Learning Differential Equations that are Easy to Solve

NeurIPS 2020poster

Differential equations parameterized by neural networks become expensive to solve numerically as training progresses. We propose a remedy that encourages learned dynamics to be easier to solve. Specifically, we introduce a differentiable surrogate for the time cost of standard numerical solvers, usi…

FFJORD: Free-Form Continuous Dynamics for Scalable Reversible Generative Models

ICLR 2019oral

A promising class of generative models maps points from a simple distribution to a complex distribution through an invertible neural network. Likelihood-based training of these models requires restricting their architectures to allow cheap computation of Jacobian determinants. Alternati…

Neural Ordinary Differential Equations

NeurIPS 2018oral

We introduce a new family of deep neural network models. Instead of specifying a discrete sequence of hidden layers, we parameterize the derivative of the hidden state using a neural network. The output of the network is computed using a blackbox differential equation solver. These continuous-depth…
