Concept of the week
The learning rate decides whether training ever settles
Gradient descent moves a parameter a little way downhill on every step. The learning rate sets how far. Here the loss is a simple bowl, so the best value of x is 0.
x ← x − η · dL/dx where L(x) = x²
Try a tiny rate, then something near 0.5, then push past 1.0. On this bowl every step multiplies x by (1 − 2η), so any rate above 1.0 makes each step overshoot further than the last.
