupt the way we work, however, it will leave room for humans to perform more creative jobs in the future corporate world.

So a word of advice is to be prepared and stay future ready.
