Federated Semi-supervised Learning for Medical Image Segmentation with intra-client and inter-client Consistency

no code implementations19 Mar 2024 Yubin Zheng, Peng Tang, Tianjie Ju, Weidong Qiu, Bo Yan

The intra-client and inter-client consistency learning are introduced to smooth predictions at the data level and avoid confirmation bias of local models.

Feature Norm Regularized Federated Learning: Transforming Skewed Distributions into Global Insights

1 code implementation12 Dec 2023 Ke Hu, Weidong Qiu, Peng Tang

Our comprehensive analysis reveals that FNR-FL not only accelerates convergence but also significantly surpasses other contemporary federated learning algorithms in test accuracy, particularly under feature distribution skew scenarios.

Support or Refute: Analyzing the Stance of Evidence to Detect Out-of-Context Mis- and Disinformation

no code implementations3 Nov 2023 Xin Yuan, Jie Guo, Weidong Qiu, Zheng Huang, Shujun Li

Mis- and disinformation online have become a major societal problem as major sources of online harms of different kinds.

SE#PCFG: Semantically Enhanced PCFG for Password Analysis and Cracking

no code implementations12 Jun 2023 Yangde Wang, Weidong Qiu, Weicheng Zhang, Hao Tian, Shujun Li

Furthermore, based on SE#PCFG and a new systematic smoothing method, we proposed the Semantically Enhanced Password Cracking Architecture (SEPCA).

Scale Invariant Domain Generalization Image Recapture Detection

no code implementations7 Oct 2021 Jinian Luo, Jie Guo, Weidong Qiu, Zheng Huang, Hong Hui

However, most of them ignored the domain generalization scenario and scale variances, with an inferior performance on domain shift situations, and normally were exacerbated by intra-domain and inter-domain scale variances.

DAFAR: Defending against Adversaries by Feedback-Autoencoder Reconstruction

no code implementations11 Mar 2021 Haowen Liu, Ping Yi, Hsiao-Ying Lin, Jie Shi, Weidong Qiu

We propose DAFAR, a feedback framework that allows deep learning models to detect/purify adversarial examples in high effectiveness and universality, with low area and time overhead.

PatternMonitor: a whole pipeline with a much higher level of automation for guessing Android lock pattern based on videos

no code implementations2 Feb 2021 Yangde Wang, Weidong Qiu, Yuming Xie, Yan Zha

To the best of our knowledge, our work is the first attack system to generate candidate patterns by only relying on hand movement instead of accurate fingertips capture.
