SpectralUnmix: A Torch-Based Regularized Non-negative Matrix Factorization
Abstract
SpectralUnmix is an R package for smooth non-negative spectral unmixing of hyperspectral and astronomical IFU data. The package fits a regularized factorization model and provides helpers for reshaping cubes, reconstructing components, and preserving cube-side metadata through fitted outputs.
