Synthetic data
Description
Synthetic dataset with 2 non-spherical clusters.
Usage
data(synt.data)
Format
A matrix with 302 rows and 2 columns.
Details
Although two clusters are clearly visible, fuzzy k-means fails to discover them. The Gustafson and Kessel-like fuzzy k-means should be used for finding the known-in-advance clusters.
