Curriculum Learning of Bayesian Network Structures

 

Paper abstract

Bayesian networks (BNs) are directed graphical models that havebeen widely used in various tasks for probabilistic reasoning and causalmodeling. One major challenge in these tasks is to learn the BN structures fromdata. In this paper, we propose a novel heuristic algorithm for BN structurelearning that takes advantage of the idea of /emph{curriculum learning}. Ouralgorithm learns the BN structure by stages. At each stage a subnet is learnedover a selected subset of the random variables conditioned on fixed values ofthe rest of the variables. The selected subset grows with stages and eventuallyincludes all the variables. We prove theoretical advantages of our algorithmand also empirically show that it outperformed the state-of-the-art heuristicapproach in learning BN structures.
