The method trains the SVM model automatically by choosing the optimal parameters C, gamma, p, nu, coef0, degree from CvSVMParams. By the optimality one mean that the cross-validation estimate of the test set error is minimal.

Parameters

trainData
Matrix<(Of <(<'Single>)>)>
The training data.
responses
Matrix<(Of <(<'Single>)>)>
The response for the training data.
varIdx
Matrix<(Of <(<'Byte>)>)>
Can be null if not needed. When specified, identifies variables (features) of interest. It is a Matrix<int> of nx1
sampleIdx
Matrix<(Of <(<'Byte>)>)>
Can be null if not needed. When specified, identifies samples of interest. It is a Matrix<int> of nx1
parameters
MCvSVMParams
The parameters for SVM
kFold
Int32
Cross-validation parameter. The training set is divided into k_fold subsets, one subset being used to train the model, the others forming the test set. So, the SVM algorithm is executed k_fold times
cGrid
MCvParamGrid
cGrid
gammaGrid
MCvParamGrid
gammaGrid
pGrid
MCvParamGrid
pGrid
nuGrid
MCvParamGrid
nuGrid
coefGrid
MCvParamGrid
coedGrid
degreeGrid
MCvParamGrid
degreeGrid
