How a neural network learns

Six steps, one picture. What the boxes are, what the wires do, and what actually changes when a model is trained.

Prefer to go at your own pace? The same thing is below, one step at a time.

The stepper above is drawn by the page itself, so it costs nothing to load and works the same on a slow connection. The film is the same drawing, recorded, for when you would rather watch than tap.
