"HOT-AI" Workshop Recap:
Exploring the Frontiers of AI and Optimization
|
|
|
The HOT-AI: Horizons of Optimization for AI Workshop, hosted by TILOS on April 17-18, 2025 at UC San Diego’s Halıcıoğlu Data Science Institute, brought together a vibrant community of researchers including students and postdoctoral scholars to explore the rapidly evolving interplay between optimization and AI.
Over two days, attendees engaged with a lineup of distinguished speakers from institutions including Caltech, UC Berkeley, Stanford, USC, UCLA, UT Austin, and more. Sessions ranged from foundational theory to emerging applications, spotlighting the dual lens of optimization for AI systems and AI for solving complex optimization problems.
Recordings of all presentations are available online—see titles and links below.

Researchers at UC San Diego and other institutions are working on a way to make a type of artificial intelligence (AI) called diffusion models more efficient and widely applicable. Currently, diffusion models work by making small, incremental changes to input data, allowing the model to learn complex patterns and relationships—a process that can be slow and limited in application. So Yian Ma, an assistant professor at UC San Diego’s Halıcıoğlu Data Science Institute, and his research colleagues have developed a new approach that allows for larger jumps in between steps, making the process faster and more flexible. Read the full story in UC San Diego Today.
