One-Shot Transfer Learning for Nonlinear ODEs

no code implementations25 Nov 2023 Wanzhou Lei, Pavlos Protopapas, Joy Parikh

We introduce a generalizable approach that combines perturbation method and one-shot transfer learning to solve nonlinear ODEs with a single polynomial term, using Physics-Informed Neural Networks (PINNs).

Efficient Natural Gradient Descent Methods for Large-Scale PDE-Based Optimization Problems

no code implementations13 Feb 2022 Levon Nurbekyan, Wanzhou Lei, Yunan Yang

We propose efficient numerical schemes for implementing the natural gradient descent (NGD) for a broad range of metric spaces with applications to PDE-based optimization problems.
