摘要。分布熵(DistEn)是衡量时间序列复杂性的有效指标。本文将分布熵法与移动窗口技术相结合,提出了移动分布熵(M-DistEn)方法。将移动切割数据分布熵(MC-DistEn)与移动移除窗口相结合,提出了移动切割数据分布熵(MC-DistEn)方法。在M-DistEn方法的基础上,提出了移动加权分布熵(MW-DistEn)方法。将这三种分布熵方法用于识别不同参数的混合Logistic映射序列的混沌状态。结果表明,M-DistEn方法只能识别序列的前三个混合状态,不能准确识别序列的后两个混沌状态,具有一定的局限性。MC-DistEn方法可以准确识别序列的四种不同混沌状态,但由于运动去除窗口大小的影响,DistEn值波动较大,对序列状态变化的位置判断不够准确。与M-DistEn方法和MC-DistEn方法相比,MW-DistEn方法不仅能准确识别不同混沌状态,而且对序列状态变化位置的判断更准确,DistEn值也更稳定,具有良好的应用前景。
Abstract. Distribution entropy (DistEn) is an effective index to measure the complexity of time series. In this paper, the moving distribution entropy (M-DistEn) method is proposed by combining the distribution entropy method with the moving window technology. The moving cut data-distribution entropy (MC-DistEn) method is proposed by combining the DistEn with the moving removal window. Based on the M-DistEn method, moving weighted distribution entropy (MW-DistEn) is proposed. These three distribution entropy methods are used to identify the chaotic state of mixed Logistic map sequences with different parameters. The results show that the M-DistEn method only recognizes the first three mixed states of the sequence, and it cannot accurately recognize the last two chaotic states of the sequence, so it has certain limitations. The MC-DistEn method can accurately identify the four different chaotic states of the sequence, but the DistEn value greatly fluctuates due to the influence of the size of the moving removal window, and the position judgment of sequence state change is not accurate enough. The MW-DistEn method not only accurately recognizes different chaotic states, but also is more accurate in judging the position of sequence state changes and more stable in DistEn value than the M-DistEn method and MC-DistEn method, thereby it has a good application prospect.
