Aviation security check system on neural network risk assessment model 基于神经网络的民航安检系统风险评价研究
On this basis, an ideal evaluation mode is approached by establishing a BP neural network risk assessment model and using the MATLAB program to compute and simulate. 在此基础上,通过建立BP神经网络风险评价模型,运用MATLAB编程进行计算与仿真,得到了较为理想的评价模型。
The original defect of RBF neutral network would be overcome by factor analysis theory. Meanwhile, F-RBF neutral network comprehensive assessment model is set up to assess stock yield of listed companies in China. 利用因子分析理论,克服了径向基神经网络的原有缺陷,同时建立了F-RBF神经网络综合评估模型,并将此模型应用于我国上市公司股票的收益率评估。
Gray relational analysis model is used to determine the evaluation index weight vector and to improve the objectivity of index weights. Secondly, the paper puts forward network security threat assessment model based on gray fuzzy matrix. 采用灰色关联分析模型确定评估指标权重向量,提高指标权重的客观性。其次,提出了基于灰色模糊矩阵的网络安全威胁评估模型。
