Generative Structure Learning for Markov Logic Networks Based on Graph of Predicates

Quang-Thang Dinh, Matthieu Exbrayat, Christel Vrain

Abstract: In this paper we present a new algorithm for generatively learning the structure of Markov Logic Networks. This algorithm relies on a graph of predicates, which summarizes the links existing between predicates and on relational information between ground atoms in the training database. Candidate clauses are produced by means of a heuristical variabilization technique. According to our first experiments, this approach appears to be promising.
