The suite includes 48 synthetic data files created by Jose Dula. Detailed information about the data generation process can be found in Dula (2008).

The data sets vary in four cardinality levels (n = 25K, 50K, 75K, 100K), four dimensions (m = 5, 10, 15, 20) and three density levels (d = 1%, 10%, 25%).
