The key mechanism is the Radiomics Attention Gate, which uses those handcrafted features to steer where the model pays attention during segmentation, rather than letting the network figure it out from scratch. On the Breast Ultrasound Images dataset, it scored a Dice Similarity Coefficient of 0.763; on the Kvasir-SEG colonoscopy dataset, 0.854 — beating the competing U-KAN architecture by 1.2% and 1.8%, respectively. It does this with 3.27 million parameters, roughly 9.5 times fewer than a standard U-Net.\n\nThe interpretability angle is the real story. Most attempts to explain deep learning decisions in clinical settings rely on post-hoc approximations — explanations applied after the model has already decided. RadiomicNet bakes explanation in from the start, and gradient analysis confirms that specific texture metrics like GLCM dissimilarity drive the decisions in quantifiable ways. That matters because regulators and clinicians increasingly demand to know not just what an AI concluded, but why.\n\nMedical AI has a long history of trading accuracy for efficiency or vice versa — RadiomicNet is a credible argument that domain knowledge can close that gap, though peer-reviewed clinical validation on larger, more diverse datasets will be the real test.","[\"ai\",\"medical imaging\",\"deep learning\",\"interpretability\"]","2026-07-03T04:00:00.000Z","2026-07-03T08:03:29.548Z","2026-07-03T08:03:32.466Z","published",null,[],"ai",[24,26,27,28],"medical imaging","deep learning","interpretability",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.02185",0,{"sections":35},[36,40,45,50,55,60,65,70,75,80,85,89,94,99],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Dev Tools","dev-tools",59,"2026-07-07T04:00:00.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":86,"slug":87,"count":83,"latest_published_at":88},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":90,"slug":91,"count":92,"latest_published_at":93},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":95,"slug":96,"count":97,"latest_published_at":98},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":100,"slug":101,"count":102,"latest_published_at":103},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
