中文摘要：

针对现有维度排序方法较少考虑到用户参与的问题，文中提出基于可交互相关性矩阵的维度重排径向坐标可视化方法．采用考虑到径向坐标可视化（RadViz）特性、拥有可变参数的层次聚类算法推荐初始的维度顺序，提供展示算法结果的系统树图用于指导用户交互式地调整、选取、删除维度，进行特征子集选择．实验表明，文中方法具有较好的交互性，注重用户体验，减轻RadViz中的投影点重叠问题．

英文摘要：

In the existing dimension reordering algorithms, the interactive functions allowing users to perform order navigation or reorder operations are rarely taken into account. Aiming at this problem, a navigation- guided correlation matrix is proposed for users to interactively reorder dimensions in radial visualization （RadViz）. A hierarchical clustering algorithm with configurable parameters is specially designed for RadViz to recommend the initial dimension order. The dendrogram of results is employed to help users interactively reorder, select and delete dimensions for feature subset selection. Experiments show that the proposed method is interactive, user-friendly and helpful for alleviating the overlapping problem of data projections in RadViz.
