Neuron
Domain: AI Fundamentals
🎯 Motivation
The basic unit of a neural network. It combines inputs and decides how much signal to pass forward.
📋 Concrete Example
A neuron takes 3 numbers, multiplies each by a weight, adds a bias, then applies ReLU. Output goes to the next layer.
🔗 Analogy
Like a single voter who weighs different rumors (inputs), adds their own bias, and decides whether to shout (activate).
