Cold Diffusion: Inverting Arbitrary Image Transforms Without Noise [PDF]
Neural Information Processing Systems, 2022 Standard diffusion models involve an image transform -- adding Gaussian noise -- and an image restoration operator that inverts this degradation. We observe that the generative behavior of diffusion models is not strongly dependent on the choice of image

An optimal control problem without control costs
Mathematical Biosciences and Engineering, 2023 A two-dimensional diffusion process is controlled until it enters a given subset of $ \mathbb{R}^2 $. The aim is to find the control that minimizes the expected value of a cost function in which there are no control costs.

Reduced Markovian Descriptions of Brownian Dynamics: Toward an Exact Theory
Frontiers in Physics, 2022 We outline a reduction scheme for a class of Brownian dynamics which leads to meaningful corrections to the Smoluchowski equation in the overdamped regime.
