This paper proposes an evidence network reasoning recognition method based on a cloud fuzzy belief, which takes advantage of the evidence network in uncertainty processing. The method constructs a hierarchical structure model of an evidence network, measures the degree of correlation between nodes using the MIC method, generates beliefs based on the cloud model, and realizes target recognition under uncertain conditions through evidence network reasoning. Simulation results demonstrate that the proposed method can handle random uncertainty and cognitive uncertainty simultaneously, overcome the limitation of traditional methods in hierarchical recognition, and effectively utilize sensor information and expert knowledge for deep cognition of the target intention.
Uncertainty is widely present in target recognition, and it is particularly important to express and reason the uncertainty. Based on the advantage of the evidence network in uncertainty processing, this paper presents an evidence network reasoning recognition method based on a cloud fuzzy belief. In this method, a hierarchical structure model of an evidence network is constructed; the MIC (maximum information coefficient) method is used to measure the degree of correlation between nodes and determine the existence of edges, and the belief of corresponding attributes is generated based on the cloud model. In addition, the method of information entropy is used to determine the conditional reliability table of non-root nodes, and the target recognition under uncertain conditions is realized afterwards by evidence network reasoning. The simulation results show that the proposed method can deal with the random uncertainty and cognitive uncertainty simultaneously, overcoming the problem that the traditional method has where it cannot carry out hierarchical recognition, and it can effectively use sensor information and expert knowledge to realize the deep cognition of the target intention.
