WebAbstract Graph anomaly detection has attracted a lot of interest recently. Despite their successes, existing detectors have at least two of the three weaknesses: (a) high computational cost which limits them to small-scale networks only; (b) existing treatment of subgraphs produces suboptimal detection accuracy; and (c) unable to provide an … WebTo further enhance the question representation, we supplement the supervised prediction task of KT with an auxiliary self-supervised task, i.e., we additionally generate an augmented view with adaptive data augmentation to implement contrastive learning and exploit the unobserved relations among questions.
Webhypergraphs. A hypergraph contrastive learning method, named AEHCL, is proposed to fully capture abnormal event patterns. AEHCL designs the intra-event and inter-event contrastive modules to exploit self-supervised AHIN information. The intra-event contrastive module captures the pair-wise and multivariate interaction anomalies within WebInformation Retrieval Research Topic ideas for MS, or Ph.D. Degree.

Webhypergraph. Note that not all hypergraphs are down-hypergraphs of a DAG, but they are easily recognized: We say that a hypergraph has the unique element property if each hyperedge contains a vertex not contained in any other hyperedge. We can observe that a hypergraph H is a down-hypergraph of some DAG iff H has the unique element … WebHypergraph Structure Learning for Hypergraph Neural Networks Derun Cai 1,2, Moxian Song , Chenxi Sun1,2, Baofeng Zhang1,2, Shenda Hong3,4∗ and Hongyan Li1,2∗ 1Key Laboratory of Machine Perception (Ministry of Education), Peking University, Beijing, China. 2School of Electronics Engineering and Computer Science, Peking University, Beijing, …
