Challenges of community detection cite:curtis2017estimation

  1. Clustering is computationally intensive and is not feasible to perform regularly.
  2. Clustering algorithms typically assign nodes to only the single most suitable cluster.
    • To solve this, Ancestry built a classification algorithm for each community.
  3. While clustering is consistent across an entire database, individual assignments may change across repetitions.
