WebOne-hot encoding in Keras. The Keras API provides a to_categorical () method that can be used to one-hot encode integer data. If the integer data represents all the possible values of the classes, then the to_categorical () method can be used directly; otherwise, the number of classes can be passed to the method as the num_classes parameter.
