Hauv kev saib xyuas kev kawm kev siv hauv tshuab kev kawm thiab txheeb cais kev kawm txoj kev xav, generalization yuam kev (tseem hu ua tus qauv tawm yuam kev ) yog ib qho kev ntsuas ntawm qhov tseeb npaum li cas lub algorithm tuaj yeem kwv yees qhov txiaj ntsig ntawm cov ntaub ntawv yav dhau los tsis pom.

Yog li ntawd, dab tsi yog hom kev ua yuam kev hauv kev kawm tshuab?

Rau cov teeb meem kev faib binary, muaj ob lub hauv paus hom kev ua yuam kev . Hom 1 yuam kev (false positives) thiab Hom 2 yuam kev (cov tsis ntseeg cuav). Nws yog feem ntau ua tau los ntawm kev xaiv tus qauv thiab kho kom nce ib qho thaum txo qis, thiab feem ntau ib tus yuav tsum xaiv qhov twg yam yuam kev tau txais ntau dua.

Kuj Paub, Dab tsi yog Overfitting hauv kev kawm tshuab? Overfitting hauv Machine Learning Overfitting hais txog tus qauv uas ua qauv qhia cov ntaub ntawv qhia zoo heev. Overfitting tshwm sim thaum tus qauv kawm paub cov ntsiab lus thiab suab nrov hauv cov ntaub ntawv qhia txog qhov uas nws cuam tshuam qhov kev ua tau zoo ntawm tus qauv ntawm cov ntaub ntawv tshiab.

Kuj nug, dab tsi yog qhov kev ua haujlwm dav dav?

Cov generalization kev ua tau zoo ntawm kev kawm algorithm hais txog qhov kev ua tau zoo ntawm cov ntaub ntawv tawm ntawm cov qauv ntawm cov qauv kawm los ntawm algorithm.

Classification yuam kev yog dab tsi?

Kev faib ua yuam kev . Cov kev faib ua yuam kev Ei ntawm ib qho kev pab cuam ib tus neeg kuv nyob ntawm tus naj npawb ntawm cov qauv tsis raug muab cais tawm (qhov tsis zoo thiab qhov tsis zoo) thiab raug ntsuas los ntawm cov qauv: qhov twg f yog tus lej ntawm cov qauv kuaj tsis raug, thiab n yog tag nrho cov qauv kuaj.
