Understanding the testing matrix

In this section, we will look at the testing matrix for the facial emotion application. The concept of testing is really simple. We need to start observing the training steps. We are tracking the values for loss and accuracy. Based on that, we can decide the accuracy of our model. Doesn't this sound simple? We have trained the model for 30 epochs. This amount of training requires more than three hours. We have achieved 63.88% training accuracy. Refer to the code snippet in the following diagram:

This is the training accuracy. If we want to check ...
