Density-Based Clustering in Cloud-Oriented Collaborative Multi-Agent Systems
The development of new reliable data processing and mining methods based on the synergy between cloud computing and the multi-agent paradigm is of great importance for contemporary and future software systems. Cloud computing provides huge volumes of data and computational resources, whereas the agents make the system components more autonomous, cooperative, and intelligent. This creates the ne...
متن کاملHierarchical Density-Based Clustering for Multi-Represented Objects
In recent years, the complexity of data objects in data mining applications has increased as well as their plain numbers. As a result, there exist various feature transformations and thus multiple object representations. For example, an image can be described by a text annotation, a color histogram and some texture features. To cluster thesemulti-represented objects, dedicated datamining algori...
متن کاملImprovement of density-based clustering algorithm using modifying the density definitions and input parameter
Clustering is one of the main tasks in data mining, which means grouping similar samples. In general, there is a wide variety of clustering algorithms. One of these categories is density-based clustering. Various algorithms have been proposed for this method; one of the most widely used algorithms called DBSCAN. DBSCAN can identify clusters of different shapes in the dataset and automatically i...
متن کاملDensity Based Text Clustering
As the discovery of information from text corpora becomes more and more important there is a necessity to develop clustering algorithms designed for such a task. One of the most, successful approach to clustering is the density based methods. However due to the very high dimensionality of the data, these algorithms are not directly applicable. In this paper we demonstrate the need to suitably e...
متن کاملDensity-Based Clustering Validation
One of the most challenging aspects of clustering is validation, which is the objective and quantitative assessment of clustering results. A number of different relative validity criteria have been proposed for the validation of globular, clusters. Not all data, however, are composed of globular clusters. Density-based clustering algorithms seek partitions with high density areas of points (clu...
