ARMA模型時(shí)間序列分析法簡(jiǎn)稱為時(shí)序分析法,是一種利用參數(shù)模型對(duì)有序隨機(jī)振動(dòng)響應(yīng)數(shù)據(jù)進(jìn)行處理,從而進(jìn)行模態(tài)參數(shù)識(shí)別的方法。參數(shù)模型包括AR自回歸模型、MA滑動(dòng)平均模型和ARMA自回歸滑動(dòng)平均模型。這里給出了一個(gè)求出ARMA模型參數(shù)的MATLAB程序。

Accurate estimates of the autocorrelation or power spectrum can be obtained with a parametric model (AR, MA or ARMA). With automatic inference, not only the model parameters but also the model structure are determined from the data. It is assumed that the ARMASA toolbox is presen

The task of clustering Web sessions is to group Web sessions based on similarity and consists of maximizing the intra- group similarity while minimizing the inter-group similarity. The first and foremost question needed to be considered in clustering W b sessions is how to measure the similarity between Web sessions.However.there are many shortcomings in traditiona1 measurements.This paper introduces a new method for measuring similarities between Web pages that takes into account not only the URL but also the viewing time of the visited web page.Yhen we give a new method to measure the similarity of Web sessions using sequence alignment and the similarity of W eb page access in detail Experiments have proved that our method is valid and e幣cient.
