WebBk is the calculation of Fowlkes-Mallows index for a series of k cuts for two dendrograms. A Bk plot is simply a scatter plot of Bk versus k. This plot helps in identifiying the similarity between two dendrograms in different levels of k (number of clusters). WebThe G-measure (or Fowlkes–Mallows index) is the geometric mean of the precision and recall. Below is a plot of the different means.
