摘要
用Boltzmann统计状态熵度量怪引子的展开程度,从而提出选取延迟时间变量的第一极大熵准则。实际使用时,仅需等价地计算重构图所及的状态个数。通过Rossler吸引子的重构说明了本文方法的有效性。
The Boltzmann's entropy is used to measure the spreading extent of strange attractors in this paper. The first local maximum of entropy function is suggested as a criterion for selecting delay time in reconstruction of strange attractors. In practical applications, it is simply equivalent to counting boxes the system states reached. The effectiveness of the proposed approach is illustrated through reconstructing Rossler at-tractor.
