Existing models lean on time-series diagnostic signals, but visible-light camera images add useful spatial information: plasma deformation, localized brightening, radiation patterns. The problem is that processing images at inference time is expensive. The new framework, tested on 640 discharges from China's EAST tokamak, sidesteps that tradeoff by training a multimodal \"teacher\" model on both images and sensor signals, then distilling that knowledge into a leaner \"student\" model that runs on sensor data alone.\n\nThe distillation happens at three levels — graph structure, internal representations, and final decisions — so the student model inherits the teacher's spatial intuition without needing a camera feed at runtime. That matters because fusion reactors need real-time disruption warnings; a model that is too slow or compute-hungry to deploy continuously is not useful in practice.\n\nFusion energy has attracted serious capital in recent years, and as commercial reactors move closer to reality, the gap between research-grade AI and production-ready safety systems becomes harder to ignore. A distillation approach that preserves accuracy while slashing inference cost is a step toward closing it — though 640 discharges is a modest dataset, and real-world generalization across reactor designs remains an open question.","[\"fusion energy\",\"machine learning\",\"safety\",\"hardware\"]","2026-07-07T04:00:00.000Z","2026-07-07T12:21:01.440Z","2026-07-07T12:21:04.410Z","published",null,[],"science",[26,27,28,29],"fusion energy","machine learning","safety","hardware",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2607.04241",0,{"sections":36},[37,42,47,52,57,61,66,71,75,79,84,88,93,98],{"name":38,"slug":39,"count":40,"latest_published_at":41},"AI","ai",2590,"2026-07-16T04:00:00.000Z",{"name":43,"slug":44,"count":45,"latest_published_at":46},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":48,"slug":49,"count":50,"latest_published_at":51},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":53,"slug":54,"count":55,"latest_published_at":56},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":58,"slug":29,"count":59,"latest_published_at":60},"Hardware",122,"2026-07-14T19:46:26.000Z",{"name":62,"slug":63,"count":64,"latest_published_at":65},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":67,"slug":68,"count":69,"latest_published_at":70},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":72,"slug":24,"count":73,"latest_published_at":74},"Science",66,"2026-07-10T10:29:37.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":18},"Dev Tools","dev-tools",59,{"name":80,"slug":81,"count":82,"latest_published_at":83},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":85,"slug":86,"count":82,"latest_published_at":87},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
