Towards Multi-view Graph Anomaly Detection with Similarity-Guided Contrastive Clustering

no code implementations15 Sep 2024 Lecheng Zheng, John R. Birge, Yifang Zhang, Jingrui He

Theoretically, we show that the proposed similarity-guided loss is a variant of contrastive learning loss, and how it alleviates the issue of unreliable pseudo-labels with the connection to graph spectral clustering.

LAiW: A Chinese Legal Large Language Models Benchmark

1 code implementation9 Oct 2023 Yongfu Dai, Duanyu Feng, Jimin Huang, Haochen Jia, Qianqian Xie, Yifang Zhang, Weiguang Han, Wei Tian, Hao Wang

Through automated evaluation of current general and legal domain LLMs on our benchmark, we indicate that these LLMs may not align with the logic of legal practice.
