在傳統聚類演算法的基礎上，結合我們科學數據挖掘的應用對象?分子動力學數據，提出了迭代網格聚類演算法， k -平均和基於密度結合的聚類演算法，迭代過程中優化選擇中心點的k -平均方法，以及改進型的基於距離的聚類演算法等模式識別方法，能夠解決傳統演算法帶來的諸多問題（比如一些傳統的聚類演算法常常收斂于局部最優，發現都模式都趨近於球形，劃分方法中迭代次數過多帶來的效率問題） 。At the same time, we optimize the method by initializing the snmf with the spherical k - means and the nnls ( non - negative least squares ). by combination of snmf and the method lpi ( locality preserving indexing ), we get better performance in clustering accuracy
同時採用球形k -平均演算法和nnls （非負最小平方差）演算法的結果初始化snmf演算法以達到改進和優化snmf演算法的目的;通過結合snmf演算法與lp （ i局部保留索引）演算法以實現在無監督的方式下取得更準確聚類結果的演算法。The basic idea for hierarchy - based method is that creating and maintaining a tree of clusters and sub - clusters according to some kind of criterion to measure the distance of clusters, the procedure will be sloped until some terminal conditions are satisfied. hierarchical clustering method can be further classified into agglomerative and divisive hierarchical clustering, depending on whether the hierarchical decomposition is formed in a bottom - up or top - down fashion. most hierarchical clustering methods can produce the better results when the clusters are compact or spherical in shape. but they do not perform well if the clusters are any shape or there are outliers. a main reason is that the most hierarchical clustering methods employ medoid - based measurement as distance between clusters
基於層次方法的聚類的基本思想足：根據給定的簇間距離度量準則，構造利維護一棵由簇利子簇形成的聚類樹，直至滿足某個終結條件為止。根據層次分解是自底向上還是自頂向下形成，層次聚類方法可以分為凝聚的（ agglomerative ）和分裂的（ divisive ） 。人多數層次聚類演算法在緊密簇或球形簇結構下能夠產生較好的聚類效果。The thesis was originally intended to reveal magnetoresistance effect in two kinds of novel composites : ( 1 ) acicular cro2 / spherical insulating granular composite ; ( 2 ) cro2 granules coated with insulating polymer, respectively
