Density Based Data Clustering
... Clustering analysis is aimed at classifying objects into categories on the basis of their similarity, and, nowadays, it is a technique used in many different fields such as bioinformatics, image segmentation and market research [1]. The goal of data clustering is to find groups of similar objects in ...
