VCR-Graphormer: A Mini-batch Graph Transformer via Virtual Connections

no code implementations24 Mar 2024 Dongqi Fu, Zhigang Hua, Yan Xie, Jin Fang, Si Zhang, Kaan Sancak, Hao Wu, Andrey Malevich, Jingrui He, Bo Long

Therefore, mini-batch training for graph transformers is a promising direction, but limited samples in each mini-batch can not support effective dense attention to encode informative representations.

MentorGNN: Deriving Curriculum for Pre-Training GNNs

1 code implementation21 Aug 2022 Dawei Zhou, Lecheng Zheng, Dongqi Fu, Jiawei Han, Jingrui He

To comprehend heterogeneous graph signals at different granularities, we propose a curriculum learning paradigm that automatically re-weighs graph signals in order to ensure a good generalization in the target domain.
