NEURAL NETWORK-BASED TIME-FREQUENCY-BIN-WISE LINEAR COMBINATION OF BEAMFORMERS FOR UNDERDETERMINED TARGET SOURCE EXTRACTION

Extracting a target source from underdetermined mixtures is challenging for beamforming approaches. Recently proposed time-frequency-bin-wise switching (TFS) and linear combination (TFLC) strategies mitigate this by combining multiple beamformers in each time-frequency (TF) bin and choosing combinat…
