Bites of Foundation Models for Science: Product Manifold Machine Learning for Physics

November 20, 2024

Talk, Bites of Foundation Models for Science - Physics-inspired representaions, MIT

Particle jets exhibit tree-like structures through stochastic showering and hadronization. The hierarchical nature of these structures aligns naturally with hyperbolic space, a non-Euclidean geometry that captures hierarchy intrinsically. Drawing upon the foundations of geometric learning, we introduce hyperbolic transformer models tailored for tasks relevant to jet analyses, such as classification and representation learning. Through jet embeddings and jet tagging evaluations, our hyperbolic approach outperforms its Euclidean counterparts. These findings underscore the potential of using hyperbolic geometric representations in advancing jet physics analyses.

IAIFI Thematic Discussion on Representation and Manifold Learning: Product Manifold Machine Learning for Physics

October 18, 2024

Talk, IAIFI Thematic Discussion on Representation and Manifold Learning., MIT

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!
