    HDBSCAN is a popular hierarchical density based clustering algorithm with an efficient python implementation. In this talk we show how it works, why it works and why it should be among the first algorithms you use when exploring a new data set. Further we will show how we took an inherently O(n^2) algorithm and turned it into the O(nlogn) algorithm that is available in scikit-learn-contrib.

    15:30 there might be a misprint in the formula: d(X_i, X_j), not d(X_j, X_j)

    Thank you for the super interesting talk! I was wondering if you have worked with the new HDBSCAN integrated in sklearn 1.3.0? Is it possible to draw the cluster tree with this implementation?

    Any idea why the GPU version of this method can't take a pre-computed distance matrix?

  • @TrixieFromSanFran

    The coloring of the tree at 14:00 is needlessly confusing. See figure 3a in their paper McInnes & Healy 2017 to clarify things

    clustering is highly driven by the formatting of how the data relates to itself
    and is near impossible to accomplish using a single method of approach.

    • @RoulDukeGonzo
      @RoulDukeGonzo Před 18 dny

      Agree, but in practical terms, where do you start?

    • @0MVR_0

      @@RoulDukeGonzo An intimate descriptive knowledge of the data is recommended.
