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). |
