They trained those new encoders end-to-end while keeping TabPFN itself frozen, and added a contrastive alignment step that forces the two data types into a shared format the frozen model already understands. A gated shortcut also lets a simpler tabular-only prediction back up the combined result. On a 2,240-patient dataset from the Alzheimer's Disease Neuroimaging Initiative, the model sorted patients into cognitively normal, mildly impaired, or Alzheimer's categories with 65.55% macro-F1 and 82.21% macro-AUC, beating the other single-source and multi-source models it was tested against.\n\nThe bigger claim is generalization: the same architecture, with only its output head swapped, predicted cognitive test scores with a mean error of 1.743 points on a separate 1,250-patient group. It also held up on two outside hospital datasets, OASIS-3 and SCAN, without any retraining, even when the cognitive test used to score patients changed. Most medical AI models degrade sharply when moved to a new hospital, scanner, or patient population, which is the exact failure mode that has kept many diagnostic tools out of real clinical use.\n\nThis is still a research paper, not a cleared diagnostic device, and three test cohorts is a start rather than proof. But a model that keeps working when the hospital, the scanner, and even the test instrument change is a more useful signal than another leaderboard score.","[\"alzheimers\",\"multimodal-ai\",\"medical-ai\",\"in-context-learning\"]","2026-09-25T04:00:00.000Z","2026-09-26T00:15:57.377Z","2026-09-26T00:16:02.596Z","published",null,[],"ai",[26,27,28,29],"alzheimers","multimodal-ai","medical-ai","in-context-learning",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2609.28836",0,{"sections":36},[37,41,46,51,56,61,66,71,76,81,86,91,96,101],{"name":38,"slug":24,"count":39,"latest_published_at":40},"AI",4536,"2026-09-25T17:16:30.000Z",{"name":42,"slug":43,"count":44,"latest_published_at":45},"Security","security",741,"2026-09-25T15:52:13.000Z",{"name":47,"slug":48,"count":49,"latest_published_at":50},"Policy","policy",390,"2026-09-25T16:24:59.000Z",{"name":52,"slug":53,"count":54,"latest_published_at":55},"Deals","deals",256,"2026-09-25T17:00:53.000Z",{"name":57,"slug":58,"count":59,"latest_published_at":60},"Hardware","hardware",185,"2026-09-25T15:00:22.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Science","science",140,"2026-09-25T11:55:23.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Consumer Tech","consumer-tech",132,"2026-09-25T15:30:00.000Z",{"name":72,"slug":73,"count":74,"latest_published_at":75},"Software","software",88,"2026-09-24T23:06:55.000Z",{"name":77,"slug":78,"count":79,"latest_published_at":80},"Dev Tools","dev-tools",82,"2026-09-25T09:59:40.000Z",{"name":82,"slug":83,"count":84,"latest_published_at":85},"Startups","startups",76,"2026-09-25T18:33:59.000Z",{"name":87,"slug":88,"count":89,"latest_published_at":90},"Gaming","gaming",48,"2026-09-25T18:35:21.000Z",{"name":92,"slug":93,"count":94,"latest_published_at":95},"General","general",46,"2026-09-25T02:12:57.000Z",{"name":97,"slug":98,"count":99,"latest_published_at":100},"Reviews","reviews",30,"2026-09-24T20:07:31.000Z",{"name":102,"slug":103,"count":104,"latest_published_at":105},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
