Contents:

Data 		  % Datasets of the NIPS 2003 feature selection challenge       
         
FiftySubsets  % Fifty good feature subsets provided by the challengers  

Clop 		  % Matlab code to read the data and build simple models

main.m        % Matlab file constituting an entry point to the baseline models
		  % See Clop/sample_code/README.txt and Clop/README.txt for details.
		  % The baseline models were created for educational purpose. 
              % They can easily be outperformed. In a class taught on feature 
              % selection, most students outperformed the baseline models on most
              % datasets. More teaching material can be found at:
		  % http://www.clopinet.com/isabelle/Projects/ETH

Models	  % Baseline models created by main, 
		  % reload e.g. with my_model=load_model('Models/baseline/gisette_model');

Results	  % Prediction results of the baseleine models (in the challenge format)

Zipped	  % Zip files ready to submit to the challenge web site 					        % http://www.nipsfsc.ecs.soton.ac.uk/

Score		  % Results obtained with the baseline models, computed by the program

The CLOP package is based on the Spider (http://www.kyb.tuebingen.mpg.de/bs/people/spider/)
developed at the Max Planck Institute for Biological Cybernetics. CLOP integrates software from several sources. It has been developed as part of the WCCI Performance Prediction Challenge.
