Amortized Finite Element Analysis for Fast PDE-Constrained Optimization

1 code implementation ICML 2020 Tianju Xue, Alex Beatson, Sigrid Adriaenssens , Ryan Adams

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.

Hybrid full-field thermal characterization of additive manufacturing processes using physics-informed neural networks with data

1 code implementation15 Jun 2022 Shuheng Liao, Tianju Xue, Jihoon Jeong, Samantha Webster, Kornel Ehmann, Jian Cao

Specifically, partially observed temperature data measured from an infrared camera is combined with the physics laws to predict full-field temperature history and to discover unknown material and process parameters.

Transfer Learning

Learning the nonlinear dynamics of soft mechanical metamaterials with graph networks

1 code implementation24 Feb 2022 Tianju Xue, Sigrid Adriaenssens, Sheng Mao

We verify the accuracy of our machine learning approach against several representative numerical examples.

Amortized Synthesis of Constrained Configurations Using a Differentiable Surrogate

1 code implementation NeurIPS 2021 Xingyuan Sun, Tianju Xue, Szymon Rusinkiewicz, Ryan P. Adams

We compare our approach to direct optimization of the design using the learned surrogate, and to supervised learning of the synthesis problem.
