摘要
In this paper, we present a multi-objective Discrete Particle Optimizer (DPSO) for the learning of Dynamic Bayesian Network (DBN) structures. The proposed method introduces a hierarchical structure consisting of DPSOs and a Multi-Objective Genetic Algorithm (MOGA). Groups of DPSOs find effective DBN sub-network structures and a group of MOGA finds whole of the DBN network structure. Through numerical simulations, the proposed method can find more effective DBN structures and can obtain them faster than the conventional method.
