However, in practice, as data-gathering process cannot be fully controlled, sample selection bias often occurs, leading to spurious correlations between features and the class variable, which seriously deteriorates the performance of those existing methods. In this article, we study the problem of causal feature selection under sample selection bias and propose a novel Progressive Causal Feature Selection (PCFS) algorithm which has three phases. First, PCFS learns the sample weights to balance the treated group and control group distributions corresponding to each feature for removing spurious correlations. Second, based on the sample weights, PCFS uses a weighted cross-entropy model to estimate the causal effect of each feature and removes some irrelevant features from the confounder set. Third, PCFS progressively repeats the first two phases to remove more irrelevant features and finally obtains a causal feature set. Using synthetic and real-world datasets, the experiments have validated the effectiveness of PCFS, in comparison with several state-of-the-art classical and causal feature selection methods.<\/jats:p>","DOI":"10.1145\/3604809","type":"journal-article","created":{"date-parts":[[2023,6,17]],"date-time":"2023-06-17T08:41:08Z","timestamp":1686991268000},"page":"1-18","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":11,"title":["Causal Feature Selection in the Presence of Sample Selection Bias"],"prefix":"10.1145","volume":"14","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1837-0515","authenticated-orcid":false,"given":"Shuai","family":"Yang","sequence":"first","affiliation":[{"name":"Anhui Agricultural University, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0656-2309","authenticated-orcid":false,"given":"Xianjie","family":"Guo","sequence":"additional","affiliation":[{"name":"Hefei University of Technology, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2442-4572","authenticated-orcid":false,"given":"Kui","family":"Yu","sequence":"additional","affiliation":[{"name":"Hefei University of Technology, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7221-8055","authenticated-orcid":false,"given":"Xiaoling","family":"Huang","sequence":"additional","affiliation":[{"name":"Hefei University of Technology, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4561-8288","authenticated-orcid":false,"given":"Tingting","family":"Jiang","sequence":"additional","affiliation":[{"name":"Anhui Agricultural University, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1130-9391","authenticated-orcid":false,"given":"Jin","family":"He","sequence":"additional","affiliation":[{"name":"Anhui Agricultural University, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3768-8203","authenticated-orcid":false,"given":"Lichuan","family":"Gu","sequence":"additional","affiliation":[{"name":"Anhui Agricultural University, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2023,8,11]]},"reference":[{"key":"e_1_3_1_2_2","volume-title":"Proceedings of the American Medical Informatics Association Annual Symposium","author":"Aliferis Constantin F.","year":"2003","unstructured":"Constantin F.
