A: Hauv tshuab kev kawm , ib " random taug kev "Txoj kev tuaj yeem siv tau rau ntau txoj hauv kev los pab cov thev naus laus zis los ntawm cov ntaub ntawv kev cob qhia loj uas muab lub hauv paus rau tshuab cov kev nkag siab ntawm qhov kawg. A random taug kev , lej, yog ib yam uas tuaj yeem piav qhia ntau txoj hauv kev.
Ib yam li ntawd, dab tsi yog kev taug kev hauv kev txheeb cais?
A random taug kev yog hais txog txhua tus txheej txheem uas tsis muaj kev pom zoo los yog qauv; uas yog, qhov twg qhov kev txav ntawm ib qho khoom, lossis qhov tseem ceeb coj los ntawm ib qho kev sib txawv, yog kiag li random.
Ib yam li ntawd, random taug kev algorithm yog dab tsi? Cov Random Taug kev algorithm . Random Taug kev yog ib algorithm uas muab random paths nyob rau hauv ib daim duab. A random taug kev txhais tau hais tias peb pib ntawm ib lub node, xaiv ib tug neeg nyob ze rau navigate rau ntawm random los yog raws li qhov yuav tsum tau muab faib, thiab tom qab ntawd ua tib yam los ntawm cov node, khaws txoj kev tshwm sim hauv ib daim ntawv teev npe.
Khaws qhov no hauv kev txiav txim siab, puas yog kev taug kev mus rau Markov saw?
Markov chains thiab random taug kev yog cov piv txwv ntawm random txheej txheem i.e. ib qho indexed sau ntawm random sib txawv. Markov chains thiab random taug kev yog cov piv txwv ntawm random txheej txheem i.e. ib qho indexed sau ntawm random sib txawv. A random taug kev yog ib hom tshwj xeeb random txheej txheem ua los ntawm ib tug sum ntawm id random sib txawv.
Dab tsi yog hav zoov random yog random taug kev nyob ruaj khov lossis tsis yog vim li cas?
Tsis muaj , yog tsis yog . Random Taug kev yog tsis nyob ruaj ruaj . Tab sis tsis yog tag nrho tsis nyob ruaj ruaj cov txheej txheem yog random taug kev . A tsis nyob ruaj ruaj lub sij hawm series lub ntsiab lus thiab/los yog variance yog tsis yog tas li ntawm lub sijhawm.

Random Taug kev nrog Drift yog dab tsi?
Random taug kev nrog drift. Rau kev taug kev random nrog drift, qhov kev kwv yees zoo tshaj plaws ntawm tag kis tus nqi yog hnub no tus nqi ntxiv rau lub sijhawm drift. Ib tus tuaj yeem xav txog qhov drift raws li ntsuas qhov sib txawv ntawm tus nqi (tej zaum xav txog kev nce nqi mus sij hawm ntev). Muab qhov drift feem ntau yog suav tias yog tas li.

Vim li cas random taug kev tsis nyob ruaj khov?
Tsis yog, tsis yog. Random Taug kev tsis nyob ruaj khov. Tab sis tsis yog tag nrho cov txheej txheem tsis nyob ruaj ruaj yog taug kev random. Lub sij hawm tsis nyob ruaj ruaj qhov txhais tau tias thiab / lossis qhov sib txawv tsis tas li nyob rau lub sijhawm
Dab tsi yog cov ncauj lus hauv kev ua lej hauv tsev kawm qib siab?
Cov ntsiab lus tseem ceeb uas tau qhia hauv chav kawm no yog teeb tsa txoj kev xav, lub cim logic, geometry thiab kev ntsuas, kev qhia txog kev sib txuas lus, qhov yuav tshwm sim thiab piav qhia cov txheeb cais, thiab keeb kwm ntawm lej
Koj ua qauv random taug kev li cas?
Ib qho qauv yooj yim ntawm kev taug kev random yog raws li hauv qab no: Pib nrog tus lej random ntawm tog twg los -1 lossis 1. Random xaiv -1 lossis 1 thiab ntxiv rau qhov kev soj ntsuam los ntawm cov kauj ruam dhau los. Rov ua kauj ruam 2 kom ntev npaum li koj nyiam
Koj kawm li cas rau chav kawm biology hauv tsev kawm qib siab?
