Universal Approximation of Nonlinear Operators and Their Derivatives
Derivative-Informed Operator Learning (DIOL), i.e. learning a (nonlinear) operator and its derivatives, is an open research frontier at the foundations of the influential field of …

Breakeven complexity: A new perspective on neural partial differential equation solvers
Neural surrogate solvers of partial differential equations (PDEs) promise dramatic speedups over numerical methods, especially in scenarios requiring many solves. However, current …

Amortized Energy-Based Bayesian Inference
We consider amortized Bayesian inference for nonlinear inverse problems in settings where only samples from the joint distribution of parameters and observations are available. Cla…
