I think it only mentions ICA/NMF to say that they generally aren't applied to time-domain signals, which are not non-negative and have phase as a confounding factor.
Here's another intriguing (very different) recent paper on time-domain source separation: https://arxiv.org/abs/1810.12679 https://arxiv.org/abs/1810.12679
- jordipons_mtg 8y agoI'm Jordi Pons, one of the coauthors of the paper. You both are right! We basically mention ICA/sparse coding as prior work on waveform front-ends for source separation. Our method is supervised, and we did not explore the unsupervised learning approach. However, some people are doing that! Check S. Venkataramani and P. Smaragdis work! https://scholar.google.es/citations?user=hCSSNZwAAAAJ&hl=es&oi=sra https://scholar.google.es/citations?user=hCSSNZwAAAAJ&hl=es&... Although we did our best via comparing against DeepConvSep and Wave-U-Net, I agree that it would be useful to properly benchmark all that!
