butterfly: butterfly dataset

Description

Synthetic dataset.

Usage

data(butterfly)

Format

A matrix with 15 rows and 2 columns.

Details

The butterfly dataset motivates the need for the fuzzy approach to clustering. Two clusters are clearly visible, but unit n.8 is between the two clusters, and hence its assignment is complex for standard clustering methods.
