compose_coarsening: Compose Two Coarsening Passes

In bbuchsbaum/graphweights: Constructing Adjacency Matrices Based on Spatial and Feature Similarity

Compose Two Coarsening Passes

Description

Given the results of two consecutive passes of the REC coarsening, this function composes them to produce a single equivalent coarsening mapping and corresponding coarsened matrices.

Usage

compose_coarsening(pass1, pass2)

Arguments

pass1	A list containing 'C', 'W_c', 'L_c', and 'mapping' from the first coarsening pass.
pass2	A list containing 'C', 'W_c', 'L_c', and 'mapping' from the second coarsening pass.

Value

A list with elements:

C_final

The final coarsening matrix mapping from the original graph to the final coarsened graph.

W_c_final

The final coarsened adjacency matrix.

L_c_final

The final coarsened Laplacian matrix.

mapping_final

An integer vector mapping original vertices directly to the final coarsened vertices.

Examples

# Suppose you have run:
# result1 <- rec_coarsen(W, T=..., ...)
# result2 <- rec_coarsen(result1$W_c, T=..., ...)
# Now compose:
# composed_result <- compose_coarsening(result1, result2)
