Automated detection of corrosion in used nuclear fuel dry storage canisters using residual neural networks
Theodore Papamarkou, Hayley Guy, Bryce Kroencke +8
Nondestructive evaluation methods play an important role in ensuring component integrity and safety in many industries. Operator fatigue can play a critical role in the reliability…
A distributed active subspace method for scalable surrogate modeling of function valued outputs
Hayley Guy, Alen Alexanderian, Meilin Yu
We present a distributed active subspace method for training surrogate models of complex physical processes with high-dimensional inputs and function valued outputs. Specifically,…
Derivative-based global sensitivity analysis for models with high-dimensional inputs and functional outputs
Helen L. Cleaves, Alen Alexanderian, Hayley Guy +2
We present a framework for derivative-based global sensitivity analysis (GSA) for models with high-dimensional input parameters and functional outputs. We combine ideas from deriva…
Subspace-based dimension reduction for chemical kinetics applications with epistemic uncertainty
M. Vohra, A. Alexanderian, H. Guy +1
We focus on an efficient approach for quantification of uncertainty in complex chemical reaction networks with a large number of uncertain parameters. Parameter dimension reduction…
