WebOct 26, 2024 · Cosine similarity is a measure of similarity between two non-zero vectors. It is calculated as the angle between these vectors (which is also the same as their inner product). Well that sounded like a lot of technical information that may be new or … WebNov 18, 2024 · Cosine similarity is a measure of similarity between two non-zero vectors of an inner product space that measures the cosine of the angle between them. The cosine of 0° is 1, and it is less than 1 for any angle in the interval (0,π] radians. The Levenshtein distance is a string metric for measuring the difference between two sequences.
