WebNov 17, 2024 · Cosine similarity is for comparing two real-valued vectors, but Jaccard similarity is for comparing two binary vectors (sets). In set theory it is often helpful to see a visualization of the formula: We can see that the Jaccard similarity divides the size of the intersection by the size of the union of the sample sets.
