... esting condition, while the −5 dB level was excluded from training. Thus, the multicondition training, as well as training with BA or ST noise, involves the union of training data corresponding ... postprocessing of the NMF activations. In this study, we constrain ourselves to static classification using segmentwise functionals of time-varying features, as the performance of static...
