Although the above two methods own pretty good filtering performance when system noise and observation noise are non - gaussian , their filtering performance will descend or even diverge when non - gaussian distribution occurs 上述兩種方法在當系統噪聲和觀測噪聲滿足高斯分布特性的時候具有較好的濾波性能,而對于非高斯分布噪聲上述濾波方法的指標下降,甚至出現發(fā)散。
The article analyses whether the theory of emh market can explain some phenomena on capital market . we provide some evidence for the non - normal , non - gaussian distribution , auto - correlation , non - linear and heteroskedasticity character of stock price 文章就有效市場假說( emh )對現實資本市場的解釋能力進行了分析,發(fā)現我國股票市場的股價收益率序列具有非正態(tài)性、自相關性、非線性、異方差性等特點。
Based on unsupervised learning , sparse coding is suitable to describe images with non - gaussian distribution and can get rid of the high order redundancy among the image pixels . since the basis function of sparse coding has build - in clustering property , it increases the inter - class variations of the features 稀疏編碼是一種基于非監(jiān)督學習的算法,它適合描述具有非高斯分布的數據對象,能夠有效地消除圖像象素點之間的冗余,并具有內在的聚類特性。
Non - gaussian distribution and noniinear , auto - - correlation and heteroskedasticity character of stock price and return rates , presented that main factors leads to the failure of emh on chinese stock market is emotionai action , information - - based herding , over - - reaction and under - reaction to information of investors and noniinear , non - equiiibriurn propefty of stock market 提出有效市場理論失靈的主要原因是投資者的非理性行為,信息反映的羊群效應,投資者存在反應過度和反應不足現象,股票市場的非均衡特征和股票市場的非線性特征。
Based on survey data from some researches , dead load model and vehicle load model are presented in this paper . it is quite evidence that dead load model is gaussian distribution , and vehicle load is non - gaussian distribution , which operates general traffic and rush hour traffic states 本文在國內外各種調查資料的基礎上,分別引入恒荷載模型及車輛荷載模型,其中恒荷載呈正態(tài)分布:車輛荷載則為非正態(tài)分布,并將其分為一般運行狀態(tài)及密集運行狀態(tài)兩種情況,分別建立服役期最大值分布函數。
At last distribution functions of load modes in life service are presented . based on the resisting force model and load model , the limit state equations of rc bridge are formulated . according to the resisting force is time - dependent and vehicle load is the non - gaussian distribution , jc method is applied to calculate the time - dependent reliability index of rc bridge 在抗力衰減模型及橋梁荷載模型的基礎上,將可靠度理論引入橋梁結構的評定中,推導出了橋梁結構耐久性極限狀態(tài)方程,并根據耐久性極限狀態(tài)方程中抗力是時間的函數,以及車輛荷載為非正態(tài)分布的特點,應用當量正態(tài)法( jc法)編制相應的程序計算橋梁構件的時變可靠度指標。
