摘要 提出了用无监督的自组织映射方法对金融数据进行聚类,并用平行坐标和交互式的圆形平行坐标方法在二维平面上表示出来。用这种方法形成清晰的可视化聚类结果,不仅有效地总结了数据特征,还提高了聚类的可视效果,从而便于发现数据的变化趋势。 This paper proposed an unsupervised SOM-based cluster method for dealing with financial data.The clustered result was visualized on two dimensions by using parallel coordinate and interactive circular parallel coordinate.With this method,it can form a clear visualization of the clustered result,improve the effect of visual clustering and enable user to reveal underlying patterns.
