Abstract:

Federated learning is a distributed machine learning framework that effectively addresses the data silo problem and is crucial for ensuring privacy protection for individuals and organizations. However, enhancing the efficiency of federated learning remains a pressing issue due to the unsatisfactory high cost of federated learning caused by the characteristics of this learning. Therefore, a comprehensive summary and investigation of current mainstream research on improving the efficiency of federated learning was provided. Firstly, the background of efficient federated learning, including its origins and core ideas, was reviewed, and the concepts as well as classification of federated learning were explained. Secondly, the efficiency challenges generated by federated learning were discussed and categorized into heterogeneous problems, personalized problems, and communication cost issues. Thirdly, on the above basis, detailed solutions to these efficiency problems were analyzed and discussed, and the research on efficiency of federated learning was categorized into two areas: model compression optimization methods and communication optimization methods, and investigated. Fourthly, by comparison analysis, the advantages and disadvantages of each federated learning method were summarized, and the challenges still exist in efficient federated learning were expounded. Finally, the future research directions in efficient federated learning field were given.

Key words: federated learning, deep learning, communication efficiency, privacy protection, machine learning

摘要:

联邦学习作为一个分布式机器学习框架,解决了数据孤岛问题,对个人及企业的隐私保护起到了重要作用。然而,由于联邦学习的特点,效率问题(尤其是高昂的成本)仍旧是目前急需解决的,这一现状仍不尽如人意。因此,全面调研并总结当前主流的关于联邦学习高效性的研究。首先,回顾高效联邦学习的背景,包括它的由来以及核心思想,并解释联邦学习的概念和分类;其次,论述基于联邦学习而产生的高效性问题,并将它们分为异构性问题、个性化问题和通信代价问题;再次,在此基础上详细分析并论述高效性问题的解决方案,并将高效联邦学习研究分为模型压缩优化方法以及通信优化方法这2个类别后进行调研;继次,通过对比分析,总结各联邦学习方法的优缺点,并阐述目前高效联邦学习中仍存在的挑战;最后,给出高效联邦学习领域未来的研究方向。
