Neural temporal point processes(TPPs) have shown promise for modeling
continuous-time event sequences. However, capturing the interactions between
events is challenging yet critical for performing inference tasks like
forecasting on event sequence data. Existing TPP models have focused on
parameterizing the conditional distribution of future events but struggle to
model event interactions. In this paper, we propose a novel approach that
leverages Neural Relational Inference (NRI) to learn a relation graph that
infers interactions while simultaneously learning the dynamics patterns from
observational data. Our approach, the Contrastive Relational Inference-based
Hawkes Process (CRIHP), reasons about event interactions under a variational
inference framework. It utilizes intensity-based learning to search for
prototype paths to contrast relationship constraints. Extensive experiments on
three real-world datasets demonstrate the effectiveness of our model in
capturing event interactions for event sequence modeling tasks.

我们提出了一种新颖的方法，利用神经关系推断来学习关系图，以从观测数据中推断事件相互作用，并同时学习动态模式。我们的方法在变分推断框架下对事件相互作用进行推理，并利用基于强度的学习来搜索原型路径以对比关系约束。在三个真实世界数据集上的大量实验证明了我们的模型在事件序列建模任务中捕捉事件相互作用的有效性。
