Amortized Synthesis of Constrained Configurations Using a Differentiable Surrogate

NeurIPS 2021spotlight

In design, fabrication, and control problems, we are often faced with the task of synthesis, in which we must generate an object or configuration that satisfies a set of constraints while maximizing one or more objective functions. The synthesis problem is typically characterized by a physical proce…

Amortized Finite Element Analysis for Fast PDE-Constrained Optimization

ICML 2020poster

Optimizing the parameters of partial differential equations (PDEs), i.e., PDE-constrained optimization (PDE-CO), allows us to model natural systems from observations or perform rational design of structures with complicated mechanical, thermal, or electromagnetic properties. However, PDE-CO is often…

Learning Composable Energy Surrogates for PDE Order Reduction

NeurIPS 2020oral

Meta-materials are an important emerging class of engineered materials in which complex macroscopic behaviour--whether electromagnetic, thermal, or mechanical--arises from modular substructure. Simulation and optimization of these materials are computationally challenging, as rich substructures nece…
