Alternatively, various computational approaches, have proven rigorous and successful, but still suffer from being generally resource-intensive and occasionally difficult to interpret. Particularly for classes of systems that can be described by partial differential equations, such as for example multi-component crystalline solids undergoing mechanical deformations, and changes in chemical potential, high-fidelity solutions generally contain up to tens of millions of degrees of freedom. New methods must, therefore, be developed that represent this information in a lower-dimensional space, allowing for more efficient, and intuitive computations.
In this talk, I will be introducing a novel graph-theoretic approach for reduced-order modelling of a wide class of systems, allowing for more efficient and effective data-driven simulations. Concepts in graph theory will be introduced, including a rigorous non-local discrete calculus, and I will describe how states of a system and their relationships can be represented using this formalism. I will then discuss the numerical methods for computing a reduced-order model for quantities of interest and will show some preliminary results, indicating the validity and possible exciting future applications of this general framework.",https://events.umich.edu/event/75632,"Off Campus Location",,"Join us using the following virtual Bluejeans link: https://bluejeans.com/937279882",,"Free
