|
|
|
(one-class SVM). It supports multi-class classification.

Since version 2.8, it implements an SMO-type algorithm proposed in this paper:

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
|
|
|
|
|
* Weighted SVM for unbalanced data
|
|
|
|
|
* Both C++ and Java sources
|
|
|
|
|
* GUI demonstrating SVM classification and regression
|
|
|
|
|
* Python, R (also Splus), MATLAB, Perl, Ruby, Weka, Common LISP and LabVIEW
|
|
|
|
|
interfaces. C# .NET code is available.
|
|
|
|
|
It's also included in some learning environments: YALE and PCP.
|
|
|
|
|
* Automatic model selection which can generate contour of cross valiation
|
|
|
|
|
accuracy.
