Clustering analysis (CA) techniques consist in, given a set of objects, estimating dense regions of points separated by sparse regions, according to the dimensions that describe these objects. Independently from the data nature – structured or non-structured -, we look for homogenous clouds of points, that define clusters, from which we want to ext...

The clusters' analysis process comprises two broad activities: generation of a clusters set and extracting meaning from these clusters. The first one refers to the application of algorithms to estimate high density areas separated by lower density areas from the observed space. In the second one the analyst goes inside the clusters trying to figure...
