Multiple kernel nonnegative matrix factorization

Kernel nonnegative matrix factorization (KNMF) is a recent kernel extension of NMF, where matrix factorization is carried out in a reproducing kernel Hilbert space (RKHS) with a feature mapping φ(·). Given a data matrix X ∈ ℝ m×n , KNMF seeks a decomposition, φ(X) ≈ UV T , where the basis matrix tak... View More
