Abstract: We study the notion of (additive) separability of a function of several variables with respect to a hypergraph (H-graph). We prove the existence of a unique minimal H-graph with respect to ...

Abstract: In the field of hyperspectral unmixing (HU), to decompose mixed pixels into pure substances and their corresponding fractional abundances, the (hyper)graph constrained (D) nonnegative matrix ...
