Abstract

本发明属于无线通信技术领域,公开了一种基于AC‑GAN和动态概率调度的可靠联邦学习方法及系统,可以抵御标签噪声、非独立同分布数据和中毒攻击对全局模型性能的消极影响,包括两个阶段:数据预处理阶段,服务器在小基准数据集上训练一个AC‑GAN模型并部署在用户端,用户借助AC‑GAN模型实施数据清洗和数据增强,从而实现噪声标签矫正同时缓解非独立同分布数据的影响;攻击检测阶段,参数服务器构建用户选择概率模型,基于动态概率调度策略过滤恶意用户。为防止用户模型信息泄露和半诚实的服务器推测用户信息,利用CKKS同态加密方案对模型参数进行加密,并采用双服务器架构。本发明克服了标签噪声、非独立同分布数据和中毒攻击对模型性能的影响。
