RBLIBSVC

Trainable automatic radial basis Support Vector Classifier by LIBSVM

    [W,KERNEL] = RBLIBSVC(A)
    [W,KERNEL] = A*RBLIBSVC

Input
A	Dataset

Output
W	Mapping: Radial Basis Support Vector Classifier
KERNEL	Untrained mapping, representing the optimised kernel

Description

This routine computes a classifier by LIBSVC using a radial basis kernel  with an optimised standard deviation by REGOPTC. The resulting classifier  W is identical to LIBSVC(A,KERNEL). As the kernel optimisation is based  on internal cross-validation the dataset A should be sufficiently large.  Moreover it is very time-consuming as the kernel optimisation needs  about 100 calls to LIBSVC.

Note that LIBSVC is basically a multi-class classifier. The kernel  is thereby the same for all classes. Use MCLASSC to find a multi-class  classifier composed by two-class classifiers with possibly different  kernels.
