[英文釋義] The science and art of collecting,summarizing,and analyzing data that are subject to random variation. The term is also applied to the data themselves and to the summarization of the data.
The statistical fluctuation of counts in each channel can be reduced several times after disposed by wavelet de-noising, but the correlation of data between channels should be noticed 小波消噪后的譜每道上的計(jì)數(shù)統(tǒng)計(jì)漲落可降低至原來的幾分之一,但道計(jì)數(shù)數(shù)據(jù)間具有很強(qiáng)的相關(guān)性。
In chapter 1, the definition of data mining, the category of methods of data mining, the front of data mining and the deference and correlation of data mining and statistics are discussed detailed 在第一章數(shù)據(jù)挖掘方法概述部分,重點(diǎn)闡述了數(shù)據(jù)挖掘的定義、數(shù)據(jù)挖掘方法分類、數(shù)據(jù)挖掘方法研究現(xiàn)狀以及數(shù)據(jù)挖掘和統(tǒng)計(jì)學(xué)的區(qū)別與聯(lián)系。
The case studies were mainly on japan & russia, during the process, the author reviewed the characteristics on corporate governance & informal systems of the two countries, and particularly made historical & empirical study on how informal institutions influence corporate governance . because of correlation of data and the difficulties in collecting the related data, the case studies were qualitative 在實(shí)證研究時(shí),筆者考察了兩國公司治理和非正式制度的典型特征,特別對(duì)非正式制度對(duì)公司治理的影響進(jìn)行了歷史的實(shí)證研究,考慮到數(shù)據(jù)的相關(guān)性和相關(guān)數(shù)據(jù)獲取的困難,實(shí)證研究以定性分析為主。
We use the correlation of data between the neighbor scan lines to get the overlay pixel number, and then remove the overlay data . the bilinear interpolation method is applied to assign the pixels with the overlap data . the result shows that the data overlay phenomenon is removed, image quality is improved, and pixel value has been enhanced 此外,對(duì)于modis遙感影像中存在的邊緣區(qū)域數(shù)據(jù)重疊問題,則利用數(shù)據(jù)間的相關(guān)性計(jì)算條帶間各列像元的重疊數(shù)量,然后刪除重復(fù)部分,并經(jīng)灰度重采樣后得到結(jié)果數(shù)據(jù),實(shí)驗(yàn)表明影像數(shù)據(jù)的重疊現(xiàn)象明顯消除,從而改善了影像的質(zhì)量,增強(qiáng)了數(shù)據(jù)的使用價(jià)值。
