Enhancing Learning with Label Differential Privacy by Vector Approximation

no code implementations24 May 2024 Puning Zhao, Rongfei Fan, Huiwen Wu, Qingming Li, Jiafei Wu, Zhe Liu

Label differential privacy (DP) is a framework that protects the privacy of labels in training datasets, while the feature vectors are public.

CG-FedLLM: How to Compress Gradients in Federated Fune-tuning for Large Language Models

no code implementations22 May 2024 Huiwen Wu, Xiaohan Li, Deyi Zhang, Xiaogang Xu, Jiafei Wu, Puning Zhao, Zhe Liu

The success of current Large-Language Models (LLMs) hinges on extensive training data that is collected and stored centrally, called Centralized Learning (CL).

A Huber Loss Minimization Approach to Mean Estimation under User-level Differential Privacy

no code implementations22 May 2024 Puning Zhao, Lifeng Lai, Li Shen, Qingming Li, Jiafei Wu, Zhe Liu

We provide a theoretical analysis of our approach, which gives the noise strength needed for privacy protection, as well as the bound of mean squared error.

Learn Suspected Anomalies from Event Prompts for Video Anomaly Detection

no code implementations2 Mar 2024 Chenchen Tao, Chong Wang, Yuexian Zou, Xiaohao Peng, Jiafei Wu, Jiangbo Qian

Most models for weakly supervised video anomaly detection (WS-VAD) rely on multiple instance learning, aiming to distinguish normal and abnormal snippets without specifying the type of anomaly.

Dynamic Relevance Learning for Few-Shot Object Detection

1 code implementation4 Aug 2021 Weijie Liu, Chong Wang, Haohe Li, Shenghao Yu, Jiafei Wu

By adjusting the prediction distribution of the base detector using the output of this GCN, the proposed model serves as a hard auxiliary classification task, which guides the detector to improve the class representation implicitly.
