Abstract:This paper focuses on estimating clustering validity by using logistic regression. For many applications it might be important to estimate the quality of the clustering, e.g. in case of speech segments' clustering, make a decision whether to use the clustered data for speaker verification. In the case of short segments speakers clustering, the common criteria for cluster validity are average cluster purity (ACP), average speaker purity (ASP) and K -the geometric mean between the two measures. As in practice, t… Show more
