The K-nearest neighbor classification performance can often be significantly improved through metric learning. Popular algorithms are neighbourhood components analysis and large margin nearest neighbor. Supervised metric learning algorithms use the label information to learn a new metric or pseudo-metric.
Statistics became a separate department in 1955. [2] In 1951 Fix and Joseph Hodges, Jr. published their groundbreaking paper "Discriminatory Analysis. Nonparametric Discrimination: Consistency Properties," which defined the nearest neighbor rule, an important method that would go on to become a key piece of machine learning technologies, the k ...
Neighbourhood components analysis is a supervised learning method for classifying multivariate data into distinct classes according to a given distance metric over the data. Functionally, it serves the same purposes as the K-nearest neighbors algorithm and makes direct use of a related concept termed stochastic nearest neighbours .

KNN may refer to: k-nearest neighbors algorithm (k-NN), a method for classifying objects; Nearest neighbor graph (k-NNG), a graph connecting each point to its k nearest neighbors; Kabataan News Network, a Philippine television show made by teens; Khanna railway station, in Khanna, Punjab, India (by Indian Railways code)
Structured k-nearest neighbours (SkNN) [1] [2] [3] is a machine learning algorithm that generalizes k-nearest neighbors (k-NN). k-NN supports binary classification, multiclass classification, and regression, [4] whereas SkNN allows training of a classifier for general structured output.
The average silhouette of the data is another useful criterion for assessing the natural number of clusters. The silhouette of a data instance is a measure of how closely it is matched to data within its cluster and how loosely it is matched to data of the neighboring cluster, i.e., the cluster whose average distance from the datum is lowest.
