Topology-aware Graph Diffusion Model with Persistent Homology

NeurIPS 2025poster

Generating realistic graphs faces challenges in estimating accurate distribution of graphs in an embedding space while preserving structural characteristics. However, existing graph generation methods primarily focus on approximating the joint distribution of nodes and edges, often overlooking topol…

Decoupled Marked Temporal Point Process using Neural Ordinary Differential Equations

ICLR 2024poster

A Marked Temporal Point Process (MTPP) is a stochastic process whose realization is a set of event-time data. MTPP is often used to understand complex dynamics of asynchronous temporal events such as money transaction, social media, healthcare, etc. Recent studies have utilized deep neural networks…
