k-NN intuitionistic fuzzy classifier
Eulalia J Szmidt, Janusz Kacprzyk, Paweł Bujnowski · Notes on Intuitionistic Fuzzy Sets · 2025
The k-NN (k-Nearest Neighbor) classifier is one of the commonly used classifiers. We present a modification of this classifier based on Atanassov's intuitionistic fuzzy sets (IFSs, for short). We show, using benchmark data from UCI Machine Learning Repository, that the classifier we propose achieves very good results.
