Convex Function
Domain: Math & Logic for AI
🎯 Motivation
A bowl-shaped function with one global minimum. Easy to optimize - any downhill path reaches the bottom.
📋 Concrete Example
f(x) = x squared is convex. Gradient descent always finds the bottom, no matter where you start.
🔗 Analogy
Like a smooth bowl - a marble rolled from anywhere will settle at the lowest point.
