A pre-averaged pseudo nearest neighbor classifier [PDF]

open access: yesPeerJ Computer Science
The k-nearest neighbor algorithm is a powerful classification method. However, its classification performance will be affected in small-size samples with existing outliers.

Random k conditional nearest neighbor for high-dimensional data [PDF]

open access: yesPeerJ Computer Science
The k nearest neighbor (kNN) approach is a simple and effective algorithm for classification and a number of variants have been proposed based on the kNN algorithm. One of the limitations of kNN is that the method may be less effective when data contains

Approximate Nearest Neighbor Search Based on Neighbor Graphs with Parameter Adaptation [PDF]

open access: yesJisuanji gongcheng, 2022
Approximate Nearest Neighbor Search(ANNS) algorithms based on neighbor graphs typically organize vectors in a database into a neighbor graph structure and obtain the Approximate Nearest Neighbor(ANN) of the query vector by leveraging user-specified ...

A multi-voter multi-commission nearest neighbor classifier

open access: yesJournal of King Saud University: Computer and Information Sciences, 2022
Many improved versions of k-nearest neighbor (KNN) have been proposed by minimizing total distances of multi k nearest neighbors (multi-voter) in each class instead of the majority voting, such as a local mean-based pseudo nearest neighbor (LMPNN) that ...

Quality-related fault diagnosis based on -nearest neighbor rule for non-linear industrial processes

open access: yesInternational Journal of Distributed Sensor Networks, 2021
The fault diagnosis approaches based on k -nearest neighbor rule have been widely researched for industrial processes and achieve excellent performance. However, for quality-related fault diagnosis, the approaches using k -nearest neighbor rule have been

Mixture of the nearest- and next-nearest-neighbor d + id-wave pairings on the honeycomb lattice

open access: yesNew Journal of Physics, 2022
Symmetry of superconducting pairing is one of the cardinal issues in superconductivity. In general, the nearest-neighbor and next-nearest-neighbor pairings cannot spontaneously mix with each other constrained by the distinct symmetry classification, for ...

Nearest neighbor estimates of Kaniadakis entropy

open access: yesAnalele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2022
The aim of this paper is to develop new nonparametric estimators of entropy based on the kth nearest neighbor distances that are considered between n sample points, k ≤ (n − 1) being a positive integer, fixed.
