Machine learning algorithm principle, implementation and practice-Distance measurement  Statement: most of the content in this article is reproduced in July's article on CSDN: from the K nearest neighbor algorithm and distance measurement to the KD

Pearson correlation coefficientExamine the degree of correlation between two things (what we call variables in the data), simply by measuring whether two data sets are on a line. The formula is: or ORn indicates the number of variables to be

1.1, what is the K nearest neighbor algorithmWhat is the K nearest neighbor algorithm, namely K-nearest Neighbor algorithm, short of the KNN algorithm, single from the name to guess, can be simple and rough think is: K nearest neighbour, when K=1,

Recently I have been studying the r language, which involves some functions involved in association analysis. Three of them are associated with each other: VaR: Calculate the variance of a Variable Cov: Calculates the covariance of two

Similarity measurement between different samples is often needed for classification. The common method is to calculate the distance between samples ). The method used to calculate distance is very particular, and even related to the correctness of
