The cheapest path to learn RL: David Silver lectures, DQN, PPO, GRPO — all on a laptop

cneuralnetwork · x · 2026-11-01

A practical self-study path for reinforcement learning: watch David Silver's free lectures, implement multi-armed bandits, code Q-learning from scratch, build DQN on CartPole, learn policy gradients and PPO, train an agent in Gymnasium, then read the GRPO paper to connect it to LLM post-training. Most RL fundamentals can be learned on a laptop; full resource links are in the replies.
