Data Mining and Predictive Analytics

Objective

The ability to collect and store data has increased significantly as a result of advances in various areas, such as the Internet, electronic commerce, electronic transactions, readers’ bar-code, mobile devices and intelligent machines. Data mining is a rapidly growing research area that deals with the development of techniques that aim to help data owners to make smart use of these data collections. Also in conjunction with forecasting techniques can leverage existing information to make predictions and decisions.
In this course we will study methods for data analysis, knowledge extraction from voluminous data collections as well as techniques for forecasting and decision making.
