Txhais ntawm cais cais . 1: ib qho uas qhia tshwj xeeb: lub tshuab rau kev txheeb xyuas cov ntsiab lus ntawm cov khoom (xws li ore) 2: lo lus lossis morpheme siv nrog cov lej lossis nrog cov npe tsim cov khoom suav tau lossis ntsuas tau.
Ib yam li ntawd, tus classifier ua li cas?
Ib tug classifier yog ib tug hypothesis los yog discrete-valued muaj nuj nqi uas yog siv los muab (categorical) cov ntawv sau rau cov ntaub ntawv tshwj xeeb. Hauv kev faib email piv txwv, tus qauv no tuaj yeem yog qhov kev xav rau kev sau npe email ua spam lossis tsis yog spam.
Ib yam li ntawd, tus qauv classifier yog dab tsi? Classifier : Ib qho algorithm uas qhia cov ntaub ntawv nkag mus rau ib pawg tshwj xeeb. Kev faib ua qauv : A kev faib ua qauv sim kos ib co lus xaus los ntawm cov tswv yim muaj nuj nqis muab rau kev cob qhia. Nws yuav kwv yees cov ntawv teev npe / pawg rau cov ntaub ntawv tshiab.
Ib yam li ntawd ib tug yuav nug, leej twg hu ua classifier?
A cais cais (abbreviated clf los yog cl) yog ib lo lus los yog affix uas nrog rau cov npe thiab tuaj yeem txiav txim siab "qib" tus npe nyob ntawm seb hom nws tus neeg xa mus. Suav cov cais kuj feem ntau hu ua ntsuas cov lus, txawm tias qee tus kws sau ntawv ua qhov sib txawv ntawm ob nqe lus.
Vim li cas peb thiaj siv classifiers?
A cais cais siv qee cov ntaub ntawv kev cob qhia kom nkag siab txog qhov muab cov tswv yim sib txawv li cas cuam tshuam rau chav kawm. Thaum lub classifier yog cob qhia kom raug, nws tuaj yeem ua tau siv txhawm rau txheeb xyuas tus email tsis paub. Kev faib tawm yog nyob rau hauv qeb ntawm kev saib xyuas kev kawm qhov twg lub hom phiaj tseem muab nrog cov ntaub ntawv nkag.
