WebbAssignment 3 September 18, 2008. 2.6.18. This exercise compares and contrasts some similarity and distance measures. (a) For binary data, the L1 distance corresponds to the Hamming disatnce; 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. Webb1. Simple Matching and Jaccard Coefficients SMC = number of matches / number of attributes = (n11 + n00) / (n01 + n10 + n11 + n00) J = number of 11 matches / number of not-both-zero attributes values = (n11) / (n01 + n10 + n11) 2.Cosine Similarity Jika d 1 and d 2 adalah dua buah dokumen vektor, maka:

WebbThe simplest type of similarity measure is the matching coefficient. For two objects i and i ′ and attribute j: The matching coefficient is the mean of the s -values for all m attributes (30.13) This means that one counts the number of attributes for which i and i ′ have the same value and divides this by the number of attributes.
