Kolmogorov Regression for Robust Diffusion Policies
Researchers introduced a method to improve diffusion policies used in physical systems by addressing temporal drift issues. The approach involves a backward Kolmogorov equation that transforms diffusion policies into a more stable mathematical space. This change replaces a stochastic problem with a deterministic PDE problem, leveraging Gaussian measure theory. The innovation aims to enhance long-horizon performance in real-world applications.
Key takeaways
- Transforms diffusion policies into Cameron-Martin space for stability.
- Replaces stochastic score matching with deterministic PDE problem.
- Aims to improve long-horizon performance in physical systems.
