They found that when you feed these models overlapping, time-shifted versions of the same input, the models often produce different predictions for the exact same future timestamp, a consistency problem that standard error metrics like mean squared error don't even measure. To catch it, the team built a new metric called TAM (Time Alignment Metric), which checks whether a model agrees with itself across overlapping forecasts rather than just checking how close it lands to the truth. Applying AliO to existing models cut that self-contradiction by up to 58.2% and, in a bonus result, improved raw forecasting accuracy by up to 27.5% in some tests.\n\nMost forecasting benchmarks reward being close to the right answer on average, not being internally consistent. A model that predicts a 30% chance of rain for next Tuesday one day and 60% the next, using almost the same data, can still score well on MSE while being useless for anyone trying to plan around it. That gap between benchmark performance and real-world trustworthiness is exactly what keeps forecasting tools out of decisions that matter.\n\nThe fix also doubles as a quiet admission: the field has spent years optimizing for a number that was never measuring the thing people actually care about.","[\"time-series-forecasting\",\"machine-learning\",\"ai-research\",\"forecasting-models\"]","2026-10-09T04:00:00.000Z","2026-10-09T18:27:27.496Z","2026-10-09T18:27:31.675Z","published",null,[],"ai",[26,27,28,29],"time-series-forecasting","machine-learning","ai-research","forecasting-models",[31],{"name":32,"url":33},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2610.11213",0,{"sections":36},[37,40,44,49,54,59,63,68,73,78,83,88,93,98],{"name":38,"slug":24,"count":39,"latest_published_at":18},"AI",6608,{"name":41,"slug":42,"count":43,"latest_published_at":18},"Security","security",926,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",486,"2026-10-08T22:40:11.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",474,"2026-10-08T22:00:00.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",229,"2026-10-08T20:47:10.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":18},"Science","science",192,{"name":64,"slug":65,"count":66,"latest_published_at":67},"Consumer Tech","consumer-tech",181,"2026-10-08T23:26:35.000Z",{"name":69,"slug":70,"count":71,"latest_published_at":72},"Startups","startups",117,"2026-10-08T16:45:00.000Z",{"name":74,"slug":75,"count":76,"latest_published_at":77},"Software","software",114,"2026-10-08T17:57:01.000Z",{"name":79,"slug":80,"count":81,"latest_published_at":82},"Dev Tools","dev-tools",105,"2026-10-07T16:59:11.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"General","general",66,"2026-10-09T04:46:11.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"Gaming","gaming",58,"2026-10-08T20:08:45.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",34,"2026-10-08T14:00:22.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",8,"2026-10-05T09:00:00.000Z"]
