This repository contains the Python based implementation of the Multivariate Sensitivity Adaptive (MVSA) Polynomial Chaos Expansion (PCE) method, which is described in the paper "Multivariate sensitivity-adaptive polynomial chaos expansion for high-dimensional surrogate modeling and uncertainty quantification" by D. Loukrezis, E. Diehl, and H. De Gersem, available at https://doi.org/10.1016/j.apm.2024.115746. Please cite this work, in case you use and/or refer to the MVSA PCE method and/or related software.
