Abstract

The results of information analysis of the time series of satellite monitoring of the state of the interplanetary magnetic field provided by the database of the Goddard Space Flight Center. In the arsenal of analysis methods, the main attention is paid to the control of nonextensive properties when scaling time samples created on the basis of the 2001–2022 time series. The reconstruction of the modality of the probability-distribution function for the components of the interplanetary magnetic field in the considered ensemble of realizations is demonstrated. The results of the reconstruction of the kinetics of the Shannon–Boltzmann–Gibbs, Tsallis, and Rényi entropy measures are presented. In a nonextensive approximation, the influence of q-deformation of the phase space on the stochastic regimes of the system under study. In this work, for the first time, the kinetics of information discrepancy and the kinetics of entropy measures of the ensemble of realizations of the values of the interplanetary magnetic field are studied together. The need for approval is indicated by the q-deformation parameters of the phase space, the reference and controlled subsystems, including when using asymptotic approximations in forecasting methods using neural-network algorithms and deep-learning algorithms.

卫星监测时间序列的熵函数与信息差

摘要对美国戈达德航天飞行中心数据库提供的行星际磁场状态卫星监测时间序列信息进行了分析。在分析方法库中，主要关注的是在缩放基于2001-2022时间序列创建的时间样本时对非扩展特性的控制。给出了在考虑的实现系综中行星际磁场分量的概率分布函数的模态重建。给出了Shannon-Boltzmann-Gibbs、Tsallis和rsamnyi熵测度的动力学重建结果。在非扩展近似下，研究了相空间的q-变形对系统随机状态的影响。本文首次研究了行星际磁场值实现系综的信息差异动力学和熵测度动力学。需要通过相空间、参考和控制子系统的q-变形参数来表示，包括在使用神经网络算法和深度学习算法的预测方法中使用渐近逼近时。
