However, existing FSL methods often rely on unimodal information under limited sample conditions, making it difficult to capture fine-grained differences between categories. To address this issue, we propose a multimodal few-shot learning method based on category name expansion and image feature enhancement. By integrating the expanded category text with image features, the proposed method enriches the semantic representation of categories and enhances the model\u2019s sensitivity to detailed features. To further improve the quality of cross-modal information transfer, we introduce a cross-modal residual connection strategy that aligns features across layers through progressive fusion. This approach enables the fused representations to maximize mutual information while reducing redundancy, effectively alleviating the information bottleneck caused by uneven entropy distribution between modalities and enhancing the model\u2019s generalization ability. Experimental results demonstrate that our method achieves superior performance on both natural image datasets (CIFAR-FS and FC100) and a medical image dataset.<\/jats:p>","DOI":"10.3390\/e27090991","type":"journal-article","created":{"date-parts":[[2025,9,22]],"date-time":"2025-09-22T17:08:17Z","timestamp":1758560897000},"page":"991","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Category Name Expansion and an Enhanced Multimodal Fusion Framework for Few-Shot Learning"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0009-0007-4340-8697","authenticated-orcid":false,"given":"Tianlei","family":"Gao","sequence":"first","affiliation":[{"name":"The College of Computer Science and Engineering, Shandong University of Science and Technology, Qingdao 266590, China"},{"name":"Shandong Artificial Intelligence Institute, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"},{"name":"School of Mathematics and Statistics, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Lei","family":"Lyu","sequence":"additional","affiliation":[{"name":"The School of Information Science and Engineering, Shandong Normal University, Jinan 250014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3137-5070","authenticated-orcid":false,"given":"Xiaoyun","family":"Xie","sequence":"additional","affiliation":[{"name":"Shandong Artificial Intelligence Institute, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"},{"name":"School of Mathematics and Statistics, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0005-8086-8786","authenticated-orcid":false,"given":"Nuo","family":"Wei","sequence":"additional","affiliation":[{"name":"Shandong Artificial Intelligence Institute, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"},{"name":"School of Mathematics and Statistics, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-7587-4242","authenticated-orcid":false,"given":"Yushui","family":"Geng","sequence":"additional","affiliation":[{"name":"The College of Computer Science and Engineering, Shandong University of Science and Technology, Qingdao 266590, China"},{"name":"School of Mathematics and Statistics, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0008-0014-3841","authenticated-orcid":false,"given":"Minglei","family":"Shu","sequence":"additional","affiliation":[{"name":"The College of Computer Science and Engineering, Shandong University of Science and Technology, Qingdao 266590, China"},{"name":"Shandong Artificial Intelligence Institute, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"},{"name":"School of Mathematics and Statistics, Qilu University of Technology (Shandong Academy of Sciences), Jinan 250014, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,9,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"103875","DOI":"10.1016\/j.artint.2023.103875","article-title":"Towards well-generalizing meta-learning via adversarial task augmentation","volume":"317","author":"Wang","year":"2023","journal-title":"Artif.
