… continued from last post. The last set of cross-validation results are based on training of held-out data for intervals outside of 0.6-0.8 (i.e. training on t<0.6 and t>0.8 of the data, which extends from t=0.0 to t=1.0 normalized). This post considers training on intervals outside of 0.3-0.6 — a narrower training interval and correspondingly … Continue reading Simpler models … alternate interval| GeoEnergy Math
… continued from last post. Each fitted model result shows the cross-validation results based on training of held-out data — i.e. training on only the intervals outside of 0.6-0.8 (i.e. training on t<0.6 and t>0.8 of the data, which extends from t=0.0 to t=1.0 normalized). The best results are for time-series that have 100 years … Continue reading Simpler models … examples| GeoEnergy Math
Obwohl sich die Erde durch den Klimawandel insgesamt erwärmt, treten in Teilen der USA zunehmend eisige Winter mit extremem Schneefall und lebensbedrohlich tiefen Temperaturen auf. Welche Faktoren zu diesem lokalen Extremwetter beitragen, haben nun Klimaforscher herausgefunden. Demnach sind dafür zwei spezifische Muster des Polarwirbels hoch über der Arktis verantwortlich. Sie bestimmen, wann und wo ein Kälteeinbruch ... Weiterlesen Der Beitrag Ursache aktueller Kälteeinbrüche in den U...| AG E+U – Die Realisten
