0° Means Besties, 90° Means Strangers: The Math Behind Cosine Similarity

with Vinod Krishnan

About This Session

Cosine Similarity is like the social network of vectors—it measures how close two points are based on the angle between them. A 0° angle? Total BFFs, perfectly aligned. A 90° angle? Complete strangers, no common ground. It’s the secret sauce behind recommendations, NLP, and clustering, helping machines figure out who’s vibing and who’s not. Math has never been so… social.
