Saib xyuas : Tag nrho cov ntaub ntawv sau npe thiab cov algorithms kawm los kwv yees cov zis los ntawm cov ntaub ntawv nkag. Tsis saib xyuas : Tag nrho cov ntaub ntawv yog unlabeled thiab cov algorithms kawm mus rau inherent qauv los ntawm cov ntaub ntawv input.

Ntawm no, qhov txawv ntawm kev saib xyuas thiab tsis saib xyuas kev kawm algorithms yog dab tsi?

Saib xyuas kev kawm yog cov txheej txheem ntawm kev ua tiav ib txoj hauj lwm los ntawm kev muab kev cob qhia , input thiab output qauv rau cov systems whereas tsis saib xyuas kev kawm yog tus kheej- kev kawm txheej txheem nyob rau hauv uas system yuav tsum nrhiav tau cov yam ntxwv ntawm cov input pej xeem los ntawm nws tus kheej thiab tsis muaj cov txheej txheem ua ntej siv.

Dab tsi yog kev saib xyuas tsis saib xyuas thiab kev txhawb nqa kev kawm? Nyob rau hauv ib tug nutshell, saib xyuas kev kawm yog thaum tus qauv kawm los ntawm ib daim ntawv teev cov ntaub ntawv nrog kev taw qhia. Thiab, tsis saib xyuas kev kawm yog qhov twg tshuab yog muab kev cob qhia raws li cov ntaub ntawv tsis muaj npe tsis muaj kev taw qhia.

Tsis tas li ntawd, kev saib xyuas thiab tsis saib xyuas kev kawm nrog piv txwv li cas?

Hauv Saib xyuas kev kawm , koj cob qhia tshuab siv cov ntaub ntawv uas zoo "labeled." Rau piv txwv , Tus me nyuam tuaj yeem txheeb xyuas lwm tus dev raws li yav dhau los saib xyuas kev kawm . Regression thiab Kev faib tawm yog ob hom saib xyuas tshuab kev kawm cov txheej txheem. Ua pawg thiab Association yog ob hom Kev kawm tsis saib xyuas.

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.
