WebIn Section 2, we describe V-measure and how it is calculated in terms of homogeneity and complete-ness. We describe several popular external cluster evaluation measures and draw some comparisons to V-measure in Section 3. In Section 4, we discuss how some desirable properties for clustering are sat-ised by V-measure vs. other measures. In Sec- chin chin melbourne feed me menu

"In statistics, homogeneity and its opposite, heterogeneity, arise in describing the properties of a dataset, or several datasets. They relate to the validity of the often convenient assumption that the statistical properties of any one part of an overall dataset are the same as any other part. In meta-analysis, which combines the data from several studies, homogeneity measures the differences or similarities between the several studies (see also Study heterogeneity).
