Point Classifications in DBSCAN Clustering

The DBSCAN algorithm classifies data points into three categories based on two parameters: neighborhood radius (ϵ\epsilon) and minimum points (min_samplesmin\_samples).

  • Core Point: A point with at least min_samplesmin\_samples points within its ϵ\epsilon-neighborhood.
  • Border Point: A point within ϵ\epsilon distance of a core point, but with fewer than min_samplesmin\_samples neighbors itself.
  • Noise: A point that is neither a core point nor a border point.
