Summary
Description KMeans-Gaussian-data.svg |
Deutsch:
k-Means-Algorithmus
-
Clusteranalyse
auf einem Datensatz mit Gauss-verteilten Clustern. k-Means erwartet gleich große Cluster, die Partitionierung mittels Voronoi-Zellen kann die wahre Clusterstruktur nicht darstellen. Selbst die von k-Means gefundenen Clusterzentren sind nur annähernd korrekt.

English:
Cluster analysis
with
k-Means
on a gaussian-distribution-based data set. k-Means is unable to handle the different cluster sizes (spatial sizes) and is barely able to approximate the cluster centers. See
File:EM-Gaussian-data.svg
for the results when using the
EM-algorithm
, which can deal with clusters of different spatial extend.
The visualization was generated using
