Kev kawm tsis saib xyuas yog a tshuab kev kawm txheej txheem, qhov twg koj tsis tas yuav saib xyuas tus qauv. Unsupervised machine learning pab koj nrhiav txhua yam tsis paub cov qauv hauv cov ntaub ntawv. Clustering thiab Association yog ob hom Kev kawm tsis saib xyuas.
Hais txog qhov no, Machine Learning puas tau saib xyuas lossis tsis saib xyuas?
Nyob rau hauv lub teb ntawm tshuab kev kawm , muaj ob hom haujlwm tseem ceeb: saib xyuas , thiab tsis saib xyuas . Qhov sib txawv tseem ceeb ntawm ob hom yog qhov ntawd saib xyuas kev kawm yog ua tiav siv qhov tseeb hauv av, lossis hauv lwm lo lus, peb muaj kev paub ua ntej ntawm qhov txiaj ntsig ntawm cov khoom siv rau peb cov qauv yuav tsum yog.
Qhov thib ob, qhov kev kawm tsis saib xyuas siv nyob qhov twg? Kev kawm tsis saib xyuas feem ntau yog siv ua ntej cov ntaub ntawv. Feem ntau, qhov ntawd txhais tau hais tias compressing nws nyob rau hauv qee lub ntsiab lus khaws cia zoo li nrog PCA lossis SVD ua ntej pub nws mus rau qhov sib sib zog nqus neural net lossis lwm tus saib xyuas. kev kawm algorithm.
Qhov thib ob, qhov piv txwv kev kawm uas tsis saib xyuas yog dab tsi?
Ntawm no tuaj yeem ua tau unsupervised machine learning piv txwv zoo li k Ua pawg , Hidden Markov Model, DBSCAN Ua pawg , PCA, t-SNE, SVD, Association rule. Cia wb mus saib ob peb yam ntawm lawv: k-txhais tau tias Ua pawg - Cov ntaub ntawv mining. k- lus pawg yog lub hauv paus algorithm hauv unsupervised machine learning kev ua haujlwm.
Kev kawm uas tsis saib xyuas yog dab tsi muab piv txwv ntawm cov haujlwm uas tsis muaj kev saib xyuas?
Ib txhia nrov piv txwv ntawm kev kawm tsis muaj kev saib xyuas algorithms yog: k-txhais tau rau pawg teeb meem. Apriori algorithm rau txoj cai koom haum kev kawm teeb meem.

Dab tsi yog kev saib xyuas tsis raug cai hauv lub xeev kev zam hauv Java?
Raws li tau piav qhia los ntawm cov ntaub ntawv raug cai, IllegalMonitorStateException tuaj yeem tshwm sim thaum cov xov sim tos ntawm cov khoom saib, lossis ceeb toom rau lwm cov xov tos rau cov khoom hais tias, thaum xov tsis muaj tus saib hauv nqe lus nug. Muab lwm txoj kev, yog Lub Object
Dab tsi yog qhov txawv ntawm kev sib raug zoo unary kev sib raug zoo binary thiab kev sib raug zoo ternary?
Kev sib raug zoo tsis sib xws yog thaum ob tus neeg koom hauv kev sib raug zoo yog tib lub koom haum. Piv txwv li: Cov ncauj lus yuav yog qhov yuav tsum tau ua ua ntej rau lwm yam kev kawm. Kev sib raug zoo ternary yog thaum peb lub koom haum koom nrog kev sib raug zoo
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
Lub koom haum hauv kev kawm tsis muaj kev saib xyuas yog dab tsi?
Koom haum cov cai lossis kev txheeb xyuas koom haum kuj yog ib lub ntsiab lus tseem ceeb hauv kev tshawb nrhiav cov ntaub ntawv. Qhov no yog ib txoj kev tsis saib xyuas, yog li peb pib nrog cov ntaub ntawv tsis muaj npe. Cov ntaub ntawv tsis muaj npe yog cov ntaub ntawv tsis muaj qhov sib txawv uas muab cov lus teb raug rau peb. Kev txheeb xyuas lub koom haum sim nrhiav kev sib raug zoo ntawm cov koom haum sib txawv
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
