对映映射

Firstly, sample data stream by two neighbor windows of given length. Then the sampling data is projected to normalized high dimension feature space and the two minus hypersphere models of two window sampling data sets are constructed respectively. Finally, detect change by computing cosine of inclination angle of two centrals of hypersphere.

该算法首先以给定长度的两相邻时间窗口对数据流取样，然后以支持向量数据描述方法将这两相邻时间窗口取样的数据流子集映射到规范化的高维特征空间，并分别建立描述这两相邻时间窗口取样数据流子集映像的最小超球模型，最后通过计算两超球之间的球心矢量的夹角的余弦，度量该两相邻时间窗口取样数据流子集的相似性检测模式变化。

Based on the common symbolic dynamic method, a novel time-varying symbolic dynamic method is proposed. The Logistic map is used to test the properties of the method.
