However, previous work often overlooks the unique contributions of labels to the target variables in multi-label settings, focusing instead on prioritizing feature variables. Moreover, existing methods typically rely on traditional Markov Blanket (MB) discovery to construct an initial MB, which often fails to explore the most valuable form of spouse variables to feature selection in multi-label scenarios, leading to significant computational overhead due to redundant Conditional Independence (CI) tests required for spouse search. To address these challenges, we propose the Multi-label Causal Feature Selection Method with Optimal Spouses Discovery, MCF-Spouse, which leverages mutual information to quantify the contributions of both labels and features, ensuring the retention of the most informative variables in multi-label settings. Moreover, we systematically analyzes all potential forms of spouse variables to identify the optimal spouse case, significantly reducing the spouse search space and alleviating the time overhead associated with CI tests. Experiments conducted on diverse real-world datasets demonstrate that MCF-Spouse consistently outperforms state-of-the-art methods across multiple metrics, offering a scalable and interpretable solution for multi-label causal feature selection.<\/jats:p>","DOI":"10.24963\/ijcai.2025\/658","type":"proceedings-article","created":{"date-parts":[[2025,9,19]],"date-time":"2025-09-19T08:10:40Z","timestamp":1758269440000},"page":"5914-5922","source":"Crossref","is-referenced-by-count":0,"title":["MCF-Spouse: A Multi-Label Causal Feature Selection Method with Optimal Spouses Discovery"],"prefix":"10.24963","author":[{"given":"Lin","family":"Ma","sequence":"first","affiliation":[{"name":"Jilin University"}]},{"given":"Liang","family":"Hu","sequence":"additional","affiliation":[{"name":"Jilin University"}]},{"given":"Qiang","family":"Huang","sequence":"additional","affiliation":[{"name":"Mohamed Bin Zayed University of Artificial Intelligence"}]},{"given":"Pingting","family":"Hao","sequence":"additional","affiliation":[{"name":"Northeast Normal University"}]},{"given":"Juncheng","family":"Hu","sequence":"additional","affiliation":[{"name":"Jilin University"}]}],"member":"10584","event":{"number":"34","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"acronym":"IJCAI-2025","name":"Thirty-Fourth International Joint Conference on Artificial Intelligence {IJCAI-25}","start":{"date-parts":[[2025,8,16]]},"theme":"Artificial Intelligence","location":"Montreal, Canada","end":{"date-parts":[[2025,8,22]]}},"container-title":["Proceedings of the Thirty-Fourth International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2025,9,23]],"date-time":"2025-09-23T11:34:45Z","timestamp":1758627285000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2025\/658"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2025,9]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2025\/658","relation":{},"subject":[],"published":{"date-parts":[[2025,9]]}}}
