Language models accelerate POMDP world model learning

Researchers have developed Pinductor, a novel method for learning world models in partially observable Markov decision processes (POMDPs) by leveraging language model priors. This approach uses an LLM to propose and refine POMDP models from limited observation-action trajectories, significantly reducing the need for extensive environment interaction. Pinductor demonstrates comparable performance and sample efficiency to methods using privileged state information and is substantially more sample-efficient than standard POMDP baselines like DreamerV3, while maintaining similar computational costs.

IMPACT Presents a new method for sample-efficient world-model learning, potentially enabling more capable generalist agents with less data.
