Seeking Physics in Diffusion Noise
📰 ArXiv cs.AI
Researchers find that video diffusion models can encode signals predictive of physical plausibility, allowing for partial separation of plausible and implausible videos in feature space
Action Steps
- Analyze intermediate denoising representations of a pretrained Diffusion Transformer (DiT)
- Probe mid-layer feature space across noise levels to identify separability of physically plausible and implausible videos

Abstract:
arXiv:2603.14294v2 Announce Type: replace-cross Abstract: Do video diffusion models encode signals predictive of physical plausibility? We probe intermediate denoising representations of a pretrained Diffusion Transformer (DiT) and find that physically plausible and implausible videos are partially separable in mid-layer feature space across noise levels. This separability cannot be fully attributed to visual quality or generator identity, suggesting recoverable physics-related cues in frozen Di
