The AdaBoost algorithm creates an ensemble of weak classifiers. Before determining the next weak classifier, which one of the following is done by the AdaBoost algorithm?
A. Chooses a new random subset of the training examples to use
B. Decreases the weights of the training examples that were misclassified by the previous weak classifier
C. Increases the weights of the training examples that were misclassified by the previous weak classifier
D. Removes the training examples that were classified correctly by the previous weak classifier
Answer:C
