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).

Integrated routing for a vehicle-robot pickup and delivery system with time constraints

no code implementations9 Feb 2022 Yongjian Li, Yan Chen, Gaicong Guo, Huiwen Wu, Zhao Yuan

This paper considers an unmanned vehicle-robot pickup and delivery system, in which a self-driving vehicle carrying multiple unmanned robots in the form of the mother ship travels from a depot to a number of stations distributed in a neighborhood to perform multiple pickup and delivery services.

A Theoretical Perspective on Differentially Private Federated Multi-task Learning

no code implementations14 Nov 2020 Huiwen Wu, Cen Chen, Li Wang

In the era of big data, the need to expand the amount of data through data sharing to improve model performance has become increasingly compelling.
