Jaccard Similarity

Jaccard index

The Jaccard index is a statistic used to measure the similarity and diversity of sample sets. It is defined as the size of the intersection divided by the size of the union of two sample sets, and can range from 0 to 1. It is widely used in computer science, ecology, genomics, and other sciences, and there are versions for bags and measures. The MinHash min-wise independent permutations locality sensitive hashing scheme can be used to efficiently compute an estimate of the Jaccard similarity coefficient.
