What is reinforcement learning vs machine learning?

RL learns behaviors via trial-error rewards in dynamic worlds; ML predicts labels from fixed data.

How does MDP work in reinforcement learning?

MDP defines states, actions, transitions, rewards, discount—frames any RL problem before algorithms kick in.

Bellman equation reinforcement learning simple explanation?

Value now = immediate reward + discounted future value; recurses to assign credit across time.

Reinforcement Learning's Secret: It's Not ML in Disguise

AlphaZero mastered chess, Go, and shogi from scratch in 24 hours flat—no human games needed. That's reinforcement learning doing what supervised ML dreams of, but with a mindset flip that trips up even pros.
