SVM_Train


Trains SVM model

Name Type Description
inSvmModel SvmModel Initialized SVM model
inVectorArray RealArrayArray Training data vector array
inAnswerArray IntegerArray Correct classes for data vectors
outTrainedSvmModel SvmModel Trained model
outTrainingAccuracy Real Accuracy of prediction on training set

Description

The operation trains an SVM classifier initialized beforehand by SVM_Init function. It takes two arrays as arguments:

  • inVectorArray, an array of data points with known classes
  • inAnswerArray, an array of classes where the corresponding data points belong

Those two arrays have to be of the same size. Moreover, there have to be at least two classes within the training data set.

The output outTrainedSvmModel is an SVM_Model that may be used by SVM_Classify function.

outTrainingAccuracy is the fraction of correctly classified training data points.

Errors

This filter can throw an exception to report error. Read how to deal with errors here: Error Handling

DomainError Incorrect or uninitialized SvmModel in Svm_Train.
DomainError Cannot re-train SvmModel.
DomainError Data vector cannot be empty in SVM_Train
DomainError Incompatible vector sizes in SVM_Train
