WebEuclidean Distance Examples Example 1: Determine the Euclidean distance between two points (a, b) and (-a, -b). Solution: Let the point P be (a, b) and Q be (-a, -b) i.e. P (a, b) = (x 1, y 1) and Q (-a, -b) = (x 2, y 2) We know that the Euclidean distance formula is, Euclidean distance, d = √ [ (x 2 – x 1) 2 + (y 2 – y 1) 2 ] WebThe Mahalanobis distance is a measure of the distance between a point P and a distribution D, introduced by P. C. Mahalanobis in 1936. Mahalanobis's definition was prompted by the problem of identifying the similarities of skulls based on measurements in 1927. It is a multi-dimensional generalization of the idea of measuring how many …
