# Data Clustering Software ## CLUTO - Software for Clustering High-Dimensional Datasets CLUTO is a software package for clustering low- and high-dimensional datasets and for analyzing the characteristics of the various clusters. CLUTO is well-suited for clustering data sets arising in many diverse application areas including information retrieval, customer purchasing transactions, web, GIS, science, and biology. CLUTO's distribution consists of both stand-alone programs and a library via which an application program can access directly the various clustering and analysis algorithms implemented in CLUTO. **Features** - Multiple classes of clustering algorithms: - partitional, agglomerative, & graph-partitioning based. - Multiple similarity/distance functions: - Euclidean distance, cosine, correlation coefficient, extended Jaccard, user-defined. - Numerous novel clustering criterion functions and agglomerative merging schemes. - Traditional agglomerative merging schemes: - single-link, complete-link, UPGMA - Extensive cluster visualization capabilities and output options: - postscript, SVG, gif, xfig, etc. - Multiple methods for effectively summarizing the clusters: - most descriptive and discriminating dimensions, cliques, and frequent itemsets. - Can scale to very large datasets containing hundreds of thousands of objects and tens of thousands of dimensions. > The CLUTO data clustering package is currently distributed as a single file that > contains binary distributions for Linux, OSX, and MS Windows platforms. > > The first step in getting and using CLUTO is to download the binary distribution > file.
