HOPE

This is a sample implementation of "Asymmetric Transitivity Preserving Graph Embedding"(KDD 2016).

Requirements

MATLAB R2014a

Usage

run embed_main.m with matlab

Input:
	A: N*N adjacency matrix (sparse)

	K: dimensionality of embedding space

	beta: decaying constant, default is 0.5 / spectral radius
    
Output:
    U: N*K left embedding matrix

	V: N*K right embedding matrix

	The high-order proximity (katz) matrix is approximated by U * V'
