🤖 AI Summary
Real-world networks exhibit higher-order relationships characterized by both short-term structural dependencies and long-term periodic recurrence—properties that existing methods struggle to jointly model. To address this, we propose LINCOLN, the first framework unifying bidirectional short-range interaction effects (O1) and periodic long-range reoccurrence (O2) in higher-order relational dynamics. LINCOLN innovatively integrates dual-interaction hyperedge encoding, periodic temporal injection, and intermediate node representation learning to jointly capture local structural constraints and global temporal regularities. Evaluated on dynamic hyperedge prediction, LINCOLN consistently outperforms nine state-of-the-art baselines across multiple benchmarks, demonstrating superior accuracy in modeling complex, time-varying higher-order network evolution.
📝 Abstract
Real-world networks have high-order relationships among objects and they evolve over time. To capture such dynamics, many works have been studied in a range of fields. Via an in-depth preliminary analysis, we observe two important characteristics of high-order dynamics in real-world networks: high-order relations tend to (O1) have a structural and temporal influence on other relations in a short term and (O2) periodically re-appear in a long term. In this paper, we propose LINCOLN, a method for Learning hIgh-order dyNamiCs Of reaL-world Networks, that employs (1) bi-interactional hyperedge encoding for short-term patterns, (2) periodic time injection and (3) intermediate node representation for long-term patterns. Via extensive experiments, we show that LINCOLN outperforms nine state-of-the-art methods in the dynamic hyperedge prediction task.
