Instead of just a label and a confidence number, DENet outputs a predicted vibration frequency that can be checked against the theoretical value calculated from bearing geometry and shaft speed, plus a time-stamped location of the impulse on the raw waveform. Tested across four different encoder models and three public datasets, the extra evidence cost no statistically significant accuracy, with frequency estimates typically off by about 6 Hz on 1,024-point signal segments. A QLoRA-adapted language model then turns that evidence into maintenance reports, a step it does not use to make decisions.\n\nThe frequency mismatch works as a built-in lie detector: when the predicted and theoretical frequencies diverge, that gap flags misclassifications with AUROC scores of 0.970 and 0.871 across the tested setups, and the separation holds even within the high-confidence subset. It also curbed the language model's tendency to invent claims in its reports, cutting unsupported statements from 10-12% down to 2%, with no fabricated numbers observed.\n\nConfidence scores have always measured how sure a model is, not whether it's right - this is one of the more concrete attempts to close that gap with actual physics instead of more statistics.","[\"ai\",\"manufacturing\",\"predictive maintenance\",\"explainable ai\"]","2026-09-25T04:00:00.000Z","2026-09-26T01:19:24.622Z","2026-09-26T01:19:30.599Z","published",null,[],"ai",[24,26,27,28],"manufacturing","predictive maintenance","explainable ai",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.22797",0,{"sections":35},[36,40,45,50,55,60,65,70,75,80,85,90,95,100],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",4536,"2026-09-25T17:16:30.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",741,"2026-09-25T15:52:13.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Policy","policy",390,"2026-09-25T16:24:59.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Deals","deals",256,"2026-09-25T17:00:53.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",185,"2026-09-25T15:00:22.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Science","science",140,"2026-09-25T11:55:23.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Consumer Tech","consumer-tech",132,"2026-09-25T15:30:00.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Software","software",88,"2026-09-24T23:06:55.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":79},"Dev Tools","dev-tools",82,"2026-09-25T09:59:40.000Z",{"name":81,"slug":82,"count":83,"latest_published_at":84},"Startups","startups",76,"2026-09-25T18:33:59.000Z",{"name":86,"slug":87,"count":88,"latest_published_at":89},"Gaming","gaming",48,"2026-09-25T18:35:21.000Z",{"name":91,"slug":92,"count":93,"latest_published_at":94},"General","general",46,"2026-09-25T02:12:57.000Z",{"name":96,"slug":97,"count":98,"latest_published_at":99},"Reviews","reviews",30,"2026-09-24T20:07:31.000Z",{"name":101,"slug":102,"count":103,"latest_published_at":104},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
