PAWBench: How Far Are We from Probabilistically Aligned World Modeling?
Provides rigorous evaluation framework for researchers developing world models and video generation systems.
AI Summary
Researchers introduce PAWBench, a evaluating video generation models' probabilistic with real-world dynamics across 50 scenarios.
Excerpt
Recent video generation models are increasingly framed as world models. Many physical processes can unfold in more than one valid way. Therefore, a world model should reproduce not only a plausible trajectory, but also the distribution of possible behaviors under the same initial observation and action. We call this distribution-level requirement probabilistic alignment. However, existing evaluations largely assess individual-video plausibility and do not test whether repeated generations recove
