Data Generator

Creates random data containing some clusters for Parallel Universes. The data contains a certain fraction of noise patterns and data that is generated to clusters (all clusters have the same size). The data is normalized in [0, 1].

Options

Cluster Count: The number of clusters for each universe (comma separated).
Universe Sizes: The number of attributes for each universe (comma separated).
Pattern Count: Number of patterns (overall).
Standard Deviation: Std. dev. for each cluster.
Noise Fraction: Fraction of the overall data to be noise, i.e. randomly drawn data. This value must be in [0, 1].
Random Seed: Seed for "deterministic" data generation.
