Abstract: K-Nearest Neighbor (KNN) is a very simple and powerful classification algorithm. In this paper, we propose a new KNN-based classifier, called local density-based nearest neighbors (LDBNN). It considers that a target instance should be classified in a class whose the k nearest neighbors constitute a dense region, where the neighbors are near to each other and also near to the target instance. The performance of the proposed algorithm was compared with the performance of 5 important KNN-based classifiers. The performance was evaluated in terms of accuracy in 16 well-known datasets. The experimental results show that the proposed algorithm achieves the highest accuracy in most of the datasets.
