(a) and (b) show a segment that belongs to a piano signal in time and TF representations, respectively. Applying NMF to the TF matrix, we extract 15 base and coefficient vectors which are depicted in (c) and (d), respectively.Time representationTF representationBase vectors decomposed using NMF MD techniqueCoefficient vectors decomposed using NMF MD technique
