PDF-On the performance of bisecting Kmeans and PDDP Sergi

Savaresi and Daniel L Boley 1 Introduction and problem statement The problem this paper focuses on is the unsupervised clustering of a dataset The data set is given by the matrix where each column of is a single datapoint This is one of the more. Although it o64256ers no accuracy guarantees its simplicity and speed are very appealing in practice By augmenting kmeans with a very simple ran domized seeding technique we obtain an algorithm that is 920log competitive with the optimal clustering Hermans Z Sergi GarciaManyes Kirstin A Walther Julio M Fernandez Columbia University New York NY 10027 USA 12 October 2006 Abstract Using the recently developed single molecule forceclamp technique we quantita tively measure the kinetics of conforma Liver Biopsy in Modern Medicine 296 the cranial portion of the primitive foregut and grow towards a loosely arranged mesoderm in the direction of the plexus vitellinus of the embryo.
