摘要
Currently, with the advancement of artificial intelligence research, artificial intelligence is being widely adopted, and the increasing demand in areas such as data governance has led to growing awareness and concern for privacy protection, this has promoted the popularity of the federated learning (FL) framework. However, existing FL frameworks struggle to address heterogeneous issues and personalized user needs. In response to these challenges, methods of personalized federated learning (PFL) are studied and prospects are proposed. Firstly, the FL framework is outlined and its limitations are identified, leading to the research motivation for PFL based on FL scenarios. Subsequently, the analysis of statistical heterogeneity, model heterogeneity, communication heterogeneity, and device heterogeneity in PFL is conducted, and feasible solutions are proposed. Then, personalized algorithms in PFL such as client selection and knowledge distillation are categorized, and their innovations and shortcomings are analyzed. Finally, future research directions for PFL are discussed. © 2024 Journal of Computer Engineering and Applications Beijing Co., Ltd.; Science Press. All rights reserved.
