Flower を拡張し,非同期式・非中央集権型の連合学習に対応した実用的なフレームワークを設計する.Flower が採用している gRPC を用いて効率的な通信が実現でき,中央サーバにあたるものを配置せずに実機への拡張ができることが期待される.提案手法についての評価を行い,更新履歴を用いたモデル統合が有効であることを示した.統合と学習の順序については,条件設定に応じて優位となる順序が異なることを示した.","subitem_description_type":"Other"}]},"item_4_biblio_info_10":{"attribute_name":"書誌情報","attribute_value_mlt":[{"bibliographicPageEnd":"8","bibliographic_titles":[{"bibliographic_title":"研究報告インターネットと運用技術(IOT)"}],"bibliographicPageStart":"1","bibliographicIssueDates":{"bibliographicIssueDate":"2023-03-08","bibliographicIssueDateType":"Issued"},"bibliographicIssueNumber":"5","bibliographicVolumeNumber":"2023-IOT-60"}]},"relation_version_is_last":true,"weko_creator_id":"44499"},"updated":"2025-01-19T12:58:47.747104+00:00","created":"2025-01-19T01:24:27.835963+00:00","links":{},"id":224945}
