Self-Supervised Prime-Dual Networks for Few-Shot Image Classification

no code implementations29 Sep 2021 Wenming Cao, Qifan Liu, Guang Liu, Zhihai He

We construct a prime-dual network structure for few-shot learning which establishes a commutative relationship between the support set and the query set, as well as a new self- supervision constraint for highly effective few-shot learning.

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.

Research on multi-dimensional end-to-end phrase recognition algorithm based on background knowledge

no code implementations8 Jul 2020 Zheng Li, Gang Tu, Guang Liu, Zhi-Qiang Zhan, Yi-Jian Liu

The algorithm can not only introduce background knowledge, recognize all kinds of nested phrases in sentences, but also recognize the dependency between phrases.

Research on Annotation Rules and Recognition Algorithm Based on Phrase Window

no code implementations7 Jul 2020 Guang Liu, Gang Tu, Zheng Li, Yi-Jian Liu

At present, most Natural Language Processing technology is based on the results of Word Segmentation for Dependency Parsing, which mainly uses an end-to-end method based on supervised learning.
