Discontinuous Wavelet Analysis and Mixed Cluster Analysis
气候序列不连续点的小波分析和混合聚类分析

We study the wavelet analysis and hybrid cluster analysis of discontinuous points, and explain that there are the shortcomings both in wavelet analysis and in nonparametric analysis. So, we detect each class discontinuities by means of wavelet analysis and hybrid cluster analysis. When the number of samples is great, Fisher algorithm has no hierarchical structures, and involves a mount of calculations. For maintaining hierarchical structure and gaining fast approach, we study each class of discontinuities by wavelet analysis and cluster anaysis. We present an algorithm and an experiment. From the result, we find that the method Performs well.
