Layer Similarity

Computes similarity between two network layers.

Usage

layer_similarity(
  A1,
  A2,
  method = c("jaccard", "overlap", "hamming", "cosine", "pearson")
)

lsim(A1, A2, method = c("jaccard", "overlap", "hamming", "cosine", "pearson"))

Arguments

A1

First adjacency matrix

A2

Second adjacency matrix

method

Similarity method: "jaccard", "overlap", "hamming", "cosine", "pearson"

Value

Numeric similarity value

Examples

A1 <- matrix(c(0,1,1,0, 1,0,0,1, 1,0,0,1, 0,1,1,0), 4, 4)
A2 <- matrix(c(0,1,0,0, 1,0,1,0, 0,1,0,1, 0,0,1,0), 4, 4)

layer_similarity(A1, A2, "jaccard")  # Edge overlap
#> [1] 0.4
layer_similarity(A1, A2, "cosine")   # Weight similarity
#> [1] 0.5773503
