"In statistics, the k-nearest neighbors algorithm (k-NN) is a non-parametric supervised learning method first developed by Evelyn Fix and Joseph Hodges in 1951, and later expanded by Thomas Cover. It is used for classification and regression. In both cases, the input consists of the k closest training examples … Meer weergeven The training examples are vectors in a multidimensional feature space, each with a class label. The training phase of the algorithm consists only of storing the feature vectors and class labels of the training … Meer weergeven The k-nearest neighbour classifier can be viewed as assigning the k nearest neighbours a weight $${\displaystyle 1/k}$$ and all others 0 weight. This can be generalised … Meer weergeven The K-nearest neighbor classification performance can often be significantly improved through (supervised) metric learning. Popular algorithms are neighbourhood components analysis and large margin nearest neighbor. Supervised metric … Meer weergeven The best choice of k depends upon the data; generally, larger values of k reduces effect of the noise on the classification, but make boundaries between classes less distinct. … Meer weergeven The most intuitive nearest neighbour type classifier is the one nearest neighbour classifier that assigns a point x to the class of its closest neighbour in the feature … Meer weergeven k-NN is a special case of a variable-bandwidth, kernel density "balloon" estimator with a uniform kernel.
