adj_conv {ConsensusClustering}

Convert adjacency function to the affinity matrix

Description

Convert adjacency function to the affinity matrix

Usage

adj_conv(adj.mat, alpha = 1)

Arguments

adj.mat

Adjacency matrix. The elements must be within [-1, 1].

alpha

soft threshold value (see details).

Details

adj = exp(-(1-adj)^2/(2*alpha^2)) ref: Luxburg (2007), "A tutorial on spectral clustering", Stat Comput

Value

the matrix if affinity values.

Examples

Adj_mat = rbind(c(0.0,0.9,0.0),
                c(0.9,0.0,0.2),
                c(0.0,0.2,0.0))
adj_conv(Adj_mat)
