摘要翻译：
行为启动是领导的一种形式，是社会组织的一个重要方面，它影响着人类社会和其他社会性动物的群体形成、动态和决策过程。在这项工作中，我们形式化了“协调发起者推理问题”，并提出了一个简单而强大的框架，用于提取协调活动的周期，并确定发起协调的个体，仅基于这些周期内个体的活动。在给定任意个体时间序列的情况下，所提出的方法可以自动地（1）识别协同群体活动的时间，(2)确定这些活动的发起者的身份，(3)对群体协调发生的可能机制进行分类，所有这些都是新的计算任务。我们在模拟和真实世界的数据上演示了我们的框架：动物轨迹跟踪以及股票市场数据。我们的方法与现有的全局领导力推理方法相比具有竞争力，但为局部领导力和协调机制分类提供了第一个方法。我们的结果与真实的生物数据一致，该框架在金融数据中发现了许多已知的事件，这些事件在纳斯达克指数中没有得到反映。我们的方法很容易推广到任何来自交互实体的协调时间序列数据。

分类信息：

一级分类：Computer Science        计算机科学
二级分类：Social and Information Networks        社会和信息网络
分类描述：Covers the design, analysis, and modeling of social and information networks, including their applications for on-line information access, communication, and interaction, and their roles as datasets in the exploration of questions in these and other domains, including connections to the social and biological sciences. Analysis and modeling of such networks includes topics in ACM Subject classes F.2, G.2, G.3, H.2, and I.2; applications in computing include topics in H.3, H.4, and H.5; and applications at the interface of computing and other disciplines include topics in J.1--J.7. Papers on computer communication systems and network protocols (e.g. TCP/IP) are generally a closer fit to the Networking and Internet Architecture (cs.NI) category.

英文摘要：
  Behavior initiation is a form of leadership and is an important aspect of social organization that affects the processes of group formation, dynamics, and decision-making in human societies and other social animal species. In this work, we formalize the "Coordination Initiator Inference Problem" and propose a simple yet powerful framework for extracting periods of coordinated activity and determining individuals who initiated this coordination, based solely on the activity of individuals within a group during those periods. The proposed approach, given arbitrary individual time series, automatically (1) identifies times of coordinated group activity, (2) determines the identities of initiators of those activities, and (3) classifies the likely mechanism by which the group coordination occurred, all of which are novel computational tasks. We demonstrate our framework on both simulated and real-world data: trajectories tracking of animals as well as stock market data. Our method is competitive with existing global leadership inference methods but provides the first approaches for local leadership and coordination mechanism classification. Our results are consistent with ground-truthed biological data and the framework finds many known events in financial data which are not otherwise reflected in the aggregate NASDAQ index. Our method is easily generalizable to any coordinated time-series data from interacting entities.
