How many clusters ?
The title poses a deceptively simple question that must be addressed by any statistical model or computational algorithm for the clustering of points. Two distinct interpretations are possible, one connected with the number of clusters in the sample and one with the number in the population. Under suitable conditions, these questions may have essentially the same answer, but it is logically pos...
متن کاملHow many clusters in the insular cortex?
In their recent paper, Chang et al. (2012) explained some inconsistencies in the results for the number of insular cortex clusters. They reported three insular clusters, one anterior dorsal, one posterior dorsal, and one middle-anterior ventral. In a previous paper (Cauda et al. 2011) on the same subject, we parcellated the insula into two clusters, one anterior ventral and one posterior dorsal...
متن کاملHow Many Clusters? An Information-Theoretic Perspective
Clustering provides a common means of identifying structure in complex data, and there is renewed interest in clustering as a tool for the analysis of large data sets in many fields. A natural question is how many clusters are appropriate for the description of a given system. Traditional approaches to this problem are based on either a framework in which clusters of a particular shape are assu...
متن کاملHow many young star clusters exist in the Galactic center ?
We study the evolution and observability of young compact star clusters within ∼ 200 pc of the Galactic center. Calculations are performed using direct N-body integration on the GRAPE-4, including the effects of both stellar and binary evolution and the external influence of the Galaxy. The results of these detailed calculations are used to calibrate a simplified model applicable over a wider r...
متن کاملHow many patients? How many doctors?
O ne of the fastest growing fields in medicine is the care of adults with congenital heart disease (adult CHD or ACHD). This is mainly a consequence of much longer survival due to advances in pediatric cardiology, interven-tional catheterization, cardiac surgery, and intensive care. Fifty years ago we could diagnose most forms of moderate and severe CHD, but some anomalies were untreatable and ...
