DSD_Cubes: Static Cubes Data Stream Generator

In stream: Infrastructure for Data Stream Mining

Static Cubes Data Stream Generator

Description

A data stream generator that produces a data stream with static (hyper) cubes filled uniformly with data points.

Usage

DSD_Cubes(k = 2, d = 2, center, size, p, noise = 0, noise_range)

Arguments

k	Determines the number of clusters.
d	Determines the number of dimensions.
center	A matrix of means for each dimension of each cluster.
size	A k times d matrix with the cube dimensions.
p	A vector of probabilities that determines the likelihood of generated a data point from a particular cluster.
noise	Noise probability between 0 and 1. Noise is uniformly distributed within noise range (see below).
noise_range	A matrix with d rows and 2 columns. The first column contains the minimum values and the second column contains the maximum values for noise.

Value

Returns a DSD_Cubes object (subclass of DSD_R, DSD).
