Multifidelity linear regression for scientific machine learning from scarce data

no code implementations13 Mar 2024 Elizabeth Qian, Anirban Chaudhuri, Dayoung Kang, Vignesh Sella

Machine learning (ML) methods, which fit to data the parameters of a given parameterized model class, have garnered significant interest as potential methods for learning surrogate models for complex engineering systems for which traditional simulation is expensive.

Learning High-Dimensional Parametric Maps via Reduced Basis Adaptive Residual Networks

2 code implementations14 Dec 2021 Thomas O'Leary-Roseberry, Xiaosong Du, Anirban Chaudhuri, Joaquim R. R. A. Martins, Karen Willcox, Omar Ghattas

We propose a scalable framework for the learning of high-dimensional parametric maps via adaptively constructed residual network (ResNet) maps between reduced bases of the inputs and outputs.

Certifiable Risk-Based Engineering Design Optimization

no code implementations13 Jan 2021 Anirban Chaudhuri, Boris Kramer, Matthew Norton, Johannes O. Royset, Karen Willcox

CRiBDO is contrasted with reliability-based design optimization (RBDO), where uncertainties are accounted for via the probability of failure, through a structural and a thermal design problem.

mfEGRA: Multifidelity Efficient Global Reliability Analysis through Active Learning for Failure Boundary Location

no code implementations6 Oct 2019 Anirban Chaudhuri, Alexandre N. Marques, Karen E. Willcox

The method builds on the Efficient Global Reliability Analysis (EGRA) method, which is a surrogate-based method that uses adaptive sampling for refining Gaussian process surrogates for failure boundary location using a single-fidelity model.
