Our convergence analysis and experiments prove this is a better way to improve convergence stability and rate in ZO-SGD.

Confounder Balancing in Adversarial Domain Adaptation for Pre-Trained Large Models Fine-Tuning

no code implementations • 24 Oct 2023 • Shuoran Jiang, Qingcai Chen, Yang Xiang, Youcheng Pan, XiangPing Wu

However, existing ADA methods fail to account for the confounder properly, which is the root cause of the source data distribution that differs from the target domains.

Multi-hop Graph Convolutional Network with High-order Chebyshev Approximation for Text Reasoning

1 code implementation • ACL 2021 • Shuoran Jiang, Qingcai Chen, Xin Liu, Baotian Hu, Lisai Zhang

In this study, we define the spectral graph convolutional network with the high-order dynamic Chebyshev approximation (HDGCN), which augments the multi-hop graph reasoning by fusing messages aggregated from direct and long-term dependencies into one convolutional layer.
