论文摘要
出现的现象是系统的微观动力学有助于发展非平淡无奇的更高规模的发展,已成为现代科学中的基本概念,将类似物理,生物学,经济学和生态学等多样化的领域捆绑在一起。尽管它显然是普遍性和引人注目的兴趣,但历史上的研究人员仍在努力提供对跨领域适用的严格,正式的形式定义。使用信息理论和网络科学的最新理论工作以形式化国家转变网络中的出现(因果关系)为前进提供了一种有希望的方向,但是这种新框架与其他熟悉的系统动态之间的关系尚不清楚。在这项研究中,我们将因果出现分析应用于两个良好描述的动力学系统:88个独特的基本细胞自动机和连续的Rossler System在周期性,关键和混乱的方案中。我们发现出现及其组成部分(确定性,堕落和有效性)在不同的动力学制度中以有时出乎意料的方式差异很大。我们得出的结论是,因果出现框架为许多领域的理论家和自然科学家提供了丰富的新研究领域。
Emergence, the phenomena where a system's micro-scale dynamics facilitate the development of non-trivial, informative higher scales, has become a foundational concept in modern sciences, tying together fields as diverse as physics, biology, economics, and ecology. Despite it's apparent universality and the considerable interest, historically researchers have struggled to provide a rigorous, formal definition of emergence that is applicable across fields. Recent theoretical work using information theory and network science to formalize emergence in state-transition networks (causal emergence) has provided a promising way forward, however the relationship between this new framework and other well-studied system dynamics is unknown. In this study, we apply causal emergence analysis to two well-described dynamical systems: the 88 unique elementary cellular automata and the continuous Rossler system in periodic, critical, and chaotic regimes. We find that emergence, as well as its component elements (determinism, degeneracy, and effectiveness) vary dramatically in different dynamical regimes in sometimes unexpected ways. We conclude that the causal emergence framework provides a rich new area of research to explore both to theoreticians and natural scientists in many fields.
