- Abstract summary: We transform offline reinforcement learning into a supervised learning task by integrating multimodal and pre-trained language models.
Our approach incorporates state information derived from images and action-related data obtained from text.
Our method significantly outperforms current baselines as evidenced by evaluations conducted on Atari and OpenAI Gym environments.

- Abstract: Drawing upon the intuition that aligning different modalities to the same
semantic embedding space would allow models to understand states and actions
more easily, we propose a new perspective to the offline reinforcement learning
(RL) challenge. More concretely, we transform it into a supervised learning
task by integrating multimodal and pre-trained language models. Our approach
incorporates state information derived from images and action-related data
obtained from text, thereby bolstering RL training performance and promoting
long-term strategic thinking. We emphasize the contextual understanding of
language and demonstrate how decision-making in RL can benefit from aligning
states' and actions' representation with languages' representation. Our method
significantly outperforms current baselines as evidenced by evaluations
conducted on Atari and OpenAI Gym environments. This contributes to advancing
offline RL performance and efficiency while providing a novel perspective on
offline RL.Our code and data are available at

We consider investigating the potential connection between offline reinforcement learning (RL) and language modeling (LM)
RL and LM are similar in predicting the next states based on the current and previous states, which rely on both local and long-range dependency across states.
Experimental results show that our RL pre-trained models can give close performance compared with the models using the LM training objective.

They also probe the limits of existing RvS methods, which are comparatively weak on random data.
