DSD_Target: 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

Value

• Returns a DSD_Target object which is a list of the defined params. The params are either passed in from the function or created internally. They include:
• description
  A brief description of the DSD object.
• k
  The number of clusters.
• d
  The number of dimensions.

Details

DSD_Target is a DSD generator for stream data. It has been implemented entirely in R, so there is no computational overhead with communicating to the Java Runtime Interface (JRI) or native C code. This DSD will produce a singular Gaussian cluster in the center with a ring around it.
