Abstract: The present application discloses a method for detecting cigarette appearance defects based on variational Bayesian inference. In a cigarette appearance defect detection scenario, in order to solve the problem that a current point estimation-based machine learning algorithm leads to an overconfidence decision in a data scarcity area, the present application proposes a variational inference-based Bayesian method to improve a SSD backbone network. The present application can improve the accuracy of defect detection without losing the processing speed, not only saving a large amount of manpower and material resources, but also effectively providing reliable technical support for finding the root causes of defect types. Thus, it achieves intelligent quality risk management and control in a cigarette production workshop.

Abstract: In a secure communication method, a terminal device receives downlink control information, where the downlink control information indicates whether the kth piece of data transmitted in the ith hybrid automatic repeat request (HARQ) process is newly transmitted. If the kth piece of data is newly transmitted, a random seed is updated. An updated random seed is used for security processing on the kth piece of data. Based on this solution, a network device indicates, to the terminal device by using the downlink control information, whether the scheduled kth piece of data is newly transmitted. When the kth piece of data is newly transmitted, the terminal device may update the random seed, thereby synchronizing the random seed with the network device.
