Modeling correlated human dynamics
摘要：
我们实证研究的活动模式的个人博客张贴，并发现显着的记忆效应。记忆系数先以幂律衰减，然后变成指数形式。此外，事件间的时间分布显示出重尾的性质与幂律指数依赖于活动。我们的研究结果挑战了优先队列模型，不能再现记忆效应或活动依赖的分布。我们认为还有另一种由个人兴趣驱动的人类活动模式，其特征是强烈的记忆效应。因此，我们提出了一个简单的基于时间偏好的模型，它可以很好地再现重尾性质和强记忆效应。这项工作有助于理解人类行为的时间性和可预测性。
英文摘要：
We empirically study the activity patterns of individual blog-posting and find significant memory effects. The memory coefficient first decays in a power law and then turns to an exponential form. Moreover, the inter-event time distribution displays a heavy-tailed nature with power-law exponent dependent on the activity. Our findings challenge the priority-queue model that can not reproduce the memory effects or the activity-dependent distributions. We think there is another kind of human activity patterns driven by personal interests and characterized by strong memory effects. Accordingly, we propose a simple model based on temporal preference, which can well reproduce both the heavy-tailed nature and the strong memory effects. This work helps in understanding both the temporal regularities and the predictability of human behaviors.
