随着一类具有时变但稳定频率的新型自持续振荡器的发展,现在制定了这些系统的逆方法。我们展示了如何在单变量时间序列中安排观测数据来识别这样的系统。该方法利用了小波变换的时频域信息和最近发展起来的贝叶斯推理方法。此外,还引入了一套称为相位涨落分析的方法,通过直接分析观测到的扰动的统计量来检测新一类系统的定义性质。我们将这些方法应用于数值例子,但也进一步阐述了心脏系统。
Following the development of a new class of self-sustained oscillators with a time-varying but stable frequency, the inverse approach to these systems is now formulated. We show how observed data arranged in a single-variable time series can be used to recognize such systems. This approach makes use of time-frequency domain information using the wavelet transform as well as the recently developed method of Bayesian-based inference. In addition, a set of methods, named phase fluctuation analysis, is introduced to detect the defining properties of the new class of systems by directly analyzing the statistics of the observed perturbations.We apply these methods to numerical examples but also elaborate further on the cardiac system.
