Feature selection and reduction are key to robust multivariate analyses. In this talk I will focus on pros and cons of various variable selection methods and focus on those that are most relevant in the context of HEP.

6. TMVA tutorial

Helge Voss (Max-Planck-Gesellschaft (DE)), Dr Sergei Gleyzer (University of Florida (US))

This tutorial will both give an introduction on how to use TMVA in root6 and showcase some new features, such as modularity, variable importance, interfaces to R and python. After explaining the basic functionality, the typical steps required during a real life application (such as variable selection, pre-processing, tuning and classifier evaluation) will be demonstrated on simple examples....
