hierarchical classification

Two dimension reduction methods of point evaluation technique and pedigree clustering analysis were applied to the large amount of calculation in the reliability analysis of structural systems.

本文采用系統可靠性理論對地震作用下的地下管線動力可靠性進行分析,并針對系統可靠性計算量大的難題,引入了PNET法(point evaluation technique)與譜系聚類分析法兩種降維方法,在保證精度的同時大大提高了計算效率,使對地下管線的系統可靠性分析達到實用化程度。

The hierarchical clustering method is applied to deal with the problem that the solution of MLS-SVM is lack of sparseness.

運用譜系聚類方法解決多核最小二乘支持向量機的解缺乏稀疏性的問題。

This method used the pedigree clustering algorithm to obtain the initial centers of classes,and then employed the k-means clustering algorithm to distill the main colors.

提出了先使用譜系聚類法獲得初始類心,然后用k-均值聚類法提取背景的主色的方法。
