Data Mining Techniques: Theory and Practice

GK# 2826

JUMP TO:

Course Overview

TOP

In this course, you will learn about data mining methodology that is a superset to the SAS SEMMA methodology around which SAS Enterprise Miner is organized. You will also learn about a wide range of data mining algorithms as well as theoretical knowledge and practical skills. In this class, you will work through all the steps of a data mining project, beginning with problem definition and data selection, and continuing through data exploration, data transformation, sampling, portioning, modeling, and assessment.
