Abstract

This report introduces a novel Variable-Separation (VS) method for model order reduction, designed to simplify high-dimensional systems by effectively decoupling spatial, temporal, and parametric variables. The proposed approach is further extended to a broad class of stochastic partial differential equations (PDEs)，thereby significantly enhancing computational efficiency compared to conventional techniques.  Numerical experiments confirm its accuracy, robustness, and scalability.
