Our theoretical modeling of complex nuclear phenomena typically contains superfluous information for quantities of interest. Model order reduction (MOR) refers to powerful techniques that enable us to systematically reduce the complexity. These techniques enable emulators, which are low-dimensional surrogate models capable of rapidly and reliably approximating high-fidelity models, making practical otherwise impractical calculations. A particularly fertile area for new emulators is Bayesian uncertainty quantification. I will discuss recent developments in emulators for low-energy nuclear physics while highlighting the broader context of MOR technology.
The speaker for this event will lead the meeting remotely. All interested graduate students and faculty are invited to attend by convening in the INT Seminar Room (C-421).
Participants are also welcome to join via Zoom. Zoom link will be available via announcement email, or by contacting: gsj6[at]uw.edu or prau[at]uw.edu
