A Bayesian Framework for Built-in Input Dimension Reduction for Gaussian Process Modeling

Eric Herrison Gyamfi, Emily L. Kang, Bledar A. Konomi, Guang Lin

Gaussian process (GP) modeling is widely used in computational science and engineering. However, fitting a GP to high-dimensional inputs remains challenging due to the curse of dimensionality. While various methods have been proposed to reduce input dimensionality, they typically…

A Hyperbolic Neural Closure for M1 Radiation Transfer

Bongseok Kim, Jiahao Zhang, Johannes Krotz, Dinshaw Balsara, Ryan McClarren, Guang Lin

In radiation transfer simulations, an M1 method achieves substantial computational savings by replacing the full angular transport equation with a low-order moment system. Because this reduced system is not closed, a closure model is required to represent the unknown higher-order…
