             abstract = "Data clustering is one of the main challenges when solving Data 
                         Science problems. Despite its progress over almost one century of 
                         research, clustering algorithms still fail in identifying groups 
                         naturally related to the semantics of the problem. Moreover, the 
                         technological advances add crucial challenges with a considerable 
                         data increase, which are not handled by most techniques. We 
                         address these issues by proposing a divide-and-conquer approach to 
                         a clustering technique, which is unique in finding one group per 
                         dome of the probability density function of the data --- the 
                         Optimum-Path Forest (OPF) clustering algorithm. Our approach can 
                         use all samples, or at least many samples, in the unsupervised 
                         learning process without affecting the grouping performance and, 
                         therefore, being less likely to lose relevant grouping 
                         information. We show that it can obtain satisfactory results when 
                         segmenting natural images into superpixels.",
