A New Gravitational Clustering Algorithm

... Many clustering techniques rely on the assumption that a data set follows a certain distribution and is free of noise Given noise, several techniques (k-means, fuzzy k-means) based on a least squares estimate are spoiled Most clustering algorithms require the number of clusters to be specified The a ...
