jaccard_indicator_comp: Perform the computations for thresholded Jaccard distance

In scregclust: Reconstructing the Regulatory Programs of Target Genes in scRNA-Seq Data

Perform the computations for thresholded Jaccard distance

Description

Perform the computations for thresholded Jaccard distance

Usage

jaccard_indicator_comp(gs, eps)

Arguments

gs	a list of integer vectors, one for each row, giving the column indices of the non-zero elements of the row or NULL if the whole row is empty.
eps	an upper bound on the Jaccard distance (1 - eps becomes a lower bound on the Jaccard similarity)

Details

This function is optimized for sparse matrices and computes the pairwise Jaccard distances between the rows of the input matrix. Note that the actual distance is not saved. Instead, a threshold (eps) is supplied and an indicator matrix is returned, with a one indicating that the distance is smaller than eps (equivalently, the Jaccard similarity is larger than 1 - eps).

Value

A list with row and column indices in the #row x #row indicator matrix specifying which rows in the original matrix had a distance of at most eps.
