Perceptrons

Summary

The simplest neural unit — a weighted sum passed through a step function — historically the first neural network model and still the conceptual starting point for understanding layers.

• 1Implement a single perceptron from scratch and train it on a linearly separable dataset.
• 2Learn why a single perceptron can't solve XOR (the motivation for multi-layer networks).
• 3Connect the perceptron to logistic regression — they're nearly identical.
