Probabilistic simplex component analysis
This study presents PRISM, a probabilistic simplex component analysis approach to
identifying the vertices of a data-circumscribing simplex from data. The problem has a rich …

Hyperspectral Unmixing Under Endmember Variability: A Variational Inference Framework
This work proposes a variational inference (VI) framework for hyperspectral unmixing in the
presence of endmember variability (HU-EV). An EV-accounted noisy linear mixture model …

Multilayer Simplex-structured Matrix Factorization for Hyperspectral Unmixing with Endmember Variability
J Liu, Y Li, WK Ma - arxiv preprint arxiv:2401.14592, 2024 - arxiv.org
Given a hyperspectral image, the problem of hyperspectral unmixing (HU) is to identify the
endmembers (or materials) and the abundance (or endmembers' contributions on pixels) …
