Ib tug kuj yuav nug, hom ntaub ntawv sib txawv yog dab tsi? Muaj ob hom ntaub ntawv qhov chaw : tshuab cov ntaub ntawv thiab ua ntaub ntawv cov ntaub ntawv . Txawm hais tias ob qho tib si muaj cov ntaub ntawv zoo sib xws ntawm cov qhov chaw ntawm cov ntaub ntawv , lawv txawv ntawm qhov kev khaws cov ntaub ntawv no. Vim tias qhov sib txawv no, lawv tau siv qee yam txawv kev coj ncaj ncees.

Tom qab ntawd, cov ntaub ntawv sib txawv yog dab tsi?

Hom Cov Ntaub Ntawv & Kev ntsuas qhov ntsuas: Nominal, Ordinal, Interval thiab Ratio. Hauv kev txheeb cais, muaj plaub cov ntaub ntawv ntsuas ntsuas: nominal, ordinal, interval thiab ratio. Cov no yog txoj hauv kev yooj yim rau sub-categorize ntau hom ntaub ntawv (Ntawm no yog ib qho piv txwv ntawm statistical hom ntaub ntawv ).

Lub hom phiaj ntawm cov ntaub ntawv mining yog dab tsi?

Cov ntaub ntawv mining , kuj hu ua cov ntaub ntawv los yog kev paub nrhiav pom, yog tus txheej txheem ntawm kev txheeb xyuas cov ntaub ntawv thiab hloov nws mus rau hauv kev pom uas qhia txog kev txiav txim siab ua lag luam. Cov ntaub ntawv mining software enables cov koom haum los soj ntsuam cov ntaub ntawv los ntawm ntau qhov chaw txhawm rau txhawm rau txheeb xyuas cov qauv.
