Resumen o descripción

In clustering, providing an explanation of the results is an important task.

Pattern-based clustering algorithms provide, in addition to the list of objects

belonging to each cluster, an explanation of the results in terms of a set of

patterns that describe the objects grouped in each cluster. It makes these

algorithms very attractive from the practical point of view; however, patternbased

clustering algorithms commonly have a high computational cost in the

clustering stage. Moreover, the most recent algorithms proposed within this

approach, extract patterns from numerical datasets by applying an a priori

discretization process, which may cause information loss. In this thesis, we

propose new algorithms for extracting only a subset of patterns useful for

clustering, from a collection of diverse unsupervised decision trees induced

from a dataset. Additionally, we propose a new clustering algorithm based

on these patterns.
