SVMTrainAuto Method (TrainData, Int32, MCvParamGrid, MCvParamGrid, MCvParamGrid, MCvParamGrid, MCvParamGrid, MCvParamGrid, Boolean) |
http://www.emgu.com
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
- Type: Emgu.CV.MLTrainData
The training data. - kFold
- Type: SystemInt32
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
- Type: Emgu.CV.MLMCvParamGrid
cGrid - gammaGrid
- Type: Emgu.CV.MLMCvParamGrid
grid for gamma - pGrid
- Type: Emgu.CV.MLMCvParamGrid
grid for p - nuGrid
- Type: Emgu.CV.MLMCvParamGrid
grid for nu - coefGrid
- Type: Emgu.CV.MLMCvParamGrid
grid for coeff - degreeGrid
- Type: Emgu.CV.MLMCvParamGrid
grid for degree - balanced (Optional)
- Type: SystemBoolean
If true and the problem is 2-class classification then the method creates more balanced cross-validation subsets that is proportions between classes in subsets are close to such proportion in the whole train dataset.
Return Value
Type:
BooleanTrue if training is successful.
