This study introduces NNC-Trees, a novel decision tree approach using nearest neighbor classifiers. This method enhances classification efficiency and structure for complex data analysis.

Area of Science:

  • Machine Learning
  • Artificial Intelligence
  • Data Mining

Background:

  • Conventional axis-parallel decision trees (APDTs) have limitations in decision boundary complexity.
  • Single-layer nearest neighbor classifiers (NNCs) lack hierarchical structure for complex data.
  • Hierarchical classification structures are valuable in numerous applications.

Purpose of the Study:

  • To propose an algorithm for inducing NNC-Trees, a novel decision tree structure.
  • To enhance classification efficiency and model complexity compared to APDTs.
  • To enable hierarchical data classification using NNCs.

Main Methods:

  • Development of an algorithm for inducing NNC-Trees based on the R4-rule.
  • Definition of heuristic teacher signals (group labels) for non-terminal nodes.
