Welcome to the
IFCS Cluster Benchmark Data Repository

The aim of this Repository is to stimulate better practice in benchmarking (performance comparison of methods) for cluster analysis by providing a variety of well documented high quality datasets and simulation routines for use in practical benchmarking.

The repository collects datasets with and without given "true" clusterings. A particular feature of the repository is that every dataset comes with a comprehensive documentation, including information on the specific nature of the clustering problem in this dataset and the characteristics that useful clusters should fulfill, with scientific justification.

Note: Up to May 15, 2017 a data set may be analyzed within the framework of a challenge! More information on this challenge is available here.
