Publication number: 20240119307Abstract: The embodiments are directed towards providing personalized federated learning (PFL) models via sharable federated basis models. A model architecture and learning algorithm for PFL models is disclosed. The embodiments learn a set of basis models, which can be combined layer by layer to form a personalized model for each client using specifically learned combination coefficients. The set of basis models are shared with each client of a set of the clients. Thus, the set of basis models is common to each client of the set of clients. However, each client may generate a unique PFL based on their specifically learned combination coefficients. The unique combination of coefficients for each client may be encoded in a separate personalized vector for each of the clients.Type: ApplicationFiled: September 26, 2023Publication date: April 11, 2024Inventors: Hong-You Chen, Boqing Gong, Mingda Zhang, Hang Qi, Xuhui Jia, Li Zhang
