Workshop Description

Learning-based methods, and in particular deep neural networks, have emerged as highly successful and universal tools for image and signal recovery and restoration. They achieve state-of-the-art results on tasks ranging from image denoising, image compression, and image reconstruction from few and noisy measurements. They are starting to be used in important imaging technologies, for example in GEs newest computational tomography scanners and in the newest generation of the iPhone. They are also used in inverse problems beyond imaging, including for solving inverse problems arrising in communications, signal processing, and even on non-Euclidean data suchs as graphs.

The field has a range of theoretical and practical questions that remain unanswered, including questions about guarantees, robustness, architectural design, the role of learning, domain specific applications, and more. This virtual workshop aims at bringing together theoreticians and practitioners in order to chart out recent advances and discuss new directions in deep learning-based approaches for solving inverse problems in the imaging sciences and beyond.

How to attend the workshop

The workshop is livestreamed at the NeurIPS workshop webpage. To access this website you need to register for the conference at and be logged in.

The livestream will play the talks, and each of the talks is followed by a live discussion. You can attend the live discussion either through the live stream or you can join the zoom session. Questions should be asked either through rocketchat or in the chat function in the zoom session, and a co-organizer will moderate.

During the designated discussion sessions you can talk to the respective speakers in
