Abstract  Averaged onedependence estimators (AODE) is an important Bayesian learning method. However, in AODE all outputs of the superparentonedependence estimators (SPODEs) are equally considered, which may bring bad influences to the final results. In this paper, every SPODE is viewed as a generative model, and the model likelihood is used to measure its performance. Then, a new approach, named modellikelihood based superparentone dependence estimator (LODE), is proposed which integrates the SPODEs based on model likelihood. Compared with AODE, LODE significantly improves the classification performance with only a slight increase in computation.
