Decode the Classifier’s Answers

Overview of classifier

Let’s review how classify() works. During the classification phase, the WSSs return arrays of ten numbers from $0$ to $1$. But when we ask the system to recognize an image, we do not want to see those arrays, we want a human-readable answer such as “$3$.” This means that we must decode the WSSs’ answers before returning them.

So far, the classify() function didn’t have much to do, apart from calling forward() and rounding its output. Now classify() has a more complex job. It must convert the output of the WSSs back to human-readable labels, like this:
