The existing prediction models typically require large\u2010scale and high\u2010quality historical data to achieve better performance. However, insufficient data volume and significant differences between data distribution across different regions will definitely reduce the effectiveness of the model reuse. To address the above issues, we propose a novel hybrid recurrent network based on domain adversarial transfer to achieve a stronger generalization ability when training air quality data from multisource domains. The proposed model mainly consists of three fundamental modules, i.e., feature extractor, regression predictor, and domain classifier. One\u2010dimensional convolutional neural networks (1D\u2010CNNs) are used to extract temporal feature of data from source and target stations. Bi\u2010directional gated recurrent unit (bi\u2010GRU) and bi\u2010directional long short\u2010term memory (bi\u2010LSTM) are utilized to learn temporal dependencies pattern of multivariate time series data. Two adversarial transfer strategies are employed to ensure that our model is capable of finding domain invariant representations automatically. Experiments with different number of source domains are conducted to demonstrate the effectiveness of the proposed domain transfer strategies. The experimental results also show that our composite model has superior performance for forecasting air quality in various regions. As further evidence, the adversarial training method could promote the positive transfer and alleviate the negative effect of irrelevant source data. Besides, our model exhibits preferable generalization capability as more robust prediction results are achieved on both unseen target domains and original source domains.<\/jats:p>","DOI":"10.1155\/int\/6014262","type":"journal-article","created":{"date-parts":[[2025,5,20]],"date-time":"2025-05-20T05:58:42Z","timestamp":1747720722000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Adversarial Transfer Learning\u2010Based Hybrid Recurrent Network for Air Quality Prediction"],"prefix":"10.1155","volume":"2025","author":[{"given":"Yanqi","family":"Hao","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4021-464X","authenticated-orcid":false,"given":"Chuan","family":"Luo","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tianrui","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junbo","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongmei","family":"Chen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,5,19]]},"reference":[{"key":"e_1_2_14_1_2","doi-asserted-by":"publisher","DOI":"10.3233\/ais-2010-0061"},{"key":"e_1_2_14_2_2","doi-asserted-by":"publisher","DOI":"10.1007\/s44230-023-00037-z"},{"key":"e_1_2_14_3_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11356-016-7812-9"},{"key":"e_1_2_14_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.eswa.2008.12.017"},{"key":"e_1_2_14_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.atmosenv.2014.12.011"},{"key":"e_1_2_14_6_2","volume-title":"Deep Learning for Time-Series Analysis","author":"Gamboa J.","year":"2017"},{"key":"e_1_2_14_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/tkde.2018.2823740"},{"key":"e_1_2_14_8_2","doi-asserted-by":"crossref","unstructured":"ZhengY.
