The Vanishing Gradient Problem for Stiff Neural Differential Equations
Colby Fronk, Linda Petzold
Gradient-based optimization of neural differential equations and other parameterized dynamical systems fundamentally relies on the ability to differentiate numerical solutions with…
Training Stiff Neural Ordinary Differential Equations with Explicit Exponential Integration Methods
Colby Fronk, Linda Petzold
Stiff ordinary differential equations (ODEs) are common in many science and engineering fields, but standard neural ODE approaches struggle to accurately learn these stiff systems,…
Performance Evaluation of Single-step Explicit Exponential Integration Methods on Stiff Ordinary Differential Equations
Colby Fronk, Linda Petzold
Stiff systems of ordinary differential equations (ODEs) arise in a wide range of scientific and engineering disciplines and are traditionally solved using implicit integration meth…
