  5. Design of reasoning network and nonstationary model system for detecting network traffic anomalies

    因果網的非穩態流量異常檢測系統設計
  6. Empirical analysis show that hierarchicalstructure panel data analysis model is the better one. finally, the dissertation study unit root test and cointegration of panel data set anddiscuss nonstationary of gdp and export annul data from 1992 to 2004 in the prc ’ sprovince, cities, and autonomous regions. empirical analysis show that the panel datahas a unit root, so it is nonststionary

    並且考慮到中國內地省區市1992年至2004年的年度國內生產總值與對外出口貿易總額的面板數據集在中國內地東部、中部和西部的差異而設定了包括東部、中部和西部三個頂層效應以及各省區市的底層嵌套效應，利用建立的兩層嵌套面板數據模型對多層嵌套面板數據集做了實證分析，得到了較好的兩層嵌套擬合模型。
  7. In addition, we proposed the posterior union model ( pum ), which improves over the conditional union model by retaining the advantage of requiring no identity of the noisy components, and by additionally offering a means of optimally estimating the model order, therefore enhancing the capability of the model for dealing with nonstationary noise

    最終本文提出了語音增強結合pum模型的一種新的語音抗噪方法，並且基於這種新方法我們從高識別率和低成本較高識別率兩方面出發，構建了改進型ctranc結合pum新模型和改進型重復wiener濾波結合pum新模型。
