cosine distance
how can I calculate the cosine distance of |di, dj|. In example of cosine distance ||d1 - d2|| = 0.52 ???, where does it come from? The formula teach us to calculate the angle of 2 vectors, and the example is about distance?? I have tried to calculate but don't have the same result. --2001:16B8:13BD:7000:30DD:2390:228E:66F9 (discuss) 20:48, 8 December 2018 (UTC)
