Hyper-Diffusion: Estimating Epistemic and Aleatoric Uncertainty with a Single Model

no code implementations5 Feb 2024 Matthew A. Chan, Maria J. Molina, Christopher A. Metzler

In this work we introduce a new approach to ensembling, hyper-diffusion, which allows one to accurately estimate epistemic and aleatoric uncertainty with a single model.

SUD$^2$: Supervision by Denoising Diffusion Models for Image Reconstruction

no code implementations16 Mar 2023 Matthew A. Chan, Sean I. Young, Christopher A. Metzler

Many imaging inverse problems$\unicode{x2014}$such as image-dependent in-painting and dehazing$\unicode{x2014}$are challenging because their forward models are unknown or depend on unknown latent parameters.
