WebOct 6, 2024 · The dissimilarity between the two vectors ‘x’ and ‘y’ is given by – ∴ Dis (x, y) = 1 - Cos (x, y) = 1 - 0.49 = 0.51 The cosine similarity between two vectors is measured in ‘θ’. If θ = 0°, the ‘x’ and ‘y’ vectors overlap, thus proving they are similar. If θ = 90°, the ‘x’ and ‘y’ vectors are dissimilar.
