UnverifiedReinforcement learning is one of the three major paradigms of machine learning, in which an agent adjusts its behavioral policy by interacting with an environment and following reward or punishment signals, with its core idea derived from operant conditioning in behavioral psychology.77% similarUnverifiedThe essence of reinforcement learning is to have the model continuously optimize to maximize a certain reward signal.76% similarUnverifiedAlphaGo is a landmark achievement of reinforcement learning, and RLHF (Reinforcement Learning from Human Feedback) is applied to large language model alignment.74% similarUnverifiedModel-based reinforcement learning improves sample efficiency by learning a dynamics model of the environment for planning, with representative methods including Dreamer and MBPO.71% similarUnverifiedThe quality of a reinforcement learning environment directly determines what the model can learn, and an environment with loopholes may allow the model to learn to game the system.69% similar
