For efficiency reasons, the euclidean distance between a pair of row vector x and y is computed as: dist(x, y) = sqrt(dot(x, x) - 2 * dot(x, y) + dot(y, y)) This formulation has two advantages over other ways of computing distances. First, it is computationally efficient ...

WebAn obvious way to proceed would be to do a t test of the difference between each group mean and each of the other group means. This procedure would lead to the six comparisons shown in Table 1. Table 1. Six Comparisons among Means. false vs felt. false vs miserable. false vs neutral.
WebJan 22, 2024 · By “pairwise”, we mean that we have to compute similarity for each pair of points. That means the computation will be O (M*N) where M is the size of the first set of points and N is the size of the second set of points. The naive way to solve this is with a nested for-loop.
