| 摘 要： | 处理数量巨大且富含多维信息的数据正成为人们关注的热点,可视化技术为我们分析和处理海量信息提供了新的手段。提出基于弹性网络图的多维信息可视化方法,详细阐述了弹性网络图的实现原理及其在多维信息可视化中的应用。弹性网络图把原始的多维信息在预先定义好的图上训练,使得图的能量最小,结果使原始的多维数据点聚集在能量最小的网络图节点周围。弹性网的构造是在与原始信息维度相同的空间中进行的,多维信息在网络图的内部坐标上投影,从而保证多维信息非线性降维后与原始信息之间的一致性。最后用弹性网络图方法对2003年中国非典的多维信息进行了可视化分析,验证了该方法的实用性。

| Abstract: | Processing massive and multi-dimensional information is a research hot in recent years and visualization technology provides a new approach to analyze and understand massive information better.A multi-dimensional visualization method was brought out based on Elastic Net Map(ENM).The principles of ENM and its multidimensional information visualization application were introduced in detail.Multidimensional information trained on a predefined graph though ENM,and the trained data were distributed around the re... |
