Summary

Description
English: Cluster analysis performed on an artificial dataset ("Mouse", similar to a well-known comic figure) comparing k means and EM clustering results.

The tendency of k-Means to produce clusters of the same extends produces bad results, while the Gaussian nature of the data is well recognized by EM.

The visualization was generated using ELKI.
Deutsch: Clusteranalyse auf einem künstlichen Datensatz ("Maus", ähnlich einer bekannten Comic-Figur) mit den Algorithmen k-Means und EM.

Die Tendenz von k-Means cluster gleicher räumlicher Ausdehnung zu produzieren führt zu einem schlechten Ergebnis. Der aus Normalverteilungen bestehende Datensatz ist dagegen ideal für EM, das die Daten mit Normalverteilungen zu modellieren versucht.

This file is translated using SVG <switch> elements. All translations are stored in the same file! Learn more.

For most Wikipedia projects, you can embed the file normally (without a lang parameter). The Wikipedia will use its language if the SVG file supports that language. For example, the German Wikipedia will use German if the SVG file has German. To embed this file in a particular language use the lang parameter with the appropriate language code, e.g. [[File:ClusterAnalysis Mouse.svg|lang=en]] for the English version. Do not specify a lang parameter if it is not needed. The parameter may prevent the use of a subsequent translation.

To translate the text into your language, you can use the SVG Translate tool. Alternatively, you can download the file to your computer, add your translations using whatever software you're familiar with, and re-upload it with the same name. You will find help in Graphics Lab if you're not sure how to do this.
