ChatGPT, DALL-E, AlphaFold, Stable Diffusion — every major AI breakthrough runs on the same foundation: a neural network. In this episode we build the complete intuition from scratch: the artificial neuron, activation functions, layers, the forward pass, backpropagation, and what deep networks actually learn — all without a single equation.

In this episode:
→ The artificial neuron — inputs, weights, bias, activation function
→ Why activation functions (especially ReLU) are the key to deep learning's power
→ Building a network — input, hidden, and output layers explained visually
→ The forward pass — how data flows through the network
→ Backpropagation — how the network learns from its mistakes
→ What each layer actually learns — the hierarchical representation discovery
→ The through-line: how this episode explains CNNs, Transformers, and LLMs

This is Episode 15 of Master AI & Machine Learning — Module 3: Core ML Algorithms, Episode 5 of 6.
