Data Mining

 

The workshop is practical in nature. All contents are presented in the context of using WEKA and other tools, the most widely-used open source machine learning software in the world.

The workshop includes hands-on exercises using WEKA and other tools and data sets to do actual data mining. The course assumes no prior knowledge; but it is not a trivial treatment. It covers the basics and advances of machine learning, and surveys a majority of the most commonly used algorithms.
This is a practical course with design exercises. Participants are required to bring their laptops to the course.
