You Train a Keras Model by Calling Its Fit Method

question 65

Multiple Choice

You train a Keras model by calling its fit method. Which of the following statements about the fit method is false?

• A) As in Scikit-learn, the first two arguments are the training data and the categorical target labels.
• B) The iterations argument specifies the number of times the model should process the entire set of training data.
• C) batch_size specifies the number of samples to process at a time during each epoch. Most models specify a power of 2 from 32 to 512. Larger batch sizes can decrease model accuracy.
• D) In general, some samples should be used to validate the model. If you specify validation data, after each epoch, the model will use it to make predictions and display the validation loss and accuracy. You can study these values to tune your layers and the fit method's hyperparameters, or possibly change the layer composition of your model.
