Elliptical Basis Function interpolation library for smooth fits to scattered data
EBF tackles the challenge of interpolating high‑dimensional engineering data where traditional RBF assumes a uniform Euclidean distance. Each node learns its own positive‑definite ellipsoid, allowing stretch and rotation to capture variable interactions. The package provides multiple basis functions, robust loss options, automatic scaling, and visual diagnostics, making it useful for engineers and scientists needing accurate surrogate models. Compared to standard RBF, EBF achieves lower error with fewer nodes, especially as dimensionality grows.
