A … WebAug 8, 2015 · Correlation as distance measure. If you preprocess your data ( n observations, p features) such that each feature has μ = 0 and σ = 1 (which disallows constant features!), then correlation reduces to cosine: Corr ( X, Y) = Cov ( X, Y) σ X σ Y = E [ ( X − μ X) ( Y − μ Y)] σ X σ Y = E [ X Y] = 1 n X, Y . Under the same conditions ...
