突发人体动力学中不确定性的优化减少
Optimized reduction of uncertainty in bursty human dynamics
摘要：
人的动力学是已知的，是不均匀的和突发的，但在突发动力学的人的因素的作用的详细了解仍然缺乏。为了研究他们的角色，我们设计了一个基于代理的模型，在不确定的情况下，代理试图通过与信息提供者进行通信，同时等待响应时间来减少不确定性。在这里，等待时间可以被视为成本。我们表明，在不确定性下的等待时间的最佳选择引起的突发动态，其特征在于重尾分布的最佳等待时间。我们发现，在所有情况下，通信的效率是相关的最佳等待时间分布的缩放行为。另一方面，根据不确定性和效率的程度，成本在某些情况下是无关紧要的。
英文摘要：
Human dynamics is known to be inhomogeneous and bursty but the detailed understanding of the role of human factors in bursty dynamics is still lacking. In order to investigate their role we devise an agent-based model, where an agent in an uncertain situation tries to reduce the uncertainty by communicating with information providers while having to wait time for responses. Here the waiting time can be considered as cost. We show that the optimal choice of the waiting time under uncertainty gives rise to the bursty dynamics, characterized by the heavy-tailed distribution of optimal waiting time. We find that in all cases the efficiency for communication is relevant to the scaling behavior of the optimal waiting time distribution. On the other hand the cost turns out in some cases to be irrelevant depending on the degree of uncertainty and efficiency.
