A Batch of Integer Data Sets for Clustering Algorithms

# A Batch of Integer Data Sets for Clustering Algorithms

# Description

This is a simple batch of data sets of points containing only integer attributes.

The data sets were generated with a randomly correlated data set generator (DOI:10.13140/RG.2.2.34866.43200).

This batch includes a total of 12 data sets, for all possible combinations of the following parameter ranges:

- N (number of points) = {32k, 64k}

- K (number of clusters) = {8, 16}

- D (number of attributes) = {2, 8, 16}

The data sets are named accordingly, e.g., *N32_K8_D2.txt*. Also included are secondary files with one instance of possible initial centroid values per data set, computed by a run of the *k-means++* algorithm. These values were employed in the research paper referred to at the end of this README.

Data set files are formated such that each row is a complete datum, where attributes are separated by **whitespace**.
