Researchers have introduced LANTERN, a novel framework designed to enhance transfer learning in reinforcement learning (RL) by integrating knowledge from multiple source tasks. Unlike previous methods that relied on manual task specifications and single sources, LANTERN utilizes large language models to generate task automata from natural language descriptions. It adaptively aggregates policies from various sources, weighting them based on inter-task similarity and temporal-difference errors, leading to significant improvements in sample efficiency. AI
