This study presents an improved Voronoi diagram clustering method for classifying random data, especially effective for overlapping distributions. The technique enhances data clustering accuracy using directional vectors and a correction process.

Area of Science:

  • Computational statistics
  • Data mining
  • Pattern recognition

Background:

  • Traditional clustering methods struggle with overlapping data distributions.
  • Voronoi diagrams offer a spatial partitioning approach but have limitations with complex data.
  • Enhancing Voronoi diagrams is crucial for robust data classification.

Purpose of the Study:

  • Introduce a novel clustering technique for random data classification.
  • Improve handling of spatially overlapping data distributions.
  • Provide a mathematical framework for enhanced Voronoi diagram analysis.

Main Methods:

  • Developed an enhanced Voronoi diagram incorporating a correction process.
  • Introduced directional vectors for Gaussian and elliptical data distributions.
