Abstract: For the cognitive difficulties in network security when dealing with massive amounts of high-dimensional data, this paper proposes a method of visualization based on the improved right regular polygon of even sides. It takes the advantage of evaluation index for visual effect and correlation to rearrange dimension in order to optimize the display effect of dimension reduction. The experiments show that this method maintains the advantages of finding dimensional distribution information easily, and it overcomes the shortcomings of disorder of scatterplot and rare of presence information. It can help find cluster information effectively and facilitate data mining and analysis for administrator.

Key words: right regular polygon of even sides, visualization, dimension rearrangement, correlation coefficient, dimension reduction
