HypoSVI- Earthquake Hypocentre Inversion With Stein Variational Inference and Physics Informed Neural Networks

Alan Turing Institute via YouTube

Overview

Explore cutting-edge applications of physics-informed deep learning techniques in environmental and physical sciences through this 50-minute talk by Jonathan Smith from the Alan Turing Institute. Delve into three main topics: Physics Informed Neural Networks (PINNs) for solving the Eikonal Equation, probabilistic inversion in PINNs for earthquake location applications, and Neural Operators for in-ice navigation. Learn how EikoNet, a PINN-based solution, tackles the Eikonal Equation for quick travel-time calculations in geological models. Discover how the differentiability of PINNs enables the use of Stein Variational Gradient Descent for rapid earthquake location posterior distribution estimation. Gain insights into preliminary work on Neural Operators for optimizing travel-time in various sea-ice conditions to minimize fuel usage and risk in navigation.
