Clustering Datasets

A few useful clustering dataset links:
UCI -- classification datasets that can be used for clustering by ignoring the class label. The class label is useful for evaluating the accuracy of the clusterer in recreating the known classification (though care should be taken -- producing clusters that do not directly match the known classes doesn't mean the clusters are bad...): https://archive.ics.uci.edu/ml/datasets.html

Handl et al. -- hyper-spherical synthetic datasets with high dimensionality and number of clusters (up to 100 and 40 respectively): http://personalpages.manchester.ac.uk/mbs/julia.handl/generators.html

A collection of other datasets, including some interesting non-hyper-spherical (NHS) ones: https://cs.joensuu.fi/sipu/datasets/
