Two primary mathematical tools used in this dissertation are principal component analysis ( pca ) and blind signal analysis ( bsa ) , which are both data - driven methods . pca is not only used as feature extracting method ( where process variables are subjected to multivariate normal distribution ) , but also as a tool for dimension reduction ; bsa is used to extract independent features or process blind source signals from process information in information theory sense , which is more effective than pca in describing the process
主元分析方法不僅作為一種過程特征的提取方法(在過程信息服從多元正態(tài)分布的情況下) ，而且也作為一種過程數(shù)據(jù)降維的主要工具(在過程盲源信號提取的情況下) ；盲源信號分析是從信息論的角度，從過程信息中提取出盡可能獨立的過程特征信號或過程原始信源信號，它具有比主元分析更好的刻畫過程運行特征的性能。
Computer aided engineering quantity information extracting is still far from the aim after almost twenty years " research , though some extracting methods have been developed and applied in practice , such as " data exchange file " and " drawings input " , etc . the key problem is that the existing methods and computer aided architecture design ( caad ) are not well integrated
計算機輔助建筑工程量信息獲取技術(shù)經(jīng)過近二十年的研究，形成了基于數(shù)據(jù)交換文件、圖形輸入等方法，并在實際中得到了較廣泛的應(yīng)用，但這些方法離根本解決工程量信息自動獲取的目標(biāo)還相當(dāng)遙遠。咎其根本原因在于現(xiàn)有的工程量信息獲取方法和計算機輔助建筑設(shè)計沒有很好地集成和形成一體化。
