Predicting output

When a net is trained, it can be course be used for predictions. In Keras, this is very simple. We can use the following method:

# calculate predictions
predictions = model.predict(X)

For a given input, several types of output can be computed, including a method:

• model.evaluate(): This is used to compute the loss values
• model.predict_classes(): This is used to compute category outputs
• model.predict_proba(): This is used to compute class probabilities
