Karen E. Willcox
Multifidelity Proper Orthogonal Decomposition
Symposium
Event
Documents and Media Download the support material Abstract Proper orthogonal decomposition (POD) is widely used to compute a low-dimensional basis that underpins a subsequent dimension reduction or reduced-order modeling step. POD is data-driven in the …

David Ryckelynck
Self-Supervised Machine Learning of ROM-nets for the Mechanics of Materials
Symposium
Event
Documents and Media Download the support material Abstract We propose a general framework for projection-based model order reduction using self-supervised machine learning [1]. For parametric elliptic equations, this approach is theoretically grounded in …
