Hawkes过程被广泛用于模拟事件级联。然而,内容和跨领域的信息,这也是在建模工具通常被忽视。在本文中,我们提出了一种新的模型称为传输混合最小二乘霍克斯(trHLSH),结合霍克斯过程的内容和跨域信息。我们还提出了有效的学习算法的模型。在合成数据集和真实数据集上的测试结果表明,该模型能够从时间、内容和跨域信息中联合学习知识,在网络恢复和预测方面具有更好的性能。
Hawkes processes are widely used for modeling event cascades. However, content and cross-domain information which is also instrumental in modeling is usually neglected. In this paper, we propose a novel model called transfer Hybrid Least Square for Hawkes (trHLSH) that incorporates Hawkes processes with content and cross-domain information. We also present the effective learning algorithm for the model. Evaluation on both synthetic and real-world datasets demonstrates that the proposed model can jointly learn knowledge from temporal, content and cross-domain information, and has better performance in terms of network recovery and prediction.
