New diffusion model guidance improves physical accuracy in simulations

Researchers have developed a novel physics-informed approach for diffusion models to generate more accurate spatiotemporal signals in fields like fluid dynamics. This method, termed Self-Augmented Diffusion Guidance, incorporates constraints from physical laws by learning the data distribution conditioned on deviations from correct dynamics. By setting these deviations to zero during generation, the model produces samples that adhere more closely to physical laws, avoiding the need for computationally expensive simulations at each denoising step. Experiments show this approach significantly reduces physical deviations compared to standard diffusion models and can further improve results when combined with existing physics-constrained methods.
