PyHawkes implements a variety of Bayesian inference algorithms for discovering latent network structure given point process observations. Suppose you observe timestamps of Twitter messages, but you don't get to see how those users are connected to one another. You might infer that there is an uno...
Hawkes-Process-Toolkit是一个用于模拟和分析霍克斯过程(Hawkes processes)的工具包。霍克斯过程是一种用于建模事件发生的随机过程,其特点是事件的发生率受到之前发生事件的影响。 Hawkes-Process-Toolkit提供了一套丰富的功能,使用户能够灵活地构建、仿真和分析霍克斯过程。工具包支持多种类型的霍克斯过程模型,包括指数核(...

By introducing the Deep Hawkes process to the high-frequency market making strategy, we allow a feedback loop to be created between order arrival and the state of the limit order book, together with self- and cross-excitation effects. Our high-frequency market making strategy accounts for the ...

Hence, the intensity function of the Hawkes process has two components, namely the baseline intensity which triggers arrivals not due to excitation and the excitation part. In Hawkes (1971), where the process was originally introduced, it is assumed that the jumps are positive. The analysis of...
