This workshop will serve as a hackathon to develop DeepInverse https://deepinv.github.io/, an open-source PyTorch library for solving imaging inverse problems with deep learning. DeepInverse aims to cover most of the steps in modern imaging pipelines, from the definition of the forward sensing operator to the training of reconstruction networks in a supervised or self-supervised way. The library is the recipient of the obtained the 2024 documentation award at the French Open Source Software for Science Awards https://www.ouvrirlascience.fr/deepinverse/, and is part of the official PyTorch Ecosystem https://pytorch.org/blog/deepinverse-joins-pytorch-ecosystem/ (the leading open-source deep learning library) since November 2025, and is also part of the Inria’s P16 AI program https://p16.inria.fr/fr/ since March 2026.
The goal of the workshop is to bring together contributors to the library across Europe to develop this open-source project further and consolidate a growing community of researchers using the library in their research projects. The workshop will focus on the addition of new functionalities, in particular new advanced imaging operators, such as positron emission tomography and single-photon emission computed tomography, a general framework for diffusion methods for inverse problems, and new benchmarks for comparing state-ofthe-art learning-based image reconstruction methods. The overarching goal of the workshop is to continue consolidating the library as a default tool for solving inverse problems with deep learning across various research communities.
