A non-parametric method to estimate the number of clusters

Fujita, André; Takahashi, Daniel Y.; Patriota, Alexandre G. - In: Computational Statistics & Data Analysis 73 (2014) C, pp. 27-39

An important and yet unsolved problem in unsupervised data clustering is how to determine the number of clusters. The proposed slope statistic is a non-parametric and data driven approach for estimating the number of clusters in a dataset. This technique uses the output of any clustering...
