MGNR: A Multi-Granularity Neighbor Relationship and Its Application in KNN Classification and Clustering Methods

IEEE Transactions on Pattern Analysis and Machine Intelligence
In the real world, data distributions often exhibit multiple granularities. However, the majority of existing neighbor-based machine-learning methods rely on manually setting a single-granularity for neighbor relationships. These methods typically handle

A Variable Granularity Search-Based Multiobjective Feature Selection Algorithm for High-Dimensional Data Classification

IEEE Transactions on Evolutionary Computation, 2023
Evolutionary algorithms (EAs) have shown their competitiveness in solving the problem of feature selection (FS). However, in most of the existing EA-based FS methods, one bit in the individual only represents one feature, which means with the number of ...
