Voucher Abuse Detection with Prompt-based Fine-tuning on Graph Neural Networks

no code implementations19 Aug 2023 Zhihao Wen, Yuan Fang, Yihan Liu, Yang Guo, Shuji Hao

We design a novel graph prompting function to reformulate the downstream task into a similar template as the pretext task in pre-training, thereby narrowing the objective gap.

Balanced Distribution Adaptation for Transfer Learning

no code implementations2 Jul 2018 Jindong Wang, Yiqiang Chen, Shuji Hao, Wenjie Feng, Zhiqi Shen

To tackle the distribution adaptation problem, in this paper, we propose a novel transfer learning approach, named as Balanced Distribution \underline{A}daptation~(BDA), which can adaptively leverage the importance of the marginal and conditional distribution discrepancies, and several existing methods can be treated as special cases of BDA.
