1: ntawm lossis cuam tshuam rau cov txheej txheem uas txhua ntu lossis cov qauv loj yog tus sawv cev sib npaug ntawm tag nrho(raws li hais txog qhov ntsuas ntsuas) 2: cuam tshuam lossis cuam tshuam rau qhov tshwm sim uas ib lub xeev yuav rov tshwm sim tshwj xeeb: muaj pes tsawg qhov tshwm sim uas ib lub xeev yuav tsis rov muaj dua.
Koj piav qhia txog kev ua haujlwm li cas?
Ergodicity yog dab tsi? Qhov kev sim xav no yog ib qho piv txwv ntawm ergodicity. Txhua tus neeg ua yeeb yam koom nrog hauv qhov system tuaj yeem txhais tau tias yog ergodic lossis tsis yog ergodic. Hauv qhov xwm txheej ergodic, qhov txiaj ntsig nruab nrab ntawm pawgyog tib yam li qhov txiaj ntsig nruab nrab ntawm tus neeg dhau sijhawm.
Vim li cas ergodicity tseem ceeb?
Nov yog ib qho tseem ceeb heev khoom tseem ceeb rau kev txheeb xyuas cov kws kho tsheb. Qhov tseeb, tus tsim ntawm statistical mechanics, Ludwig Boltzmann, coined "ergodic" raws li lub npe rau ib tug muaj zog tab sis muaj feem xyuam rau cov cuab yeej: pib los ntawm ib tug random point nyob rau hauv lub xeev qhov chaw, orbits feem ntau yuav dhau los ntawm txhua qhov chaw hauv lub xeev.
txhais li cas los ntawm ergodicity hauv kev sib txuas lus digital?
Nyob rau hauv econometrics thiab teeb liab ua, cov txheej txheem stochastic tau hais tias yog ergodic yog tias nws cov ntaub ntawv txheeb cais tuaj yeem txiav tawm los ntawm ib qho, ntev txaus, random qauv ntawm cov txheej txheem. … Hloov pauv, tus txheej txheem uas tsis yog ergodic yog txheej txheem uas hloov pauv ntawm qhov tsis sib xws.
Dab tsi yog txheej txheem ergodic muab qhov tseeblub neej piv txwv?
Nkauj tuag tsis tu ncua 6 lub ntsej muag. Pov ib npib ib txwm. Yog tias tsis muaj dab tsi sab nraud sim cuam tshuam qhov tshwm sim (ib qho pom tsis pom uas ntes cov neeg tuag thiab qhia qee lub ntsej muag ntawm nws qhov kev xaiv), koj yuav tsim cov txheej txheem ergodic.
