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 in April 2000. Current Version: 3.35, September 2024.
  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 in April 2007. Current Version: 2.48, January 2025.
