Software and research projects

• LIBSVM : a simple and easy-to-use support vector machines tool for classification (C-SVC, nu-SVC), regression (epsilon-SVR, nu-SVR), and distribution estimation.
  It includes a GUI for both classification and regression. Version 1.0 released April 2000. Current Version: 3.12, April 2012.
  See software document published in ACM TIST: pdf, ps.gz, ACM digital lib.
• LIBLINEAR: a library for large linear classification. It is very suitable for document classification. Version 1.0 released April 2007. Current Version: 1.91, April 2012.
• BSVM : a simple decomposition method for support vector machines for large classification.
  It has faster convergence in difficult cases. Version 1.0 released January 2000. Current Version: 2.07, May 2012.
• NMF : a simple and easy-to-use MATLAB code for Nonnegative Matrix Factorization.
  Version 1.0 released October 2005. Current Version: 1.01, December 2005.
• TRON: Trust region Newton Method for large bound-constrained optimization, released June 1999. We also provide an AMPL interface in NEOS.
• Other miscellaneous software
