“…Another extension of Classify is Scale [9,13,14,19,45,48,49,53,62,68,83,94,132,144,199,225,226,238,261,275,280,303,320,336,337,[339][340][341]390] [425] use Classify in comparing rhythmic features (statistics of an autocorrelation of wavelet decomposition) and timbral features (spectral centroid, rolloff, etc.). On the other hand, Yoon et al [459] explore two different feature selection approaches using Classify, but do not discuss or list the selected features. Akin to Features is a fifth design, Rules, which appears in at least sixteen works [3,5,13,14,26,42,43,70,94,98,139,303,308,340,341,434].…”
