Multiclass classification is a more general form classifying training samples in categories. The strict form of this is probably what you guys have already heard of binary. classification ( Spam/Not Spam or Fraud/No Fraud). For our example, we will be using the stack overflow dataset and assigning tags to …

Actually, there is no metric named accuracy in Keras. When you set metrics=['accuray'] in Keras, the correct accuracy metric will be inferred automatically based on the loss function used. As a result, since you have used binary_crossentropy as the loss function, the binary_accuracy will be chosen as the metric.. Now, you should definitely choose binary_accuracy over categorical_accuracy in a
