In this study, we propose a lightweight deep learning model\u2014Improved Deep Residual Network (IDRN)\u2014combined with hyperspectral imaging (HSI) to achieve precise identification of gastric cancer tissues. The model incorporates spectral preprocessing, dimensionality reduction, and a residual CNN with attention mechanisms to enhance feature extraction while maintaining efficiency. Comparative experiments with SVM, ResNet50, and ViT models show that IDRN achieves superior performance, particularly in identifying poorly differentiated tissues. Our approach provides a promising tool for computer\u2010aided diagnosis and offers potential for clinical translation.<\/jats:p>","DOI":"10.1002\/jbio.202500242","type":"journal-article","created":{"date-parts":[[2025,9,4]],"date-time":"2025-09-04T03:54:16Z","timestamp":1756958056000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Precise Identification of Gastric Cancer Pathological Differentiation Based on Hyperspectral Imaging and Lightweight Deep Learning Models"],"prefix":"10.1002","volume":"19","author":[{"given":"Yutao","family":"Ma","sequence":"first","affiliation":[{"name":"Department of Gastroenterology Dezhou Hospital, Qilu Hospital, Shandong University  Dezhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ruoyu","family":"Zhou","sequence":"additional","affiliation":[{"name":"School of Clinical Medicine Shandong Second Medical University  Weifang China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhengshuai","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Control Science and Engineering Shandong University  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chongxuan","family":"Tian","sequence":"additional","affiliation":[{"name":"School of Control Science and Engineering Shandong University  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rui","family":"Meng","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Dezhou Hospital, Qilu Hospital, Shandong University  Dezhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuyan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Dezhou Hospital, Qilu Hospital, Shandong University  Dezhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7367-4178","authenticated-orcid":false,"given":"Wei","family":"Li","sequence":"additional","affiliation":[{"name":"School of Control Science and Engineering Shandong University  Jinan China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongbo","family":"Ren","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology Dezhou Hospital, Qilu Hospital, Shandong University  Dezhou China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2025,9,3]]},"reference":[{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.6004\/jnccn.2022.0008"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.3322\/caac.21834"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/his.13975"},{"issue":"3","key":"e_1_2_8_5_1","first-page":"251","article-title":"Gastric Cancer: Classification, Histology and Application of Molecular Pathology","volume":"3","author":"Hu B.","year":"2012","journal-title":"Journal of Gastrointestinal Oncology"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1159\/000527992"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.3760\/cma.j.issn.0366-6999.20123235"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1365-2036.2005.02425.x"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1111\/den.13684"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1093\/ije\/26.4.716"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1055\/a-1350-5583"},{"key":"e_1_2_8_12_1","doi-asserted-by":"publisher","DOI":"10.1039\/D0AY01023E"},{"key":"e_1_2_8_13_1","doi-asserted-by":"publisher","DOI":"10.1002\/jbio.202300276"},{"key":"e_1_2_8_14_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.cmpb.2024.108285"},{"key":"e_1_2_8_15_1","doi-asserted-by":"publisher","DOI":"10.1002\/jbio.202300254"},{"key":"e_1_2_8_16_1","volume-title":"Proceedings of the 10th Airborne Earth Science Workshop","author":"Clark R.
