Entropy-based Pruning for Learning Bayesian Networks using BIC

no code implementations19 Jul 2017 Cassio P. de Campos, Mauro Scanagatta, Giorgio Corani, Marco Zaffalon

For decomposable score-based structure learning of Bayesian networks, existing approaches first compute a collection of candidate parent sets for each variable and then optimize over this collection by choosing one parent set for each variable without creating directed cycles while maximizing the total score.

Approximation Complexity of Maximum A Posteriori Inference in Sum-Product Networks

1 code implementation17 Mar 2017 Diarmaid Conaty, Denis D. Mauá, Cassio P. de Campos

We discuss the computational complexity of approximating maximum a posteriori inference in sum-product networks.

Global Sensitivity Analysis for MAP Inference in Graphical Models

no code implementations NeurIPS 2014 Jasper De Bock, Cassio P. de Campos, Alessandro Antonucci

We study the sensitivity of a MAP configuration of a discrete probabilistic graphical model with respect to perturbations of its parameters.
