Feature selection tool is a simple python script to use F-score for selecting features. To run it, please put it in the sub-directory "tools" of LIBSVM.
Output files: .fscore shows importance of features, .select gives the running log, and .pred gives testing results.
More information about this implementation can be found in Y.-W. Chen and C.-J. Lin, Combining SVMs with various feature selection strategies. To appear in the book "Feature extraction, foundations and applications." 2005. This implementation is still preliminary. More comments are very welcome.
