A limitation of such an approach is that it requires learning about object dynamics solely from reward values assigned to the final state of a rollout of the environment. This study aims to address this limitation by augmenting the reward value with self-supervised signals about object dynamics. Specifically, we train the model to characterize the similarity of two environment rollouts, jointly with predicting the outcome of the reasoning task. This similarity can be defined as a distance measure between the trajectory of objects in the two rollouts, or learned directly from pixels using a contrastive formulation. Empirically, we find that this approach leads to substantial performance improvements on the PHYRE benchmark for physical reasoning (Bakhtin et al., 2019), establishing a new state-of-the-art.","url_abs":"https://arxiv.org/abs/2102.10336v2","url_pdf":"https://arxiv.org/pdf/2102.10336v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"physical-reasoning-using-dynamics-aware","repo_url":"https://github.com/facebookresearch/DynamicsAware","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"pytorch","reach":{"status":"unanswered"}}],"tasks":[{"task_slug":"visual-reasoning","task_name":"Visual Reasoning"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/visual-reasoning-on-phyre-1b-cross","task":"Visual Reasoning","dataset":"PHYRE-1B-Cross","model":"Dynamics-Aware DQN","rank_in_archive_order":3,"of":4,"metrics":{"AUCCESS":"39.9"},"uses_additional_data":false},{"leaderboard":"/sota/visual-reasoning-on-phyre-1b-within","task":"Visual Reasoning","dataset":"PHYRE-1B-Within","model":"Dynamics-Aware DQN","rank_in_archive_order":2,"of":4,"metrics":{"AUCCESS":"85.2"},"uses_additional_data":false}],"syntology":{"atlas_url":"https://app.syntology.ai/?focus=2102.10336","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
