The method includes the following steps: firstly, a spherical neighborhood of present sample points is established by using the geometric spherical-modelling theory and all the sample points contained in the spherical neighborhood are adopted as candidate neighbor points, thus not only preserving the effectivity of the dimension reduction capability when data sets are sparse but also getting the advantages of low-sensitivity to isolated points and good stability of the preserved topological structure; then a data relevance matrix more matching semantics can be obtained by relevance measurement based on route clusters to update the candidate neighbor points in the spherical neighborhood and optimize the regular neighborhood space of the present sample points, thus improving the phenomenon that the dimension reduction of sample sets provided with folded curved faces is apt to suffer the integrated-structure distortion in case of heterogeneous data distribution.

首先利用几何开球原理建立当前样本点的球状邻域，将包含在球状邻域内的所有样本点作为候选近邻点，不但能够保持在数据集稀疏情况下的降维性能的有效性，而且具有对孤立点敏感性不高、保留拓扑结构稳定性好的优点。然后利用基于路径聚类的相关性度量得到更符合语义的数据相关性矩阵，用来对球状邻域内的候选近邻点进行更新，优化当前样本点的规则邻域空间，改善了当数据不均匀分布时在带有折叠弯曲面的样本集上降维容易出现整体结构扭曲的现象。

With this measure, a new method for calculating the minimum embedding segment dimension of a linear segment sequence is proposed. With this method, the MESD of the linear segment representation of a real financial time series is calculated.

该方法实现了对时间序列的基于基本变化形态的合理分割，保证转换后的每一个符号都能代表一个基本的、相对独立的变化模式，为最终挖掘结果的有效性和可视化提供保证；同时，针对数据挖掘数据量大，对算法的计算效率和在线性能要求高的特点，提出了一个实现时间序列分段线性化的增量式更新算法；并利用神经网络模糊聚类算法实现了完全数据驱动的在线聚类分析。
