LIBSVM -- A Library for Support Vector Machines

https://www.csie.ntu.edu.tw/~cjlin/libsvm/

LIBSVM is an integrated software for support vector classification, (C-SVC, nu-SVC), regression (epsilon-SVR, nu-SVR) and distribution estimation (one-class SVM). It supports multi-class classification.

Since version 2.8, it implements an SMO-type algorithm proposed in this paper:
R.-E. Fan, P.-H. Chen, and C.-J. Lin. Working set selection using second order information for training SVM. Journal of Machine Learning Research 6, 1889-1918, 2005. You can also find a pseudo code there. (how to cite LIBSVM)

Our goal is to help users from other fields to easily use SVM as a tool. LIBSVM provides a simple interface where users can easily link it with their own programs. Main features of LIBSVM include

  • Different SVM formulations
  • Efficient multi-class classification
  • Cross validation for model selection
  • Probability estimates
  • Various kernels (including precomputed kernel matrix)
  • Weighted SVM for unbalanced data
  • Both C++ and Java sources
  • GUI demonstrating SVM classification and regression
  • PythonRMATLABPerlRubyWekaCommon LISPCLISPHaskellOCamlLabVIEW, and PHP interfaces. C# .NET code and CUDA extension is available. 
    It's also included in some data mining environments: RapidMinerPCP, and LIONsolver.
  • Automatic model selection which can generate contour of cross validation accuracy.
