The simple matching coefficient (SMC) or Rand similarity coefficient is a statistic used for comparing the similarity and diversity of sample sets. Given two objects, A and B, each with n binary attributes, SMC is defined as: where: is the total number of attributes where A and B both have a value of 0. is the total number of attri… WebbThe dissimilarity based on these attributes by the Jaccard Coefficient is computed as follows: $$ d(i,j) = \frac {b+c}{a+b+c} \implies 1- sim(i,j) $$ 1.2. Python Example Below, a function is defined to compute Jaccard similarity between two binary vectors. You can also find this builtin to scikit-learn, under sklearn.metrics.jaccard_score.
