Tested on 1,195 interaction records from 27 students across 45 tasks, a basic logistic regression model hit an AUC-ROC of 0.903, edging out the fancier LightGBM classifier at 0.878. The headline finding is that students are reliably overconfident: their calibration error score (0.109) was nearly double the model's own error rate (0.068).\n\nThe harder problem UBP-CAP is trying to solve is interpretability — specifically, whether the features that predict a correct answer are the same features that explain *why* a student is miscalibrated. A new index called PEDI measures that divergence, and here it came back near zero, suggesting the behavioral signals that forecast correctness largely overlap with those that reveal self-assessment gaps. That alignment matters because it means a single sensor suite could theoretically drive both personalization and feedback in a tutoring system.\n\nThe caveat is scale: 27 students is a proof-of-concept sample, and the crossed model finding that calibration is situational rather than a stable trait could look very different with thousands of learners across varied subjects. Intelligent tutoring research has a long history of promising pipelines that don't survive contact with a real classroom.","[\"machine learning\",\"education\",\"ai\",\"research\"]","2026-06-30T04:00:00.000Z","2026-06-30T09:44:50.874Z","2026-06-30T09:44:53.826Z","published",null,[],"ai",[26,27,24,28],"machine learning","education","research",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2606.28881",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"]
