Complete-Tree Space Favors Data-Efficient Link Prediction

Chi Gao, Lukai Li, Yancheng Zhou, Shangqi Guo

ICML 2025poster

Link prediction is a fundamental problem for network-structured data. However, the prevalent research paradigm tends to assume abundant observed links, overlooking more challenging scenarios with a scarcity of observed links, which results in insufficient sample sizes. In real-world networks, hierar…

Noether Embedding: Efficient Learning of Temporal Regularities

Chi Gao, Zidong Zhou, Luping Shi

NeurIPS 2023poster

Learning to detect and encode temporal regularities (TRs) in events is a prerequisite for human-like intelligence. These regularities should be formed from limited event samples and stored as easily retrievable representations. Existing event embeddings, however, cannot effectively decode TR validit…
