Comment on Which vector similarity metric should I use?Comments−messe3yEven ignoring vector magnitudes, wouldn't cosine distance as a measure of similarity only make sense if you're working with a convex set? That seems like it's far from a guarantee working in a high-dimensional space.−imaurerOP3yYes, cosine distance works best in convex or normalized sets. Thinking about adding this caveat. Thanks for the question.
