For the Lorenz chaos, by optimizing the transfer rate, we accomplish more accurate inference than the conventional method by an order of magnitude. Moreover, a surprisingly small amount of learning is enough to infer the energy dissipation rate of the Navier-Stokes turbulence because we can, thanks to the small-scale universality of turbulence, transfer a large amount of the knowledge learned from turbulence data at lower Reynolds number.", "revisions": [ { "version": "v1", "updated": "2020-09-03T01:40:56.000Z" } ], "analyses": { "subjects": [ "68T01", "76F65", "37N10", "I.2", "J.2" ], "keywords": [ "nonlinear dynamics", "fluid turbulence", "transfer learning", "application", "enables efficient predictions" ], "note": { "typesetting": "TeX", "pages": 8, "language": "en", "license": "arXiv", "status": "editable" } } }
