Voice-voice separation score (cross-domain). Average and standard deviation of SDR, SIR, and SAR scores for voice BSS, in the cross-domain setting where training spectrograms have fewer frequencies than testing spectrograms. The scores are for NMF with optimal transport (dark blue), optimal transport with our generalized filter (light blue), Kullback-Leibler (green), Itakura-Saito (brown), or Euclidean (yellow) NMF
