On k-Nearest Neighbor Voronoi Diagrams in the Plane
IEEE Transactions on Computers, 1982The notion of Voronoi diagram for a set of \(N\) points in the Euclidean plane is generalized to the Voronoi diagram of order \(k\) and an iterative algorithm to construct the generalized diagram in \(O(k^2N \log N)\) time using \(O(k^2(N-k))\) space is presented.

Hybrid k -Nearest Neighbor Classifier.
IEEE transactions on cybernetics, 2016Conventional k -nearest neighbor (KNN) classification approaches have several limitations when dealing with some problems caused by the special datasets, such as the sparse problem, the imbalance problem, and the noise problem. In this paper, we first perform a brief survey on the recent progress of the KNN classification approaches.

Classification Bias of the k-Nearest Neighbor Algorithm
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1984The k-nearest neighbor classifier has been used extensively in pattern analysis applications. This classifier can, however, have substantial bias when there is little class separation and the sample sizes are unequal. This classification bias is examined for the two-class situation and formulas presented that allows selection of values of k that yields
