Data Mining and Predictive Analysis

Data mining is the process of discovering useful patterns and trends in large data sets and predictive analytics is the process of extracting information from large data sets in order to make predictions and estimates about future outcomes. Data mining is becoming more widespread every day, because it empowers companies to uncover profitable patterns and trends from their existing databases. With uCertify’s course Data mining and predictive analysis, you get a hands-on experience in data mining and you will learn what types of analysis will uncover the most profitable nuggets of knowledge from the data, while avoiding the potential pitfalls that may cost your company millions of dollars.
