Under the 0-load condition in a noise-free environment, the diagnostic accuracy of this model reached 99.66%, and the running time was only 52.74 s. Then, a bearing dataset with added Gaussian noise from \u22124 db to 4 db was verified, and this model was still able to maintain a diagnostic accuracy of 90.32% under the strong-noise environment of \u22124 db SNR. And migration experiments were carried out under different load conditions, and this model was also able to maintain a very high accuracy rate. Moreover, in all the above experiments, this model performed better than various comparative models. The developed framework demonstrated superior diagnostic precision, enhanced robustness, and improved generalization capability.<\/jats:p>","DOI":"10.3390\/s25113458","type":"journal-article","created":{"date-parts":[[2025,6,2]],"date-time":"2025-06-02T08:34:13Z","timestamp":1748853253000},"page":"3458","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Research on Bearing Fault Diagnosis Based on GMNR and ResNet-CABA-MAGRU"],"prefix":"10.3390","volume":"25","author":[{"given":"Longfa","family":"Chen","sequence":"first","affiliation":[{"name":"School of Intelligent Equipment, Shandong University of Science and Technology, Tai\u2019an 271019, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Na","family":"Meng","sequence":"additional","affiliation":[{"name":"School of Intelligent Equipment, Shandong University of Science and Technology, Tai\u2019an 271019, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenzheng","family":"Sun","sequence":"additional","affiliation":[{"name":"School of Intelligent Equipment, Shandong University of Science and Technology, Tai\u2019an 271019, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sen","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Intelligent Equipment, Shandong University of Science and Technology, Tai\u2019an 271019, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuo","family":"Tian","sequence":"additional","affiliation":[{"name":"School of Intelligent Equipment, Shandong University of Science and Technology, Tai\u2019an 271019, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuguo","family":"Li","sequence":"additional","affiliation":[{"name":"School of Intelligent Equipment, Shandong University of Science and Technology, Tai\u2019an 271019, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,5,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"110545","DOI":"10.1016\/j.ymssp.2023.110545","article-title":"Wavelet transform for rotary machine fault diagnosis:10 years revisited","volume":"200","author":"Yan","year":"2023","journal-title":"Mech.
