The existing feature representation-based methods mainly solve the problem of inconsistent feature distribution between the source domain data and the target domain data, but only a few methods analyze the correlation of cross-domain features between the original space and shared latent space, which reduces the performance of domain adaptation. To this end, we propose a domain adaptation method with a residual module, the main ideas of which are as follows: (1) transfer the source domain data features to the target domain data through the shared latent space to achieve features sharing; (2) build a cross-domain residual learning model using the latent feature space as the residual connection of the original feature space, which improves the propagation efficiency of features; (3) use a regular feature space to sparse feature representation, which can improve the robustness of the model; and (4) give an optimization algorithm, and the experiments on the public visual datasets (Office31, Office-Caltech, Office-Home, PIE, MNIST-UPS, COIL20) results show that our method achieved 92.7% accuracy on Office-Caltech and 83.2% on PIE and achieved the highest recognition accuracy in three datasets, which verify the effectiveness of the method.<\/jats:p>","DOI":"10.3390\/info16100852","type":"journal-article","created":{"date-parts":[[2025,10,2]],"date-time":"2025-10-02T08:20:28Z","timestamp":1759393228000},"page":"852","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Cross-Domain Residual Learning for Shared Representation Discovery"],"prefix":"10.3390","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2491-3723","authenticated-orcid":false,"given":"Baoqi","family":"Zhao","sequence":"first","affiliation":[{"name":"School of Artificial Intelligence, Ningbo Polytechnic University, Ningbo 315800, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Pan","sequence":"additional","affiliation":[{"name":"School of Artificial Intelligence, Ningbo Polytechnic University, Ningbo 315800, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhijie","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Information Science and Technology, Hangzhou Normal University, Hangzhou 311121, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fang","family":"Yang","sequence":"additional","affiliation":[{"name":"Ningbo University Health Science Center, Ningbo University, Ningbo 315211, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,10,2]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Huang, J., Smola, A., Gretton, A., Borgwardt, K., and Scholkopf, B.
