AlphaZero

Quick explainer2 min readIntermediate

AlphaZero is a DeepMind algorithm that taught itself chess, shogi and Go from scratch, given only the rules, and beat top programs in all three.

In plain words

AlphaGo first learned from human games. AlphaZero started with nothing but the rules and random moves. It improved by playing game after game against itself, using reinforcement learning to update a neural network that guides its search. The same general method worked for three different games, and within 24 hours of training it had reached superhuman strength in each one.

A quick example

At the start of training AlphaZero's chess moves are random. After many self-play games, its network has learned which positions tend to win, and it defeated a world-champion chess program.
