英文摘要：

Driver fatigue recognition has great theoretical significance and applied value in reducing accidents and improving traffic safety.A novel method based on deep belief network and generative model is proposed for driver fatigue recognition.In order to represent fatigue effectively,fatigue features are extracted using deep belief network（DBN）from the facial image.The semi-supervised learning method for fatigue recognition based on generative model is proposed to solve the problem of small sample in recognition,which makes use of both the labeled and unlabeled samples.Experiments were performed on self-built database to test and evaluate the proposed method.The experiment results show that our method has higher recognition accuracy than other state-of-the-art methods.
