The iteration formula and determination of iteration step are set up according to a priori information of rock and concrete 建立了考慮先驗信息的修正高斯-牛頓算法的迭代格式和迭代步長的確定方法。
Blind beamforming ( bbf ) is concerned with the reconstruction of source signals from the outputs of a sensor array without a priori information of the direction of the desired source , relying instead on signal characteristics and array structures 盲波束形成無需知道目標波達方向等先驗信息,直接利用信號、基陣自身的特性,就可從基陣的輸出采樣信號中恢復出期望信號。
A method based on gene expression programming ( gep ) for identifying the nonlinear system model is presented , which makes up the insufficiency that traditional identification methods need much a priori information , and has a tidier and more efficient system model expression mode than genetic programming ( gp ) 摘要給出了利用基因表達編程( gep )進行非線性系統辨識的方法,彌補了傳統辨識方法需要過多預知信息的不足,有著比遺傳編程( gp )更簡潔有效的系統模型結構表達方式。
Firstly , the problem of multiple a priori information fusion has been studied under the condition of the same test environment , such as the consistency test of a priori information , the credibility analysis of a priori information , the calculation of credibility with information likelihood rate , the expression of fusion posterior distribution based on the credibility of multiple a priori information 首先,研究了同種環境下多源驗前信息的融合問題,如驗前信息的相容性檢驗、驗前信息的可信性分析、基于信息似然比的可信度計算、基于多源驗前信息可信度的融合驗后分布表示等。
