WebQuestion: a) For binary data, the L1 distance corresponds to the Hamming distance that is, the number of bits that are different between two binary vectors. The Jaccard similarity is a measure of the similarity between two binary vectors. Compute the Hamming distance and the Jaccard similarity between the following two binary vectors. x = 0101010001 y = …
