Michael Perlmutter - The Geometric Scattering Transform for High-dimensional Data Analysis @IPAMUCLA

Uploaded February 2026 | Updated September 2026, 3 weeks ago

Recorded 26 February 2026. Michael Perlmutter of Boise State University presents "The Geometric Scattering Transform for High-dimensional Data Analysis" at IPAM's Mathematics of Cancer: Open Mathematical Problems Workshop.
Abstract: Modern single-cell datasets often are often extremely high-dimensional which presents challenges for traditional methods of data analysis. However, such data sets often have a hidden, low-dimensional underlying structure where, for example, gene coordinate and redundancy may cause the data to lie upon a comparatively low-dimensional manifold. This motivates methods which find and/or utilize this hidden structure.
My talk will focus on methods from geometric deep learning which approximate the underlying data manifold via a graph and use wavelet-based graph neural networks, based on the geometric scattering transform. We show that these methods capture the underlying data geometry and are able to capture both the local and global structure of the data.

$Jakob Kottman - Holistic Approaches to Quantum Computation: Software and Algorithmics Recorded 19 February 2026. Jakob Kottman of Universität Augsburg presents Holistic Approaches to Quantum Computation: Software and Algorithmics at IPAMs Bridging the Gap Between NISQ and FTQC Workshop. Abstract: A significant fraction of present-day quantum algorithmic research relies on numerical procedures to gain further insights and explore new applications. Here, one typically deals with numerous interconnected classical and quantum algorithmic components. In this talk, I will illustrate how quantum algorithmics and scientific software development can form a powerful symbiosis to tackle problems in electronic structure Learn more online at: https://www.ipam.ucla.edu/programs/workshops/bridging-the-gap-between-nisq-and-ftqc/$

$Hong Qin - Machine Learning of Local Confinement & Transport from Intl Multi-Tokamak Confinement DB Recorded 06 May 2026. Hong Qin of Princeton University presents Machine Learning of Local Confinement and Transport from the International Multi-Tokamak Confinement Profile Database at IPAMs Fusion Device Design and Engineering Workshop. Abstract: With the accelerated push toward commercial magnetic DT fusion, tritium self-sufficiency has emerged as a critical challenge. One of the key quantities governing tritium self-sufficiency is the tritium burn fraction, which depends critically on particle confinement time in magnetically confined plasmas. Theoretically, particle confinement is controlled by transport coefficients that are functions of plasma and device parameters local to each flux surface. Much of the historical effort to characterize these coefficients has relied on empirical scaling laws, typically developed for individual devices. We present a Gaussian process regression study of local confinement and transport coefficients based on the 2008 public release of the International Multi-Tokamak Confinement Profile Database, which includes 344 discharges from TFTR, JET, DIII-D, Tore Supra, T-10, ITER simulations, JT-60U, ASDEX Upgrade, RTP, MAST, Alcator C-Mod, FTU, and TEXTOR. Preliminary results will be discussed, together with their implications for cross-device confinement modeling.
