Domain Adaptive Graph Classification

no code implementations21 Dec 2023 Siyang Luo, Ziyi Jiang, Zhenghan Chen, Xiaoxuan Liang

Moreover, our approach incorporates adaptive perturbations into the dual branches, which align the source and target distribution to address domain discrepancies.

Dynamic Spiking Graph Neural Networks

no code implementations15 Dec 2023 Nan Yin, Mengzhu Wang, Zhenghan Chen, Giulia De Masi, Bin Gu, Huan Xiong

Current work often uses SNNs instead of Recurrent Neural Networks (RNNs) by using binary features instead of continuous ones for efficient training, which would overlooks graph structure information and leads to the loss of details during propagation.

Just-in-Time Security Patch Detection -- LLM At the Rescue for Data Augmentation

no code implementations2 Dec 2023 Xunzhu Tang, Zhenghan Chen, Kisub Kim, Haoye Tian, Saad Ezzini, Jacques Klein

To address this pressing issue, we introduce a novel security patch detection system, LLMDA, which capitalizes on Large Language Models (LLMs) and code-text alignment methodologies for patch review, data enhancement, and feature combination.
