The embedding network is used to\r\nrepresent clients in a latent descriptor space in a way that reflects their similarity\r\nto each other. The hypernetwork takes as input such descriptors and outputs the\r\nparameters of fully personalized client models. In combination, both networks\r\nconstitute a learning algorithm that achieves state-of-the-art performance in several\r\npersonalized federated learning benchmarks","lang":"eng"}],"file":[{"file_name":"2024_ICLR_Scott.pdf","checksum":"81b7ea2e667adaf9c7a7b6b376b1f251","content_type":"application/pdf","file_size":1029219,"relation":"main_file","date_created":"2024-08-12T07:38:06Z","file_id":"17415","date_updated":"2024-08-12T07:38:06Z","success":1,"creator":"dernst","access_level":"open_access"}],"date_published":"2024-03-07T00:00:00Z","oa_version":"Published Version","year":"2024","ddc":["000"],"status":"public","day":"07","publication":"12th International Conference on Learning Representations","date_updated":"2024-08-12T08:26:35Z","corr_author":"1","publisher":"OpenReview","has_accepted_license":"1","conference":{"end_date":"2024-03-07","start_date":"2024-03-07","location":"Vienna, Austria","name":"ICLR: International Conference on Learning Representations"},"scopus_import":"1","acknowledged_ssus":[{"_id":"ScienComp"}]}
