Traditional model-based reinforcement learning (MBRL) typically relies on an explicit world model to predict future states, such as reconstructing the next frame image.

VerifiedWorld models are essentially learned dynamical equations of an environment—given the current state and action, they predict the next state.76% similarUnverifiedClassic MBRL implementations (such as Dreamer and MuZero) typically require explicitly predicting the next frame observation or reward.76% similarUnverifiedModel-Based Reinforcement Learning (MBRL) allows agents to accumulate experience by running freely within a world model, potentially improving data efficiency by orders of magnitude.75% similarUnverifiedAn ideal world model predicts the next state given the current state and action; this next-frame prediction capability has commonalities with video generation.74% similarUnverifiedAn autoregressive world model refers to a generative model that takes the current or historical state as input and predicts future states step by step, commonly treating the scene representation at each moment as a token sequence and performing inference in temporal order with structures such as Transformers.74% similar
