Researchers have developed a novel method called Round-Trip Consistency (RTC) that allows bidirectional diffusion models to predict their own rollout errors without needing ground truth data. This technique involves training a single conditional latent diffusion model that can step a dynamical system both forward and backward in time. The discrepancy in returning to the starting point after an equal number of forward and backward steps serves as a self-supervised proxy for unobservable rollout errors. RTC has been validated on various applications, including compressible magnetohydrodynamics, turbulent radiative mixing layers, and natural face videos, demonstrating its effectiveness in error detection and even reducing incurred error.
