Active Manifolds: A non-linear analogue to Active Subspaces

1 code implementation30 Apr 2019 Robert A. Bridges, Anthony D. Gruber, Christopher Felder, Miki Verma, Chelsey Hoff

Overall, AM represents a novel technique for analyzing functional models with benefits including: reducing $m$-dimensional analysis to a 1-D analogue, permitting more accurate regression than AS (at more computational expense), enabling more informative sensitivity analysis, and granting accessible visualizations(2-D plots) of parameter sensitivity along the AM.

Dimension Reduction Using Active Manifolds

This project was inspired by an approach known as Active Subspaces, which works by linearly projecting to a linear subspace where the function changes most on average.
