Interface AssignCluster<D>

All Known Implementing Classes:
AssignGmm_F64, AssignKMeans
public interface AssignCluster<D>
Used to assign a point to set of clusters. Clusters are given labels from 0 to N-1, where N is the number of clusters.

  • Method Summary

    Modifier and Type
    Method
    Description
    int
    assign(D point)
    Assigns the point to cluster which is the best fit.
    void
    assign(D point, double[] fit)
    Performs a soft assignment of a point to all the clusters.
    int
    getNumberOfClusters()
    Total number of clusters.

  • Method Details

    • assign

      int assign(D point)
      Assigns the point to cluster which is the best fit.
      Parameters:
      point - Point which is to be assigned
      Returns:
      Index of the cluster from 0 to N-1

    • assign

      void assign(D point, double[] fit)
      Performs a soft assignment of a point to all the clusters. Clusters with a better fit will have a larger value in 'fit'. The sum of fit is equal to 1, unless everything is zero. Then it is zero.
      Parameters:
      point - Point which is to be assigned
      fit - Storage for relative fit quality of each cluster. Length must be at least the number of clusters.

    • getNumberOfClusters

      int getNumberOfClusters()
      Total number of clusters.
      Returns:
      The total number of clusters.
