MATLAB Toolbox: Nonnegative Matrix Factorization with Volume Constraints

Morten Arngren, Mikkel N. Schmidt, Jan Larsen

AbstractThe MATLAB toolbox consists maximum aposteriori NMF algorithm with a volume and sum-to-one constraint. The NMF-Vol includes minimum volume constraint (Miao and Qi), parallelepiped volume, and Euclidian distance based volume constraint.
