Agglomerative Ants for Data Clustering
Clustering is a data mining technique for the analysis of data in various areas such as pattern recognition, image processing, information science, bioinformatics etc. Hierarchical clustering techniques form the clusters based on top-down and bottom-up approaches. Hierarchical agglomerative clustering is a bottom-up clustering method. Ant based clustering methods form clusters by picking and dr...
متن کاملNegentropy Based Agglomerative Clustering for Microarray Data
Scientists have been successful in cataloguing genes through genome sequencing projects, and they can now generate vast quantities of gene expression data using microarrays. However, due to the sheer size of the data sets involved, and to complexity of the problems to be tackled, the biological comunity has so far had less success in understanding how genes and proteins are connected and how th...
متن کاملAgglomerative clustering on vertically partitioned data
Mining distributed databases is emerging as a fundamental computational problem. A common approach for mining distributed databases is to move all of the data from each database to a central site and a single model is built. Privacy concerns in many application domains prevents sharing of data, which limits data mining technology to identify patterns and trends from large amount of data. Tradit...
متن کاملAn On-line Agglomerative Clustering Method for Non-Stationary Data
An on-line agglomerative clustering algorithm for nonstationary data is described. Three issues are addressed. The first regards the temporal aspects of the data. The clustering of stationary data by the proposed algorithm is comparable to the other popular algorithms tested (batch and on-line). The second issue addressed is the number of clusters required to represent the data. The algorithm p...
متن کاملAgglomerative Info-Clustering
An agglomerative clustering of random variables is proposed, where clusters of random variables sharing the maximum amount of multivariate mutual information are merged successively to form larger clusters. Compared to the previous info-clustering algorithms, the agglomerative approach allows the computation to stop earlier when clusters of desired size and accuracy are obtained. An efficient a...
