TIMERS

This is a sample implementation of "Community Preserving Network Embedding"(AAAI 2017).

Requirements

MATLAB 

Usage

run MNMF.m with matlab

function [U, M, H, C, L] = MNMF(S, M, U, H, C, B1, B2, alpha, beta, lambda)
% The demo is written by Xiao Wang ([email protected]), and the details of the algorithm can be
% found in "Community Preserving Network Embedding" (AAAI 2017).
%%--------------input-----------------
% S: S1+5*S2, the first- and second-order proximities (n-by-n);
% M: the initialized basis matrix (n-by-m);
% U: the initialized representations of nodes (n-by-m);
% H: the initialized community indicator matrix (n-by-k);
% C: the initialized representations of communities (k-by-m);
% B1: the adjacency matrix B1(i,i)=0 (n-by-n);
% B2: (k_i*k_j)/2e (n-by-n);
% alpha, beta, lambda: the values of parameters, usually alpha and beta need to be tuned and we can set lambada = 1e9;
%%-------------output------------------
% U: the optimal representations of nodes;
% M: the optimal basis matrix;
% H: the optimal community indicator matrix;
% C: the optimal representations of communities;
% L: the final values of objective function.
