genie: A New, Fast, and Outlier Resistant Hierarchical Clustering Algorithm by Marek Gagolewski, Maciej Bartoszuk, and Anna Cena
A new hierarchical clustering linkage criterion: the Genie algorithm links two clusters in such a way that a chosen economic inequity measure (e.g., the Gini index) of the cluster sizes does not increase drastically above a given threshold. Benchmarks indicate a high practical usefulness of the introduced method: it most often outperforms the Ward or average linkage in terms of the clustering quality while retaining the single linkage speed.
