Listening to the Noise: Blind Denoising with Gibbs Diffusion

1 code implementation29 Feb 2024 David Heurtel-Depeiges, Charles C. Margossian, Ruben Ohana, Bruno Régaldo-Saint Blancard

Assuming arbitrary parametric Gaussian noise, we develop a Gibbs algorithm that alternates sampling steps from a conditional diffusion model trained to map the signal prior to the family of noise distributions, and a Monte Carlo sampler to infer the noise parameters.

Bayesian Inference Denoising

Simulation-based stacking

no code implementations25 Oct 2023 Yuling Yao, Bruno Régaldo-Saint Blancard, Justin Domke

Simulation-based inference has been popular for amortized Bayesian computation.

Removing Dust from CMB Observations with Diffusion Models

no code implementations25 Oct 2023 David Heurtel-Depeiges, Blakesley Burkhart, Ruben Ohana, Bruno Régaldo-Saint Blancard

We investigate diffusion-based modeling of the dust foreground and its interest for component separation.

Statistical Component Separation for Targeted Signal Recovery in Noisy Mixtures

1 code implementation26 Jun 2023 Bruno Régaldo-Saint Blancard, Michael Eickenberg

In the case of 1), we show that our method better recovers the descriptors of the target data than a standard denoising method in most situations.
