The system uses time-delay embeddings to rebuild the underlying \"attractor\" - the geometric shape describing how a chaotic system evolves over time - even when available data is sparse and disconnected. In tests on simulated and real-world chaotic systems, including the Lorenz96 climate model, PhyxMamba beat the strongest existing baseline by more than 44% in prediction accuracy and 8% in topological fidelity. It also held up against partial observations and noisy input, conditions that typically break older methods.\n\nThat data-scarcity problem is not a minor inconvenience. Chaotic systems show up in the fields scientists care most about - climate, neuroscience, fluid dynamics - and in all of them, long, clean recordings are expensive or outright impossible to collect. Reservoir computing, the prior go-to approach, needs long synchronization windows just to locate where a system sits on its attractor, which is exactly the kind of data these fields rarely have.\n\nWhether PhyxMamba generalizes from clean benchmark systems to messier real-world sensor streams is the open question this paper does not settle.","[\"ai\",\"research\",\"state-space-models\",\"chaos-theory\"]","2026-08-18T04:00:00.000Z","2026-08-19T00:50:36.565Z","2026-08-19T00:50:48.423Z","published",null,[],"ai",[24,26,27,28],"research","state-space-models","chaos-theory",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2505.23863",0,{"sections":35},[36,40,44,49,54,59,64,69,74,78,83,88,93,98],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",3293,"2026-08-20T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":39},"Security","security",435,{"name":45,"slug":46,"count":47,"latest_published_at":48},"Policy","policy",210,"2026-08-19T09:32:27.000Z",{"name":50,"slug":51,"count":52,"latest_published_at":53},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":55,"slug":56,"count":57,"latest_published_at":58},"Hardware","hardware",140,"2026-08-19T18:25:42.000Z",{"name":60,"slug":61,"count":62,"latest_published_at":63},"Consumer Tech","consumer-tech",95,"2026-08-18T16:05:00.000Z",{"name":65,"slug":66,"count":67,"latest_published_at":68},"Science","science",90,"2026-08-19T18:41:02.000Z",{"name":70,"slug":71,"count":72,"latest_published_at":73},"Software","software",73,"2026-08-18T07:51:50.000Z",{"name":75,"slug":76,"count":77,"latest_published_at":18},"Dev Tools","dev-tools",69,{"name":79,"slug":80,"count":81,"latest_published_at":82},"Startups","startups",47,"2026-08-19T19:13:46.000Z",{"name":84,"slug":85,"count":86,"latest_published_at":87},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",33,"2026-08-18T22:18:13.000Z",{"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"]
