      extended by imp.classifier.SvmClassifier

public class SvmClassifier
extends Classifier

Defines a standard C-SVM classifier.

This is a direct interface with 1-to-1 SVM multi-class classifier developed by Chih-Chung Chang and Chih-Jen Lin as a free-ware open-source software, thanks to their courtesy. It is included in the present bundle.
Only a simple interface is proposed here.
Please refer to the on-line doc for details.
