Andreas Hoecker (CERN), Eckhard Von Toerne (Rheinische-Friedrich-Wilhelms- Univ.-Univ. Bonn, Physikalisches), Helge Voss (Physik-Institut), Jan Therhaag (Univ. Bonn, Physikalisches Institut), Joerg Stelzer (DESY), Peter Speckmayer (CERN)
Description
Given the increasing complexity of modern HEP experiments, multivariate analysis techniques have proven indispensable to extract the maximum information content out of the data. At this workshop we will review recent developments on multivariate methods in TMVA (the Toolkit for Multivariate Data Analysis in ROOT), discuss user experience and feedback, and explain the use of TMVA by means of a hands-on tutorial. The workshop directly succeeds Phystat 2011 at CERN.

EVO phone connection will be provided for remote participants.

The schedule leaves room for user feedback on TMVA, and ideas for new multivariate approaches or improvements on existing methods.

Please submit talk proposals to tmva-workshop@cern.ch

If you wish to attend the workshop and/or TMVA tutorial please register as soon as possible, so that we can plan for an appropriate location at CERN.
