Class separation

Learning rate

The perceptron — the ancestor of every neural network — nudges a straight boundary each time it misclassifies a point. If the two classes are linearly separable it is guaranteed to find a dividing line; if they overlap, it never quite settles. Educational tool.

Governing equation

\overset{y}{^} = step (w \cdot x + b), w \leftarrow w + 0.10 (y - \overset{y}{^}) x

Reading this result: Moderate separation with a gentle learning rate: the boundary drifts steadily toward a clean split over many passes.
