DSD_Target: Target Data Stream Generator

In mhahsler/stream: Infrastructure for Data Stream Mining

Target Data Stream Generator

Description

A data stream generator that generates a data stream in the shape of a target. It has a single Gaussian cluster in the center and a ring that surrounds it.

Usage

DSD_Target(
  center_sd = 0.05,
  center_weight = 0.5,
  ring_r = 0.2,
  ring_sd = 0.02,
  noise = 0
)

Arguments

center_sd	standard deviation of center
center_weight	proportion of points in center
ring_r	average ring radius
ring_sd	standard deviation of ring radius
noise	proportion of noise

Details

This DSD will produce a singular Gaussian cluster in the center with a ring around it.

Value

Returns a DSD_Target object.
