Cluster analysis relies on effective benchmarks for evaluating and comparing different algorithms. Simulation studies on synthetic data are popular because important features of the data sets, such as the overlap between clusters, or the variation in cluster shapes, can be effectively varied. Unfortunately, creating evaluation scenarios is often laborious, as Also, small datasets are artificially generated via the Multidimensional Dataset Generator for Clustering (MDCGen) [27] to analyse the parameters of the

To test if npGLC-Vis techniques are useful for detecting clusters and outliers, we create a synthetic dataset using MDCGEN [7] (Multidimensional Dataset for Clustering Generator) that is a tool for testing clustering algorithmic in a wide range of use cases. MDCStream is a MATLAB tool for generating temporal-dependent numerical datasets in order to stress-test stream data classification, clustering, and outlier detection algorithms. MDCStream is built on MDCGen, therefore showing a high flexibility for creating a

Abstract We present a tool for generating multidimensional synthetic datasets for testing, evaluating, and benchmarking unsupervised classification algorithms. Our proposal fills a gap observed in previous approaches with regard to underlying distributions for the creation of multidimensional clusters. As a novelty, normal and non-normal distributions can be combined First, skeletons of the clusters are constructed following a random walk. In the second step, these skeletons are enriched with data samples. DENSIRED enables the systematic generation of data for a robust and reliable analysis of methods aimed toward examining data containing density-connected clusters.

The synthetic dataset generator embedded in our solution is MDCGen (Multidimensional Dataset Generator for Clustering), developed by [4]. MDCGen is an open source tool implemented in MATLAB and Python. Additionally, MDCGen implements classic functionalities, e.g., customization of cluster-separation, overlap control, addition of outliers and noisy features, correlated variables, rotations, and dataset quality evaluations, among others.
