Diversity control for improving the analysis of consensus clustering
(Elsevier Science Inc, 2016-09)
Consensus clustering has emerged as a powerful technique for obtaining better clustering results, where a set of data partitions (ensemble) are generated, which are then combined to obtain a consolidated solution (consensus ...
Interactive textual feature selection for consensus clustering
(ElsevierAmsterdam, 2015-01)
Consensus clustering and interactive feature selection are very useful methods to extract and manage knowledge from texts. While consensus clustering allows the aggregation of different clustering solutions into a single ...
A Method to Improve the Analysis of Cluster Ensembles
(Sociedad Iberoamericana de Inteligencia Artificial, 2014-03)
Clustering is fundamental to understand the structure of data. In the past decade the cluster ensembleproblem has been introduced, which combines a set of partitions (an ensemble) of the data to obtain a singleconsensus ...
Community detection by consensus genetic-based algorithm for directed networks
(Wiley-Blackwell, 2016)
Finding communities in networks is a commonly used form of network analysis. There is a myriad of community detection algorithms in the literature to perform this task. In spite of that, the number of community detection ...
Clustering ensembles and space discretization - A new regard toward diversity and consensus
(Elsevier Science BvAmsterdamHolanda, 2010)
An Experimental Study on Microarray Expression Data from Plants under Salt Stress by using Clustering Methods
Current Genome-wide advancements in Gene chips technology provide in the “Omics (genomics, proteomics and transcriptomics) research”, an opportunity to analyze the expression levels of thousand of genes across multiple ...
Comparing hard and overlapping clusterings
(MicrotomeBrookline, 2015-12)
Similarity measures for comparing clusterings is an important component, e.g., of evaluating clustering algorithms, for consensus clustering, and for clustering stability assessment. These measures have been studied for ...
