arXiv:2606.18186v1 Announce Type: cross Abstract: Finite-dimensional (FD) diffusion policies exhibit temporal drift owing to discretization artifacts that degrade long-horizon performance (when deployed on physical systems). We introduce a backward Kolmogorov equation that lifts diffusion policies to a Cameron-Martin space -- a subset of the Hilbert space. Essentially, replacing stochastic score matching with a deterministic boundary-value PDE problem. Our core innovation thrives on Gaussian measure theory whereupon the diffusion noise covariance operator is realized from a colored noise distr
This development addresses a fundamental limitation in current diffusion policies, critical for deploying AI systems on physical platforms, as the field matures beyond theoretical benchmarks.
Improving robustness and long-horizon performance of diffusion policies directly impacts the reliability and practical applicability of AI in real-world physical systems, from robotics to autonomous vehicles.
The computational approach shifts from stochastic methods to a deterministic boundary-value PDE, offering a more stable and potentially scalable solution for complex AI control problems.
