Scilab Module : libsvm and liblinear (original) (raw)

        This tool provides a simple interface to LIBSVM, a library for support vector

machines (http://www.csie.ntu.edu.tw/~cjlin/libsvm). It is very easy to use as the usage and the way of specifying parameters are the same as that of LIBSVM.

This tool provides also a simple interface to LIBLINEAR, a library for large-scale regularized linear classification (http://www.csie.ntu.edu.tw/~cjlin/liblinear). It is very easy to use as the usage and the way of specifying parameters are the same as that of LIBLINEAR.

This Toolbox is compatible with the NaN-toolbox!

This interface was initially written by Jun-Cheng Chen, Kuan-Jen Peng, Chih-Yuan Yang and Chih-Huai Cheng from Department of Computer Science, National Taiwan University.

It was converted to Scilab 5.3 by Holger Nahrstaedt from TU Berlin.
