Our work stood out for its critical focus on AI safety, with the jury emphasizing: "The rapid development of AI sometimes comes at the expense of public safety. Highlighting the risks of data non-confidentiality is a crucial step in establishing ethical guidelines."

In a nutshell, the method works by iteratively refining and merging scenario sets to obtain tightened bounds. Convergence is guaranteed over a finite number of iterations, and we experimentally measure very significant speed-ups over direct solution approaches.

Last week was my first time in a radio studio, joining @matthieudugal.bsky.social & Moteur de Recherche on Radio Canada. What an experience! The vibe was fantastic & there's something so exciting about chatting with the columnists and sharing cool science facts🎙️🤩 ici.radio-canada.ca/ohdio/premie...
