English(EN) ARC-Bench: Closed-Loop Replanning Masks Broken Action Ranking in Frozen JEPA World Models

新的ARC-Bench协议揭示了冻结JEPA世界模型的关键缺陷

研究人员开发了ARC-Bench,一个旨在评估冻结潜在世界模型动作排序能力的新评估协议。研究发现,这些通过根据预测的未来嵌入对候选动作进行评分来进行规划的模型,常常无法正确排序动作。由于闭环重规划机制,这一缺陷在很大程度上未被发现,导致次优的动作选择,并夸大了潜在表征的真实性能。即使使用不同的视觉骨干网络,包括V-JEPA 1和V-JEPA 2,研究结果也保持一致。 AI

影响 揭示了当前世界建模方法的根本性局限性,可能影响更鲁棒的AI规划和控制系统的开发。

    ARC-Bench:闭环重规划掩盖了冻结JEPA世界模型中损坏的动作排序

    arXiv:2609.05461v1 Announce Type: new Abstract: Reward-free latent world models plan by scoring candidate actions with distances in a frozen latent space: an action is preferred if its predicted future embedding lands closer to the goal embedding. This silently assumes that laten…
