Rare Event Probability Learning by Normalizing Flows

no code implementations29 Oct 2023 Zhenggqi Gao, Dinghuai Zhang, Luca Daniel, Duane S. Boning

Next, it estimates the rare event probability by utilizing importance sampling in conjunction with the last proposal.

KirchhoffNet: A Circuit Bridging Message Passing and Continuous-Depth Models

no code implementations24 Oct 2023 Zhengqi Gao, Fan-Keng Sun, Duane S. Boning

Moreover, we justify that irrespective of the number of parameters within a KirchhoffNet, its forward calculation can always be completed within 1/f seconds, with f representing the hardware's clock frequency.

NeurOLight: A Physics-Agnostic Neural Operator Enabling Parametric Photonic Device Simulation

1 code implementation19 Sep 2022 Jiaqi Gu, Zhengqi Gao, Chenghao Feng, Hanqing Zhu, Ray T. Chen, Duane S. Boning, David Z. Pan

In this work, for the first time, a physics-agnostic neural operator-based framework, dubbed NeurOLight, is proposed to learn a family of frequency-domain Maxwell PDEs for ultra-fast parametric photonic device simulation.

FreDo: Frequency Domain-based Long-Term Time Series Forecasting

no code implementations24 May 2022 Fan-Keng Sun, Duane S. Boning

Finally, we validate that the frequency domain is indeed better by comparing univariate models trained in the frequency v. s.

Adjusting for Autocorrelated Errors in Neural Networks for Time Series

1 code implementation NeurIPS 2021 Fan-Keng Sun, Christopher I. Lang, Duane S. Boning

A common assumption in training neural networks via maximum likelihood estimation on time series is that the errors across time steps are uncorrelated.

Variational inference formulation for a model-free simulation of a dynamical system with unknown parameters by a recurrent neural network

no code implementations2 Mar 2020 Kyongmin Yeo, Dylan E. C. Grullon, Fan-Keng Sun, Duane S. Boning, Jayant R. Kalagnanam

Unlike the classical variational inference, where a factorized distribution is used to approximate the posterior, we employ a feedforward neural network supplemented by an encoder recurrent neural network to develop a more flexible probabilistic model.
