19 Artificial Neural Networks - Classification with Multi-Layer Perceptron

20 ANN - An MLP is often used for classification, with each output corresponding to a different binary class.

21 ANN - When the classes are exclusive(like cat, dog, parrot classification problem), the output layer of a Multi-Layer Perceptron is typically modified by replacing the individual activation functions with a shared sigmoid function.

24 ANN - If we have the class label in the form of a one-hot vector, we could use `categorical_crossentropy`. Else if the class label is an integer index, we use `sparse_categorical_cross entropy`.

25 ANN - Which of the following activation functions would we use for the output classification layer in a classification problem with 5 exclusive classes?

26 ANN - The value of softmax and sigmoid is in the range 0 and 1.

30 ANN - When we evaluate a wide and deep model, Keras will return the total loss, as well as all the individual losses.

31 ANN - A wide and deep network could be used to perform two simultaneous tasks of classification using the same input data.

32 Artificial Neural Networks - Saving and Restoring Models

33 ANN - Keras will use the HDF5 format to save which of the following of a trained model?

34 ANN - Callbacks argument of fit() allows us to specify a list of objects that Keras will call at the start and end of the training, at the start and end of each epoch, and even before and after processing each batch.

35 ANN - ModelCheckpoint callback is used in conjunction with training using model.fit() to save a model or weights (in a checkpoint file) at some interval, so the model or weights can be loaded later to continue the training from the state saved.
