A mutually exciting latent space Hawkes process model for continuous-time networks

UAI 2022poster

Networks and temporal point processes serve as fundamental building blocks for modeling complex dynamic relational data in various domains. We propose the latent space Hawkes (LSH) model, a novel generative model for continuous-time networks of relational events, using a latent space representation…

The Multivariate Community Hawkes Model for Dependent Relational Events in Continuous-time Networks

ICML 2022spotlight

The stochastic block model (SBM) is one of the most widely used generative models for network data. Many continuous-time dynamic network models are built upon the same assumption as the SBM: edges or events between all pairs of nodes are conditionally independent given the block or community members…

CHIP: A Hawkes Process Model for Continuous-time Networks with Scalable and Consistent Estimation

NeurIPS 2020poster

In many application settings involving networks, such as messages between users of an on-line social network or transactions between traders in financial markets, the observed data consist of timestamped relational events, which form a continuous-time network. We propose the Community Hawkes Indepen…
