Qee qhov piv txwv nrov ntawm saib xyuas tshuab kawm algorithms yog: Linear regression rau cov teeb meem regression. Random hav zoov rau kev faib tawm thiab cov teeb meem regression. Txhawb vector tshuab rau kev faib cov teeb meem.
Tsis tas li ntawd, dab tsi yog kev saib xyuas kev kawm algorithm?
Saib xyuas kev kawm yog cov tshuab kev kawm hauj lwm ntawm kev kawm muaj nuj nqi uas maps ib input rau ib qhov tso zis raws li piv txwv input-output khub. A saib xyuas kev kawm algorithm tsom xam cov kev cob qhia cov ntaub ntawv thiab tsim ib qho kev ua haujlwm inferred, uas tuaj yeem siv los ua cov piv txwv tshiab.
Dhau li saum toj no, dab tsi yog tus saib xyuas thiab tsis saib xyuas algorithm? Hauv ib saib xyuas kev kawm qauv, lub algorithm kawm ntawm ib daim ntawv teev cov ntaub ntawv, muab cov lus teb tseem ceeb uas tus algorithm tuaj yeem siv los ntsuas nws qhov tseeb ntawm cov ntaub ntawv kev cob qhia. Ib tsis saib xyuas qauv, nyob rau hauv sib piv, muab unlabeled cov ntaub ntawv uas tus algorithm sim ua kom nkag siab los ntawm kev rho tawm cov yam ntxwv thiab cov qauv ntawm nws tus kheej.
Tsis tas li ntawd, txhua hom kev saib xyuas kev kawm yog dab tsi?
Muaj ob hom kev kawm saib xyuas Cov txheej txheem: Regression thiab Classification. Kev faib tawm cais cov ntaub ntawv, Regression haum cov ntaub ntawv.
Puas yog Machine Learning yog hom algorithm?
Nws yog pom raws li ib tug subset ntawm artificial txawj ntse. Tshuab kawm algorithms tsim kom muaj tus qauv lej raws li cov qauv ntaub ntawv, hu ua "cov ntaub ntawv qhia kev kawm", txhawm rau ua qhov kev twv lossis kev txiav txim siab yam tsis tau piav qhia meej los ua haujlwm.

Dab tsi yog kev saib xyuas kev kho mob thiab kev kho kom zoo dua qub?
Kev piav qhia ntxaws ntxaws yog qhov txheej txheem nco uas suav nrog kev xav txog lub ntsiab lus ntawm lub ntsiab lus uas yuav tsum nco ntsoov, sib piv nrog cov txheej txheem ntawm kev rov hais dua cov lus rau tus kheej ntau dua. Kev saib xyuas kev kho mob yog cov txheej txheem ntawm kev rov xav txog lossis hais lus ib yam ntawm cov ntaub ntawv
Puas yog Lstm saib xyuas lossis tsis saib xyuas?
Lawv yog ib txoj kev kawm uas tsis muaj kev saib xyuas, txawm li cas los xij, lawv raug cob qhia siv cov kev kawm saib xyuas, hu ua tus saib xyuas tus kheej. Lawv feem ntau raug cob qhia ua ib feem ntawm cov qauv dav dav uas sim ua kom rov tsim cov tswv yim
Dab tsi yog kev saib xyuas thiab tsis saib xyuas kev kawm algorithms?
Saib xyuas: Tag nrho cov ntaub ntawv tau sau npe thiab cov algorithms kawm los kwv yees cov txiaj ntsig ntawm cov ntaub ntawv nkag. Unsupervised: Tag nrho cov ntaub ntawv yog unlabeled thiab cov algorithms kawm rau inherent qauv los ntawm cov ntaub ntawv input
