Artificial Intelligence By Example

Metrics

Metrics are there to measure the performance of your model. The metric function behaves like a loss function. However, it is not used to train the model.

In this case, the accuracy parameter was this:

...metrics = ['accuracy'])

Here, a value that descends towards 0 shows whether the training is on the right track and moves up to one when the training requires Adam function optimizing to set the training on track again.
