Denclue: Technical Essence

  • Uses grid cells but only keeps information about grid cells that do actually contain data points and manages these cells in a tree-based access structure
  • Influence function: describes the impact of a data point within its neighborhood
  • Overall density of the data space can be calculated as the sum of the influence function of all data points
  • Clusters can be determined mathematically by identifying density attractors
  • Density attractors are local maximal of the overall density function
  • Center defined clusters: assign to each density attractor the points density attracted to it
  • Arbitrary shaped cluster: merge density attractors that are connected through paths of high density (> threshold)
