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. The basic algorithm
-is a simplification of both SMO by Platt and SVMLight by Joachims. It is also
-a simplification of the modification 2 of SMO by Keerthi et al.

-Our goal is to help users from other fields to easily use SVM as a tool.
