Member Function Documentation

inline

This function is called to update the weightVectors matrix.

It decreases the weights of the incorrectly classified class while increasing the weight of the correct class it should have been classified to.

Template Parameters

Type	of vector (should be an Armadillo vector like arma::vec or arma::sp_vec or something similar).

Parameters

trainingPoint	Point that was misclassified.
weights	Matrix of weights.
biases	Vector of biases.
incorrectClass	Index of class that the point was incorrectly classified as.
correctClass	Index of the true class of the point.
instanceWeight	Weight to be given to this particular point during training (this is useful for boosting).
