Researchers usually focus on the effectiveness of recommendation (e.g., precision) but neglect the popularity bias that may affect the fairness of the recommendation, which is also an important consideration that could influence the benefits of users and item providers. A few studies have been proposed to deal with the popularity bias, but they often face two limitations. Firstly, most studies only consider fairness for one side\u2014either users or items, without achieving fairness jointly for both. Secondly, existing methods are not sufficiently tailored to each individual user or item to cope with the varying extent and nature of popularity bias. To alleviate these limitations, in this paper, we propose\n            <jats:sans-serif>FAiR<\/jats:sans-serif>\n            , a\n            <jats:bold>f<\/jats:bold>\n            airness-centric model that\n            <jats:bold>a<\/jats:bold>\n            dapt\n            <jats:bold>i<\/jats:bold>\n            vely mitigates the popularity bias in both users and items for\n            <jats:bold>r<\/jats:bold>\n            ecommendation. Concretely, we design explicit fairness discriminators to mitigate the popularity bias for each user and item locally, and an implicit discriminator to preserve fairness globally. Moreover, we dynamically adapt the model to different input users and items to handle the differences in their popularity bias. Finally, we conduct extensive experiments to demonstrate that our model significantly outperforms state-of-the-art baselines in fairness metrics, while remaining competitive in effectiveness.\n          <\/jats:p>","DOI":"10.1145\/3564286","type":"journal-article","created":{"date-parts":[[2022,9,19]],"date-time":"2022-09-19T12:01:20Z","timestamp":1663588880000},"page":"1-27","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":35,"title":["Mitigating Popularity Bias for Users and Items with Fairness-centric Adaptive Recommendation"],"prefix":"10.1145","volume":"41","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3345-1719","authenticated-orcid":false,"given":"Zhongzhou","family":"Liu","sequence":"first","affiliation":[{"name":"School of Computing and Information Systems, Singapore Management University, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4265-5289","authenticated-orcid":false,"given":"Yuan","family":"Fang","sequence":"additional","affiliation":[{"name":"School of Computing and Information Systems, Singapore Management University, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0977-3600","authenticated-orcid":false,"given":"Min","family":"Wu","sequence":"additional","affiliation":[{"name":"Institute for Infocomm Research, A*STAR, Singapore"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"320","published-online":{"date-parts":[[2023,2,7]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1145\/3109859.3109912"},{"key":"e_1_3_2_3_2","first-page":"7","volume-title":"ACM KDD\u201920 Workshop on Industrial Recommendation Systems","author":"Abdollahpouri Himan","year":"2020","unstructured":"Himan Abdollahpouri and Masoud Mansoury. 2020.
