Abstract: In order to improve the quality anomaly detection performance of industrial products based on complex data features, an intelligent anomaly detection method FE-GRBM for industrial product quality inspection is proposed based on the comprehensive advantages of Gaussian Restricted Boltzmann machine in nonlinear modeling and computational complexity. Specifically, the free energy based model training and detection strategies are studied, using the mathematical relationship between free energy and natural logarithm of edge probability of GRBM. The method are verified by the quality inspection of cigarette products in real case. The results show that the average performance of FE-GRBM is 0.29 higher than the highest score among the three traditional methods, and 0.04 higher than that of RE-GRBM, which shows the superiority of our method.
