Compute indicator matrix of pairwise distances smaller than threshold

Description

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.

Usage

jaccard_indicator(x, upper_bnd = 0.8)

Arguments

x	the input matrix with vectors to be compared in the rows.
upper_bnd	pairs with a Jaccard distance below this upper bound are returned as 1 while all others receive the entry 0.

Value

A list of vectors describing a sparse lower triangular pattern matrix

i	Row indices
j	Column indices
