Definition of Strategies for Crime Prevention and Combat Using Fuzzy Clustering and Formal Concept Analysis
(World Scientific Publ Co Pte Ltd, 2018)
Public security has always been an important research topic. In this sense, machine learning algorithms have been used to extract knowledge from criminal databases, which usually maintain records in order to generate ...
Named entities as privileged information for hierarchical text clustering
(Association for Computing Machinery - ACMInstituto Superior de Engenharia do Porto - ISEPPorto, 2014-07)
Text clustering is a text mining task which is often used to aid the organization, knowledge extraction, and exploratory search of text collections. Nowadays, the automatic text clustering becomes essential as the volume ...
OGLE II Observations of Star Clusters in the Magellanic Clouds
(2002)
In the course of the OGLE II experiment we have collected up to now about one billion BVI observations of ten million stars in the Magellanic Clouds. Based on that data about 1000 star clusters were detected with an automatic ...
Towards improving cluster-based feature selection with a simplified silhouette filter
(ELSEVIER SCIENCE INC, 2011)
This paper proposes a filter-based algorithm for feature selection. The filter is based on the partitioning of the set of features into clusters. The number of clusters, and consequently the cardinality of the subset of ...
Partitions selection strategy for set of clustering solutions
(ELSEVIER SCIENCE BV, 2010)
Clustering is a difficult task: there is no single cluster definition and the data can have more than one underlying structure. Pareto-based multi-objective genetic algorithms (e.g., MOCK Multi-Objective Clustering with ...
Generating a magellanic star cluster catalog with ASteCA
(Asociación Argentina de Astronomía, 2016-11)
An increasing number of software tools have been employed in the recent years for the automated or semi-automated processing of astronomical data. The main advantages of using these tools over a standard by-eye analysis ...
