Non-Linearity
Domain: AI Fundamentals
🎯 Motivation
The ability to model curved, complex relationships, not just straight lines. Comes from activation functions.
📋 Concrete Example
Without non-linearity, a 100-layer network collapses to the equivalent of one linear layer.
🔗 Analogy
Like being able to draw curves and squiggles, not just rulers-straight lines, on a graph.
