... from polyphonic sounds. As de- scribed in the introduction, this modeling makes weighting features to minimize the in uence of the overlapping prob- lem equivalent to applying LDA to training ... a mixture of sounds. 2.3. Feature weighting based on robustness to overlapping of sounds As described in the previous section, the in uence of the overlapping of sou...
