In the structure learning of the largescale Bayesian network (BN) model for the coal mill process, taking the view of the problem that the decompositionbased method cannot guarantee the sufficient learning of abnormal state node neighborhood in the diagnosis model, this paper proposes a new BN structure learning method based on decomposition. Firstly, a sketch is constructed based on an ...
