Area of Science:

  • Data Science
  • Machine Learning
  • Computational Statistics

Background:

  • Clustering algorithms often suffer from instability due to initialization sensitivity.
  • Achieving a robust and consistent data partition remains a challenge in unsupervised learning.
  • Determining the optimal number of clusters is crucial for meaningful data interpretation.

Purpose of the Study:

  • To present a multi-clustering fusion method for enhanced data partitioning.
  • To overcome the inherent instabilities and initialization dependencies of single clustering runs.
  • To develop a procedure for reliably determining the optimal number of clusters.

Main Methods:

  • Combining results from multiple independent runs of a clustering algorithm.
  • Generating a common, stable data partition resistant to initialization variations.
