Function Composition
Domain: Math & Logic for AI
🎯 Motivation
Applying one function after another. Neural networks are deep compositions of simple functions.
📋 Concrete Example
If f(x) = x+1 and g(x) = x*2, then g(f(x)) = (x+1)*2. A 10-layer network composes 10 functions.
🔗 Analogy
Like a series of filters on a photo app - each filter feeds into the next, building the final image.
