A More Stable Accelerated Gradient Method Inspired by Continuous-Time Perspective

no code implementations9 Dec 2021 Yasong Feng, Weiguo Gao

Experiments of matrix completion and handwriting digit recognition demonstrate that the stability of our new method is better.

SOFT: Softmax-free Transformer with Linear Complexity

no code implementations NeurIPS 2021 Jiachen Lu, Jinghan Yao, Junge Zhang, Xiatian Zhu, Hang Xu, Weiguo Gao, Chunjing Xu, Tao Xiang, Li Zhang

Crucially, with a linear complexity, much longer token sequences are permitted in SOFT, resulting in superior trade-off between accuracy and complexity.

A Diversity-Enhanced and Constraints-Relaxed Augmentation for Low-Resource Classification

no code implementations24 Sep 2021 Guang Liu, Hailong Huang, Yuzhao Mao, Weiguo Gao, Xuan Li, Jianping Shen

Previous studies mostly use a fine-tuned Language Model (LM) to strengthen the constraints but ignore the fact that the potential of diversity could improve the effectiveness of generated data.

Adversarial Mixing Policy for Relaxing Locally Linear Constraints in Mixup

1 code implementation EMNLP 2021 Guang Liu, Yuzhao Mao, Hailong Huang, Weiguo Gao, Xuan Li

To address these issues, we propose the Adversarial Mixing Policy (AMP), organized in a min-max-rand formulation, to relax the Locally Linear Constraints in Mixup.

A new accelerated gradient method inspired by continuous-time perspective

no code implementations1 Jan 2021 Yasong Feng, Weiguo Gao

To give more insight about the acceleration phenomenon, an ordinary differential equation was obtained from Nesterov's accelerated method by taking step sizes approaching zero, and the relationship between Nesterov's method and the differential equation is still of research interest.
