WebJul 18, 2024 · Cosine is not affected by the vector lengths, so switching from dot product will cause the similarities for all popular videos to decrease. No change. Since cosine is … WebApr 11, 2015 · The cosine similarity metric finds the normalized dot product of the two attributes. By determining the cosine similarity, we would effectively try to find the cosine of the angle between the two objects. The cosine of 0° is 1, and it is less than 1 for any other angle. It is thus a judgment of orientation and not magnitude.
