NMF/NTF-based methods applied for user-guided audio source separation: An overview

Recently, user-guided or user-assisted audio separation, which exploits the auxiliary information of sources provided by users, is a new direction in audio source separation. Nonnegative matrix or tensor factorization (NMF/NTF) is one of the promising classes of approaches to address this task. In this paper, we present a survey of recent developments in user-guided source separation approaches based on NMF/NTF and illustrate various ways for incorporating the provided knowledge from user.
