DSD_Benchmark: Data Stream Generator for Dynamic Data Stream Benchmarks

Description

A data stream generator that generates several dynamic streams indented to be benchmarks to compare data stream clustering algorithms. The benchmarks can be used to test if a clustering algorithm can follow moving clusters, and merging and separating clusters.

Usage

DSD_Benchmark(i = 1)

Value

Returns a DSD object.

Arguments

i

integer; the number of the benchmark.

Author

Michael Hahsler

Details

Currently available benchmarks are:

• 1: two tight clusters moving across the data space with noise and intersect in the middle.

• 2: two clusters are located in two corners of the data space. A third cluster moves between the two clusters forth and back.

The benchmarks are created using DSD_MG.

get_points(stream, n = 5)

if (FALSE) {
stream <- DSD_Benchmark(i = 1)
animate_data(stream, n = 10000, horizon = 100, xlim = c(0, 1), ylim = c(0, 1))

stream <- DSD_Benchmark(i = 2)
animate_data(stream, n = 10000, horizon = 100, xlim = c(0, 1), ylim = c(0, 1))
