Fall 2024
- Representation/Manifold Learning: Learned Representations
- Friday, October 18, 2024, 2:00pm–3:00pm
- Led by Alex Gagliano and Sam Bright-Thonney (IAIFI Fellows)
- Many of the recent successes in AI rely on the manifold hypothesis: that most high-dimensional data lie on a lower-dimensional manifold. From transfer to contrastive learning to foundation modeling, significant effort has been devoted to methods to efficiently find and map input data to this latent space. In this Thematic Discussion Session, we’ll hear from three distinguished speakers on extracting meaningful latent representations from data from the physical sciences: Aizhan Akhmetzhanova (Self-Supervised Learning for Data Compression and Inference in Cosmology), Nate Woodward, (Product Manifold Machine Learning for Physics) and David Baek, (GenEFT: Physics-Inspired Theory of Representation Learning). After three 10-minute lightning talks, we’ll have a 30 minute open discussion/Q&A session to explore the major challenges and opportunities in this field. We encourage attendees to come with questions and insights from their own work!

- IAIFI-UMass Boston Workshop: Partnership for research and training in QUantum, Artificial intelligence, Non-equilibrium physics Theory and Applications (QUANTA)
- Friday, November 15, 2024, 2:00pm–5:00pm
- Rahul Kulkarni, UMass Boston and others
- In 2024, IAIFI launched a research partnership with UMass Boston. The partnership is focused on developing physics-informed reinforcement learning approaches to solve problems in quantum science and technology; in particular, developing novel approaches for entropy-regularized RL to advance current research in quantum systems and applying entropy-regularized RL tools to solve optimization problems in quantum science and technology. The event will kick off with presentations from UMass Boston researchers on this topic. We invite IAIFI researchers with research relevant to this project to sign up to give lightning talks as well (~10 minutes each). Sign up to give a lightning talk.

Spring 2024
- Generative Modeling
- Friday, April 19, 2024, 2:00pm–3:00pm
- Led by Carol Cuesta-Lazaro and Denis Boyda (IAIFI Fellows)
- In this thematic discussion, we will present three distinguished speakers who will deliver 7-minute lightning talks: Ziming Liu (Generating Generative Models from Physics), Ameya Daigavane (Symphony: Improving Autoregressive Models for 3D Molecule Generation), Ge Yang (Peeking Through A Pinhole: Foundation Priors for Robot Perception). After the lightning talks, a panel discussion on generative modeling will be conducted. The discussion will focus on open questions about applying generative modeling in physics and incorporating physical principles into generative modeling techniques. Attendees are encouraged to bring questions from their respective fields to enrich the discussion.
- Talk Slides (for IAIFI members only)
- Uncertainty Quantification
- Friday, February 16, 2024, 2:00pm–3:00pm
- Led by Gaia Grosso and Jessie Micallef (IAIFI Fellows)
- The discussion will begin with a few flash presentations (~5 min each) by current IAIFI colleagues working on this subject. Gaia and Jessie will then lead a guided discussion to collect uncertainty quantification and robustness challenges across IAIFI and discuss pathways towards potential solutions and future work. Through this discussion, the aim is to bring together IAIFI researchers to learn from each other’s experience, build connections and possibly research collaborations–you are encouraged to join the discussion no matter your research interests or background!
