An optimal pairwise merge algorithm improves the quality and consistency of nonnegative matrix factorization
Youdong Guo, Timothy E. Holy
Non-negative matrix factorization (NMF) is a key technique for feature extraction and widely used in source separation. However, existing algorithms may converge to poor local mini…
