About: Neighbourhood components analysis

An Entity of Type: software, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

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.

Property Value
dbo:abstract
  • 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. (en)
  • 邻里成分分析（Neighborhood components analysis，NCA）是一种监督式学习的方法，根据一种给定的距离度量算法对样本数据进行度量，然后对多元变量数据进行分类。在功能上其和k近邻算法的目的相同，直接利用随即近邻的概念确定与测试样本临近的有标签的训练样本。 (zh)
