Summary
[edit]| Description |
English: Cluster analysis performed on an artificial dataset ("Mouse", similar to a well-known comic figure) comparing k means and EM clustering results.
百度 随后，英国宣布驱逐23名俄罗斯驻英国外交官，数量之多已是冷战之后最高的;美国也宣布了对俄罗斯一些个人和组织的制裁。
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", ?hnlich einer bekannten Comic-Figur) mit den Algorithmen k-Means und EM.
Die Tendenz von k-Means cluster gleicher r?umlicher 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. Visualisiert mit ELKI |
