An Interpretable Surrogate Model with an Enhanced Multivariance Product Representation Support and a Neural Residual: Dimension-Independent Accuracy on Product Structure and a Diagnostic for Real Data

High-dimensional model representation (HDMR) gives a surrogate that is interpretable by construction: with an orthonormal basis, its component functions translate directly into variance-based Sobol' sensitivity indices. The established HDMR surrogates, however, expand the respons...
