Fuzzy tensors encode to what extent n-ary predicates are satisfied. The disjunctive box cluster model is a regression model where sub-tensors are explanatory variables for the values in the fuzzy tensor. In this article, the most informative patterns according to that model, with high areas times squared densities, are grown by hill-climbing from fragments of them, that a complete algorithm provides. At every iteration, an optimization problem (or its linear relaxation) is solved thanks to integer linear programming (or greedily). A forward selection then chooses among the discovered patterns a non-redundant subset that fits, but does not overfit, the tensor. Experiments show the proposal discovers high-quality patterns and outperforms state-of-the-art approaches when applied to 0/1 tensors, a special case.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
