%X 摘要 针对传统态势评估方法权值确定困难、大规模数据处理和特征提取能力不足的问题，结合当前空战数据特征，将深度置信网络（DBN）应用于近距空战态势评估。通过密度峰值算法对空战特征数据进行聚类分析，并结合态势函数和专家判读进行修正，建立标准空战态势样本库；以重构误差和测试错误率为基础，建立网络拓扑结构和最优参数确定方法，提高模型的训练效率，并通过样本数据，对模型进行训练和验证。实验表明，模型态势分类正确率达到92.7%，模型运行时间满足应用需求，实例评估结果与客观态势一致性强。<br>Abstract：Considering the difficulty in parameter setting, weakness of traditional situation assessment methods in processing and feature extraction of big data, feature of air combat data, applications of deep belief network (DBN) to close-range air combat situation assessment are discussed. A sample library of combat situation was constructed. The data were clustered using density peaks algorithm, and the results were revised by specialists of air combat and traditional functions. Then the model of deep belief network was constructed. According to the standard of test and reconstruction error, the network topology structure and optimal parameters were determined. The model was trained by the data from the sample library. Experimental results show that the model's situation classification accuracy reaches to 92.7%, and its running time meets the application requirements. Analysis of the practical example verified the feasibility of the DBN model.
