Self-Supervised Learning from Noisy and Incomplete Data
Many important problems in science and engineering involve inferring a signal from noisy and/or incomplete observations, where the observation process is known. Historically, this problem has been tac...

☀️ Just wrapped up the DeepInverse Hackathon! We had 30+ imaging scientists from all over the world coding during 3 days next to the beautiful Calanques in Marseille, France. It was a great moment to meet new people, discuss science, and code new imaging algorithms!

🚀🚀 Reconstruct-Anything-Model: A single model to rule all imaging tasks! We challenge current beliefs and show that a single U-Net can obtain impressive performance across a wide variety of tasks, **without** relying on expensive iterative schemes such as unrolling, PnP, diffusion

Deriving Tweedie's formula from SURE let's you also derive other interesting generalisations, such as a formula that doesn't require knowledge about the noise level, and it can be generalized well beyond isotropic gaussian noise.
