Non-Bayesian graph matching without explicit compatibility calculations

Abstract

This paper introduces a novel algorithm for performing Attributed Graph Matching (AGM) . A salient characteristic of the Interpolator- Based Kronecker Product Graph Matching (IBKPGM) algorithm is that it does not require the explicit calculation of compatibility values between vertices and edges, either using compatibility functions or probability distributions. No assumption is made about the adjacency structure of the graphs to be matched. The IBKPGM algorithm uses Reproducing Kernel Hilbert Space (RKHS) interpolator theory to obtain an unconstrained estimate to the Kronecker Match Matrix (KMM) from which a permutation sub-matrix is inferred.
