| 12 | +abstract: 'Sparse rewards pose a significant challenge for many reinforcement learning |
| 13 | + algorithms, which struggle in the absence of a dense, well-shaped reward function. |
| 14 | + Drawing inspiration from the curiosity exhibited in animals, intrinsically-driven |
| 15 | + methods overcome this drawback by incentivizing agents to explore novel states. |
| 16 | + Yet, in the absence of domain-specific priors, sample efficiency is hindered as |
| 17 | + most discovered novelty has little relevance to the true task reward. We present |
| 18 | + iLLM, a curiosity-driven approach that leverages the inductive bias of foundation |
| 19 | + models — Large Language Models, as a source of information about plausibly useful |
| 20 | + behaviors. Two tasks are introduced for shaping exploration: 1) action generation |
| 21 | + and 2) history compression, where the language model is prompted with a description |
| 22 | + of the state-action trajectory. We further propose a technique for mapping state-action |
| 23 | + pairs to pretrained token embeddings of the language model in order to alleviate |
| 24 | + the need for explicit textual descriptions of the environment. By distilling prior |
| 25 | + knowledge from large language models, iLLM encourages agents to discover diverse |
| 26 | + and human-meaningful behaviors without requiring direct human intervention. We evaluate |
| 27 | + the proposed method on BabyAI-Text, MiniHack, Atari games, and Crafter tasks, demonstrating |
| 28 | + higher sample efficiency compared to prior curiosity-driven approaches.' |
