SIBO: A Simple Booster for Parameter-Efficient Fine-Tuning

no code implementations19 Feb 2024 Zhihao Wen, Jie Zhang, Yuan Fang

Fine-tuning all parameters of large language models (LLMs) necessitates substantial computational power and extended time.

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.

Prompt Tuning on Graph-augmented Low-resource Text Classification

1 code implementation15 Jul 2023 Zhihao Wen, Yuan Fang

During pre-training, we propose three graph interaction-based contrastive strategies to jointly pre-train a graph-text model; during downstream classification, we explore handcrafted discrete prompts and continuous prompt tuning for the jointly pre-trained model to achieve zero- and few-shot classification, respectively.

Meta-Inductive Node Classification across Graphs

no code implementations14 May 2021 Zhihao Wen, Yuan Fang, Zemin Liu

That is, MI-GNN does not directly learn an inductive model; it learns the general knowledge of how to train a model for semi-supervised node classification on new graphs.
