Simple Linear Regression Being in the field of data science, we all are familiar with at least some of the measures shown in figure 1.1 (generated in python using statsmodels). But do we really understand how these measures are being calculated? or what is the math behind these measures? In this article, I hope that […]

Cross-industry standard process for data mining

Introduced in 1996, the cross-industry standard process for data mining (CRISP-DM) became the most common procedure for all data mining projects. This method consists of six phases: Business understanding, Data understanding, Data preparation, Modeling, Evaluation and Deployment (see Figure 1). It is being used not just as a reference manual but as a user guide […]

Predictive maintenance in Semiconductor Industry: Part 1

The process in the semiconductor industry is highly complicated and is normally under consistent observation via the monitoring of the signals coming from several sensors. Thus, it is important for the organization to detect the fault in the sensor as quickly as possible. There are existing traditional statistical based techniques however modern semiconductor industries have […]
