Since em algorithm has certain good convergence properties and can be widely applied , it has attracted many researchers from statistics , other applied science and engineering 由于具有很好的收斂性質(zhì)和廣泛的應(yīng)用背景, em算法一直受到統(tǒng)計學(xué)和其它應(yīng)用科學(xué)及工程界的廣泛重視。
The terrence donnelly centre for cellular and biomedical research dccbr at the university of toronto was opened in 2005 as a joint project of the faculties of medicine , pharmacy and applied science and engineering , to foster interdisciplinary collaboration in human genome research 3 .多倫多大學(xué)的dccbr中心于2005年啟用,為醫(yī)學(xué)院藥理學(xué)院及應(yīng)用科學(xué)及工程學(xué)院的合作項目,以促進跨學(xué)科的基因研究工作。
In many fields , such as remote sensing , nuclear medical , computer tomography , geophysical prospecting , groundwater hydrology , global ocean modeling , image processing , tumor detection , nondestructive detection , the objective of applied sciences and engineering is the recovery of the original signal given a collection of noisy observations of the original signal ; we call these problems inverse problem 在遙感技術(shù)、核醫(yī)療技術(shù)、計算機斷層掃描( ct )技術(shù)、地質(zhì)勘探、地下水文學(xué)、電磁輻射、圖像恢復(fù)和重構(gòu)、腫瘤檢測、非破壞性檢測等科學(xué)研究和工程實踐中,經(jīng)常需要根據(jù)一組觀測到的數(shù)據(jù)來估計目標(biāo)的真實信號,而觀測到的數(shù)據(jù)往往是真實信號經(jīng)模糊、失真和加噪等過程后所得的輸出信號,通常稱這類問題為逆問題。
