Numerical measure of how different two data objects are range from 0 (objects are alike) to ∞ (objects are different) Proximity. refers to a similarity or dissimilarity. WebNote that because the cosine similarity uses the inner product of normalised vectors, it only gives a relative comparison of two vectors, not an absolute one: the cosine similarity between \(\mathbf x\) and \(\mathbf y\) is the same as the similarity between \(\mathbf x\) and \(a\mathbf y\) for any positive constant \(a\).
