In ANF: Affinity Network Fusion for Complex Patient Clustering

Description

Calculate k-nearest-neighbor graph from affinity matrix and normalize it as transition matrix

Usage

kNN_graph(W, K)

Arguments

W	affinity matrix (its elements are non-negative real numbers)
K	the number of k nearest neighbors

Value

a transition matrix of the same shape as W

Examples

D = matrix(runif(400),20)
W = affinity_matrix(D, 5)
S = kNN_graph(W, 5)
