PlugAT: A Plug and Play Module to Defend against Textual Adversarial Attack

no code implementations COLING 2022 Rui Zheng, Rong Bao, Qin Liu, Tao Gui, Qi Zhang, Xuanjing Huang, Rui Xie, Wei Wu

To reduce the potential side effects of using defense modules, we further propose a novel forgetting restricted adversarial training, which filters out bad adversarial examples that impair the performance of original ones.

Efficient Adversarial Training with Robust Early-Bird Tickets

1 code implementation14 Nov 2022 Zhiheng Xi, Rui Zheng, Tao Gui, Qi Zhang, Xuanjing Huang

Adversarial training is one of the most powerful methods to improve the robustness of pre-trained language models (PLMs).

Robust Lottery Tickets for Pre-trained Language Models

1 code implementation ACL 2022 Rui Zheng, Rong Bao, Yuhao Zhou, Di Liang, Sirui Wang, Wei Wu, Tao Gui, Qi Zhang, Xuanjing Huang

Recent works on Lottery Ticket Hypothesis have shown that pre-trained language models (PLMs) contain smaller matching subnetworks(winning tickets) which are capable of reaching accuracy comparable to the original models.

TriangleNet: Edge Prior Augmented Network for Semantic Segmentation through Cross-Task Consistency

no code implementations11 Oct 2022 Dan Zhang, Rui Zheng, Luosang Gadeng, Pei Yang

Semantic segmentation is a classic computer vision problem dedicated to labeling each pixel with its corresponding category.

Automatic spinal curvature measurement on ultrasound spine images using Faster R-CNN

no code implementations17 Apr 2022 Zhichao Liu, Liyue Qian, Wenke Jing, Desen Zhou, Xuming He, Edmond Lou, Rui Zheng

The framework consisted of two closely linked modules: 1) the lamina detector for identifying and locating each lamina pairs on ultrasound coronal images, and 2) the spinal curvature estimator for calculating the scoliotic angles based on the chain of detected lamina.

Decorrelate Irrelevant, Purify Relevant: Overcome Textual Spurious Correlations from a Feature Perspective

2 code implementations COLING 2022 Shihan Dou, Rui Zheng, Ting Wu, Songyang Gao, Junjie Shan, Qi Zhang, Yueming Wu, Xuanjing Huang

Most of the existing debiasing methods often identify and weaken these samples with biased features (i. e., superficial surface features that cause such spurious correlations).

Automatic segmentation of vertebral features on ultrasound spine images using Stacked Hourglass Network

no code implementations9 May 2021 Hong-Ye Zeng, Song-Han Ge, Yu-Chong Gao, De-Sen Zhou, Kang Zhou, Xu-Ming He, Edmond Lou, Rui Zheng

Methods: The network was trained to detect vertebral SP and laminae as five landmarks on 1200 ultrasound transverse images and validated on 100 images.

Cardea: Context-Aware Visual Privacy Protection from Pervasive Cameras

no code implementations4 Oct 2016 Jiayu Shu, Rui Zheng, Pan Hui

The growing popularity of mobile and wearable devices with built-in cameras, the bright prospect of camera related applications such as augmented reality and life-logging system, the increased ease of taking and sharing photos, and advances in computer vision techniques have greatly facilitated people's lives in many aspects, but have also inevitably raised people's concerns about visual privacy at the same time.
