Dear All,
You are cordially invited to Institute for Advanced Study 3rd Lecture jointly organized by Institute for Advanced Study (IAS) and Research Center for Mathematics (RCM). The guest speaker is Prof. Luca Biferale, he is a full professor (since 2014) of Theoretical Physics, Mathematical and Numerical Modelling, Dept. Physics, University of Rome Tor Vergata, Italy. He will introduce "Generative AI for Lagrangian and Eulerian Turbulence".
Please find the event details below.
Topic: Generative AI for Lagrangian and Eulerian Turbulence
Speaker: Prof. Luca Biferale
Date: 11 March 2025 (Tuesday)
Time: 14:00-16:00
Venue: T2-202
Language: English
Speaker Introduction:
Luca Biferale, Full Professor of Theoretical Physics at the Venue Physics Department of the University of Rome"Tor Vergata". He is author of more than 250 scientific articles in the field of turbulence, micro-, nano-fluidies, and dynamical systems using mainly data-driven and equation-informed numerical methods. He has been elected a fellow of Euromech and the American Physical Society (APS) and has served on the board of editors of many scientific journals including Physical Review Letter. He was twice awarded the prestigious Advanced Grant from the European Research Council.
Abstract:
We present a stochastic method for generating and reconstructing complex signals along the trajectories of small objects passively advected by turbulent flows [1]. Our approach makes use of generative Diffusion Models, a recently proposed data-driven machine learning technique. We show applications to 3D tracers and inertial particles in highly turbulent flows, 2D trajectories from NOAA’s Global Drifter Program and dynamics of charged particles in astrophysics. Supremacy against linear decomposition and Gaussian Regression Processes is analyzed in terms of statistical and point-wise metrics concerning intermittency and multi-scale properties. Preliminary results concerning generalizability and model collapse will also be discussed.
