Ntau qhov kev vam meej ntawm tshuab kev kawm yog qhov ua tiav hauv engineering yam ntxwv uas tus neeg kawm tuaj yeem nkag siab. Feature engineering yog tus txheej txheem ntawm kev hloov cov ntaub ntawv nyoos rau hauv cov yam ntxwv uas zoo dua sawv cev rau qhov teeb meem hauv qab rau cov qauv kev kwv yees, ua rau cov qauv zoo dua qub ntawm cov ntaub ntawv tsis pom.

Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog cov yam ntxwv hauv kev kawm tshuab?

Hauv tshuab kev kawm thiab qauv paub, a feature yog ib tug tib neeg ntsuas cov cuab yeej los yog tus yam ntxwv ntawm ib tug phenomenon raug soj ntsuam. Xaiv cov ntaub ntawv, kev ntxub ntxaug thiab ywj siab nta yog ib kauj ruam tseem ceeb rau kev ua tau zoo algorithms nyob rau hauv cov qauv kev paub, kev faib thiab regression.

Ib sab saum toj, dab tsi yog qhov piv txwv hauv kev kawm tshuab? Piv txwv : Ib piv txwv yog ib qho piv txwv hauv cov ntaub ntawv kev cob qhia. Ib piv txwv tau piav qhia los ntawm ntau tus cwj pwm. Ib tus cwj pwm tuaj yeem yog daim ntawv teev npe. Attribute/Feature: Ib qho attribute yog ib yam ntawm ib piv txwv (e.g. kub, humidity). Cov cwj pwm feem ntau hu ua nta hauv Machine Learning.

Dhau li ntawm no, cov ntaub ntawv Featurization yog dab tsi?

Nyob rau hauv tag nrho cov no, tej zaum koj yuav wondering dab tsi tiag tiag kev ua yeeb yam yog. Ua kom yooj yim, nws yog txheej txheem uas hloov cov khoom zes JSON rau hauv tus taw tes. Nws dhau los ua vector ntawm scalar tus nqi uas yog qhov yuav tsum tau ua hauv cov txheej txheem tshuaj xyuas.

AutoML ua dab tsi?

Automated machine learning, los yog AutoML , lub hom phiaj txo lossis tshem tawm qhov xav tau rau cov kws tshaj lij cov ntaub ntawv tshawb fawb los tsim cov tshuab kev kawm thiab cov qauv kev kawm tob. Es tsis txhob, ib AutoML system tso cai rau koj los muab cov ntaub ntawv qhia cov ntawv sau ua cov tswv yim thiab tau txais cov qauv ua kom zoo raws li cov zis.
