Summary

The upcoming CASIS 2023 workshop on August 2–3, 2023, aims to delve into the existing opportunities and challenges pertinent to the signal and image sciences community. The event intends to foster a productive exchange of cutting-edge technological advancements and recent developments, stimulating interesting discussions and bringing the community together. In order to augment technical exchanges between attendees, intermediate results from ongoing projects and recent conference papers are strongly encouraged for submission. Attendees will have the opportunity to discuss the presentations with the authors in more detail in our poster sessions for which we provide coffee and snacks. This event is open to all engineers, scientists, and students who hold an interest in signal and image sciences.

The workshop is a two-day event and will be held in-person at the Livermore Valley Open Campus (LVOC), B643 R1400, requires pre-registration before July 27, 2023, and non-LLNL employees require a valid photo ID to attend. Interested authors can submit their proposals until June 28, 2023. Registration is free and we will provide lunch, coffee, and snacks on both workshop days.

For general questions about the workshop, contact Ruben Glatt. For questions about the program, please reach out to the respective Program Chair of the track you want to present in.

Workshop Tracks

This year’s workshop will feature the following tracks, moderated by the Program Chairs:

• AI/Machine Learning [Hiranmayi Ranganathan, Shusen Liu]
• Quantum Computing / Quantum Sensing [Yaniv Rosen]
• Non-Destructive Evaluation [K. Aditya Mohan]
• National Ignition Facility [Kelli Humbird]
• Geophysical Signal Processing [Dennise Templeton, Qingkai Kong]

Invited Speakers

Join us for an engaging workshop featuring three distinguished speakers. Brian Spears from the Lawrence Livermore National Laboratory will take you on a journey into the Fusion Ignition: Science in Support of a Historic Breakthrough, while Prof. Dr. Lei Li from the University of California Santa Barbara expands your mind with the game-changing power of Large Language Models. Finally, we dive into the enigmatic world of quantum computing and hear about Control and readout of superconducting qubits with David Pappas from the University of Colorado Boulder.
