ABSTRACT
In this paper, a method of large multidimensional data visualization that associates the multidimensional scaling (MDS) with clustering is modified and investigated. In the original algorithm, the visualization process is divided into three steps: the basis vector set is constructed using the k-means clustering method; this set is projected onto the plane using the MDS algorithm; the remaining data set is visualized using the relative MDS algorithm. We propose a modification which differs from the original algorithm in the strategy of selecting the basis vectors. In our modification, the set of basis vectors consists of vectors that are selected from k clusters in a new way. The experimental investigation showed that the modification exceeds the original algorithm in visualization quality and computational expenses.

    We examine the use of triadic distances as a basis for multidimensional scaling (MDS). The MDS of triadic distances (MDS3) and a conventional MDS of dyadic distances (MDS2) both give Euclidean representations. Our analysis suggests that MDS2 and MDS3 can be expected to give very similar results,...

    Findings on both attractiveness and memory for faces suggest that people should perceive more similarity among attractive than among unattractive faces. A multidimensional scaling approach was used to test this hypothesis in two studies. In Study 1, we derived a psychological face space from...

In two studies, we modeled the locations of attractive and unattractive Caucasian,...
