Simulation results to show how decompositions vary with differing numbers of underlying sources. The dotted vertical line shows the number of underlying sources in each case (from left to right: K = 25, 50, 75). Results are shown from ICA and NMF decompositions, in orange and blue, respectively. σ2 = 0.05 and a = 0.1 for NMF.
