A Delayed Column Generation Strategy for Exact k-Bounded MAP Inference in Markov Logic Networks

Abstract
The paper introduces k-bounded MAP infer- ence, a parameterization of MAP inference in Markov logic networks. k-Bounded MAP states are MAP states with at most k ac- tive ground atoms of hidden (non-evidence) predicates. We present a novel delayed col- umn generation algorithm and provide em- pirical evidence that the algorithm efficiently computes k-bounded MAP states for mean- ingful real-world graph matching problems. The underlying idea is that, instead of solv- ing one large optimization problem, it is often more efficient to tackle several small ones.
