Cov thawj qhov tsis zoo yog tias tej datasets yuav xaus nrog feem ntau ntawm cov cov ntaub ntawv Qhov tseem ceeb poob rau hauv ib lossis ob chav kawm xwb, thaum ob peb mus rau qhov tsis muaj nuj nqis yuav nyob hauv lwm chav kawm.
Ntawm no, dab tsi yog qhov tsis zoo ntawm kev faib tawm?
A qhov tsis zoo rau kev faib tawm yog qhov ntau ntawm cov kev faib tawm lawv tus kheej yog raws li cov kev txiav txim siab, uas tej zaum yuav los yog tsis tuaj yeem sib koom los ntawm txhua tus neeg koom. Qhov no yuav ua rau muaj qhov sib txawv ntawm qhov pom muaj txiaj ntsig.
Kuj Paub, plaub yam tseem ceeb ntawm kev faib tawm yog dab tsi? dab tsi yog qhov zoo ntawm kev faib cov ntaub ntawv
- Yooj yim.
- Luv luv.
- Kev siv hluav taws xob.
- Kev sib piv.
- Txaus nyiam thiab siv tau.
- Kev Kawm Txuj Ci.
Tom qab ntawd, qhov zoo ntawm kev faib cov ntaub ntawv yog dab tsi?
Kev siv cov kev faib cov ntaub ntawv zoo ib yam yuav pab txhawb kev lag luam kom zoo dua qub, thiab txo cov nqi ntawm kev ua kom cov ntaub ntawv txaus kev ruaj ntseg . Los ntawm kev faib cov ntaub ntawv, koj lub koom haum tuaj yeem npaj los txheeb xyuas qhov pheej hmoo thiab cuam tshuam ntawm qhov xwm txheej raws li hom ntaub ntawv twg koom nrog.
Dab tsi yog qhov tsis zoo ntawm cov ntaub ntawv mining?
Kev txwv lossis qhov tsis zoo ntawm Cov Ntaub Ntawv Mining Techniques:
