Computes the Jaccard distance between rows of a matrix and returns a sparse symmetric indicator matrix containing the entries with a distance of less than a given upper bound. Note that the diagonal is always 1.
jaccard_indicator(x, upper_bnd = 0.8)
A list of vectors describing a sparse lower triangular pattern matrix
Row indices
Column indices
the input matrix with vectors to be compared in the rows.
pairs with a Jaccard distance below this upper bound are returned as 1 while all others receive the entry 0.
