Existing methods predominantly rely on fusion-based multimodal deep learning, effectively integrating linguistic and acoustic features. However, these methods inadequately model higher-order interactions between modalities, reducing diagnostic accuracy. To address this, we introduce SpeechHGT, a multimodal hypergraph transformer designed to capture and learn higher-order interactions in spontaneous speech features. SpeechHGT encodes multimodal features as hypergraphs, where nodes represent individual features and hyperedges represent grouped interactions. A novel hypergraph attention mechanism enables robust modeling of both pairwise and higher-order interactions. Experimental evaluations on the DementiaBank datasets reveal that SpeechHGT achieves state-of-the-art performance, surpassing baseline models in accuracy and F1 score. These results highlight the potential of hypergraph-based models to improve AI-driven diagnostic tools for early AD detection.<\/jats:p>","DOI":"10.24963\/ijcai.2025\/1015","type":"proceedings-article","created":{"date-parts":[[2025,9,19]],"date-time":"2025-09-19T08:10:40Z","timestamp":1758269440000},"page":"9131-9139","source":"Crossref","is-referenced-by-count":1,"title":["SpeechHGT: A Multimodal Hypergraph Transformer for Speech-Based Early Alzheimer\u2019s Disease Detection"],"prefix":"10.24963","author":[{"given":"Shagufta","family":"Abid","sequence":"first","affiliation":[{"name":"Dalian University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dongyu","family":"Zhang","sequence":"additional","affiliation":[{"name":"Dalian University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahsan","family":"Shehzad","sequence":"additional","affiliation":[{"name":"Dalian University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jing","family":"Ren","sequence":"additional","affiliation":[{"name":"RMIT University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shuo","family":"Yu","sequence":"additional","affiliation":[{"name":"Dalian University of Technology"},{"name":"Key Laboratory of Social Computing and Cognitive Intelligence, Ministry of Education"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongfei","family":"Lin","sequence":"additional","affiliation":[{"name":"Dalian University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Feng","family":"Xia","sequence":"additional","affiliation":[{"name":"RMIT University"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"10584","event":{"name":"Thirty-Fourth International Joint Conference on Artificial Intelligence {IJCAI-25}","theme":"Artificial Intelligence","location":"Montreal, Canada","acronym":"IJCAI-2025","number":"34","sponsor":["International Joint Conferences on Artificial Intelligence Organization (IJCAI)"],"start":{"date-parts":[[2025,8,16]]},"end":{"date-parts":[[2025,8,22]]}},"container-title":["Proceedings of the Thirty-Fourth International Joint Conference on Artificial Intelligence"],"original-title":[],"deposited":{"date-parts":[[2025,9,23]],"date-time":"2025-09-23T11:35:51Z","timestamp":1758627351000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ijcai.org\/proceedings\/2025\/1015"}},"subtitle":[],"proceedings-subject":"Artificial Intelligence Research Articles","short-title":[],"issued":{"date-parts":[[2025,9]]},"references-count":0,"URL":"https:\/\/doi.org\/10.24963\/ijcai.2025\/1015","relation":{},"subject":[],"published":{"date-parts":[[2025,9]]}}}
