Functional PCA and deep neural networks-based Bayesian inverse uncertainty quantification with transient experimental data
COMPUTER METHODS IN APPLIED MECHANICS AND ENGINEERING, 420.
author keywords: Bayesian inverse UQ; Functional alignment; Functional PCA; Neural networks
TL;DR:
This work focuses on developing an inverse UQ process for time-dependent responses, using functional principal component analysis (PCA) and deep neural network (DNN)-based surrogate models, and shows an improvement in reducing the dimension of the TRACE transient simulations.
