Learning normalized image densities via dual score matching

NeurIPS 2025poster

Learning probability models from data is at the heart of many machine learning endeavors, but is notoriously difficult due to the curse of dimensionality. We introduce a new framework for learning \emph{normalized} energy (log probability) models that is inspired from diffusion generative models, wh…

Generalization in diffusion models arises from geometry-adaptive harmonic representations

ICLR 2024oral

Deep neural networks (DNNs) trained for image denoising are able to generate high-quality samples with score-based reverse diffusion algorithms. These impressive capabilities seem to imply an escape from the curse of dimensionality, but recent reports of memorization of the training set raise the qu…

Learning multi-scale local conditional probability models of images

ICLR 2023top-25%

Deep neural networks can learn powerful prior probability models for images, as evidenced by the high-quality generations obtained with recent score-based diffusion methods. But the means by which these networks capture complex global statistical structure, apparently without suffering from the curs…

Stochastic Solutions for Linear Inverse Problems using the Prior Implicit in a Denoiser

NeurIPS 2021poster

Deep neural networks have provided state-of-the-art solutions for problems such as image denoising, which implicitly rely on a prior probability model of natural images. Two recent lines of work – Denoising Score Matching and Plug-and-Play – propose methodologies for drawing samples from this implic…

Robust And Interpretable Blind Image Denoising Via Bias-Free Convolutional Neural Networks

ICLR 2020poster

We study the generalization properties of deep convolutional neural networks for image denoising in the presence of varying noise levels. We provide extensive empirical evidence that current state-of-the-art architectures systematically overfit to the noise levels in the training set, performing ver…
