Federated distillation method based on feature projection and adaptive enhancement
为了解决现有联邦蒸馏方法难以处理异构模型间表征空间不一致与特征分布不均的问题,提出一种基于特征投影与自适应增强的联邦蒸馏方法,实现了跨异构客户端模型的知识高效融合.该方法在服务器端通过蒸馏方式整合客户端输出,在客户端设计轻量化多出口分支,将异构模型的中间特征投影到对齐的logits空间,以突破异构蒸馏中的特征对齐瓶颈.实验结果表明,该方法在标准数据集上取得良好效果,减少了通信轮次和数据传输量,同时增强了系统在异构环境下的鲁棒性,为联邦异构知识融合提供了一种有效的新方案.
To address the problem that existing federated distillation methods struggle to handle inconsistent representa-tion spaces and uneven feature distributions across heterogeneous models,a federated distillation method based on fea-ture projection and adaptive enhancement was proposed,achieving efficient knowledge fusion across heterogeneous cli-ent models.On the server side,client outputs were integrated via distillation.On the client side,lightweight multi-exit branches were employed to project intermediate features into an aligned logits space to overcome feature alignment bottlenecks.Promising performance was demonstrated on benchmark datasets,with reduced communication rounds and data transmission as well as enhanced system robustness,thus providing an effective new solution for heterogeneous model knowledge fusion in federated learning.
