However, in real-world scenarios, open-set recognition challenges frequently arise, where the accuracy of existing methods tends to be low. To address this issue, this paper proposes a versatile classification framework that integrates federated learning and meta-learning to tackle open-set recognition in federated environments. In the proposed methodology, federated meta-learning is first employed to train a global model with strong generalization capabilities across different clients, while preserving data privacy. Then, each local client extracts features and applies a relational network-based classifier to perform classification, obtaining the final prediction results. The local models are updated accordingly, and a coefficient-based aggregation algorithm is designed to update the global model, considering both the aggregation coefficients and classification accuracy. Finally, the server distributes the updated global model back to the clients, who update their local models and proceed to the next training round. To validate the effectiveness of the proposed approach, open-set recognition experiments are conducted on the MNIST, CIFAR-100, and Omniglot datasets. Experimental results demonstrate that the proposed method not only ensures local data privacy but also achieves higher accuracy compared to baseline algorithms such as FedAvg.<\/jats:p>","DOI":"10.15837\/ijccc.2026.3.7033","type":"journal-article","created":{"date-parts":[[2026,5,26]],"date-time":"2026-05-26T11:13:27Z","timestamp":1779794007000},"source":"Crossref","is-referenced-by-count":0,"title":["Federated Meta-Learning for Open Set Identification with Privacy Preservation"],"prefix":"10.15837","volume":"21","author":[{"given":"Lang","family":"Wu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"6528","published-online":{"date-parts":[[2026,5,26]]},"container-title":["INTERNATIONAL JOURNAL OF COMPUTERS  COMMUNICATIONS &amp; CONTROL"],"original-title":[],"deposited":{"date-parts":[[2026,5,26]],"date-time":"2026-05-26T11:13:27Z","timestamp":1779794007000},"score":1,"resource":{"primary":{"URL":"https:\/\/univagora.ro\/jour\/index.php\/ijccc\/article\/view\/7033"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2026,5,26]]},"references-count":0,"journal-issue":{"issue":"3","published-online":{"date-parts":[[2026,5,26]]}},"URL":"https:\/\/doi.org\/10.15837\/ijccc.2026.3.7033","relation":{},"ISSN":["1841-9844","1841-9836"],"issn-type":[{"value":"1841-9844","type":"electronic"},{"value":"1841-9836","type":"print"}],"subject":[],"published":{"date-parts":[[2026,5,26]]}}}
