英文摘要：
We propose a combination of cluster analysis and stochastic process analysis to characterize high-dimensional complex dynamical systems by few dominating variables. As an example, stock market data are analyzed for which the dynamical stability as well as transitions between different stable states are found. This combined method also allows to set up new criteria for merging clusters to simplify the complexity of the system. The low-dimensional approach allows to recover the high-dimensional fixed points of the system by means of an optimization procedure.

中文摘要：
我们提出了一种聚类分析和随机过程分析相结合的方法，用较少的控制变量来描述高维复杂动力系统。作为一个例子，对股票市场数据进行分析，发现其动态稳定性以及不同稳定状态之间的转换。这种组合方法还允许为合并集群设置新的标准，以简化系统的复杂性。低维方法允许通过优化程序恢复系统的高维不动点。
