Random kernel k-nearest neighbors regression [PDF]

open access: yesFrontiers in Big Data
The k-nearest neighbors (KNN) regression method, known for its nonparametric nature, is highly valued for its simplicity and its effectiveness in handling complex structured data, particularly in big data contexts.

Compressed kNN: K-Nearest Neighbors with Data Compression [PDF]

open access: yesEntropy, 2019
The kNN (k-nearest neighbors) classification algorithm is one of the most widely used non-parametric classification methods, however it is limited due to memory consumption related to the size of the dataset, which makes them impractical to apply to ...

Modernizing k‐nearest neighbors

open access: yesStat, 2021
The k‐nearest neighbors (k‐NN) method is one of the oldest statistical/machine learning techniques. It is included in virtually every major package, such as caret, parsnip, mlr3 and scikit‐learn. Yet those packages do not go beyond the basics. With today's high‐speed computation capability, k‐NN can be made much more powerful.

Recognizing steel elements with BRDF and k-nearest neighbors [PDF]

open access: yesMetrology and Measurement Systems, 2023
The paper deals with analysis of recognition of surface quality with reflective structures. Such surfaces are common in metallic materials cut using a saw or polished. There are no easy methods to identify such elements after machining.

Fast Approximate Complete-data k-nearest-neighbor Estimation

open access: yesAustrian Journal of Statistics, 2020
We introduce a fast method to estimate the complete-data set of k-nearest-neighbors.This is equivalent to finding an estimate of the k-nearest-neighbor graph of the data. The method relies on random normal projections.

MGR: Efficiently Processing Maximal Group Reverse k Nearest Neighbors Queries

open access: yesIEEE Access, 2022
Given a set of facilities and a set of clients, a reverse $k$ nearest neighbors ( $\text{R}k$ NN) query returns every client for which the query facility is one of the $k$ -closest facilities.
