Data preprocessing in Machine Learning yog hais txog cov txheej txheem ntawm kev npaj (ntxuav thiab teeb tsa) cov ntaub ntawv nyoos los ua kom haum rau lub tsev thiab kev cob qhia Machine Learning qauv.
Kev ua ntej txhais li cas hauv kev kawm tshuab?
Cov ntaub ntawv ua ntej yog txheej txheem ntawm kev npaj cov ntaub ntawv nyoos thiab ua kom haum rau lub tshuab kev kawm Nws yog thawj kauj ruam tseem ceeb thaum tsim cov qauv kev kawm tshuab. Thiab thaum ua txhua yam haujlwm nrog cov ntaub ntawv, nws yog qhov yuav tsum tau ntxuav nws thiab muab tso rau hauv ib txoj hauv kev. …
Yuav ua li cas ua ntej hauv tshuab kev kawm thiab vim li cas nws thiaj yuav tsum tau?
Xav tau cov ntaub ntawv ua ntejQee lub tshuab Kev Kawm Txuj Ci xav tau cov ntaub ntawv hauv ib hom ntawv teev tseg, piv txwv li, Random Forest algorithm tsis txhawb qhov tsis muaj nuj nqis, yog li txhawm rau ua tiav random hav zoov algorithm null qhov tseem ceeb yuav tsum tau tswj hwm los ntawm tus thawj raw cov ntaub ntawv teev.
Cov txheej txheem ua ntej yog dab tsi?
Cov txuj ci muab hauv cov ntaub ntawv ua ntej yog dab tsi?
- Data Cleaning/Cleansing. Ntxuav cov ntaub ntawv "dub paug". Cov ntaub ntawv tiag tiag hauv ntiaj teb yuav ua tsis tiav, suab nrov, thiab tsis sib xws. …
- Data Integration. Kev sib xyaw cov ntaub ntawv los ntawm ntau qhov chaw. …
- Data Transformation. Tsim cov ntaub ntawv kub. …
- Kev txo cov ntaub ntawv. Txo qhov sawv cev ntawm cov ntaub ntawv teev.
Yam ua ntej ntawm cov ntaub ntawv piav qhia yog dab tsi?
Cov ntaub ntawv ua ntej yog txheej txheem ntawm kev hloov cov ntaub ntawv nyoos rau hauv hom nkag siab. Nws kuj yog ib kauj ruam tseem ceeb hauv kev tshawb nrhiav cov ntaub ntawv vim peb tsis tuaj yeem ua haujlwm nrog cov ntaub ntawv nyoos. Cov ntaub ntawv zoo yuav tsum raug kuaj ua ntej siv tshuab kev kawm lossis cov ntaub ntawv mining algorithms.

Puas yog tus kws tshaj lij tshuab tshuab kev kawm?
Cov lus pom zoo yog tshuab kev kawm uas pab cov neeg siv pom cov khoom tshiab thiab cov kev pabcuam. Txhua zaus koj mus yuav khoom hauv online, qhov kev pom zoo yog coj koj mus rau cov khoom uas koj yuav tau yuav . Yuav ua li cas hom kev kawm tshuab yog qhov kev pom zoo?
Cov tub ntxhais kawm yuav kawm paub siv lub tshuab ntsuas thiab ncaj?
Nws tau pom tias cov tub ntxhais kawm siv lub ntsuas phoo thiab ncaj ntug ua lej zoo dua thiab khaws cov uas lawv tau kawm. Tsis tas yuav tsum muaj cov tub ntxhais kawm siv lub ntsuas phoo thiab ncaj nraim, thiab tag nrho cov kev tsim kho geometric yuav tsum tau ua los ntawm kev kos duab .
Yuav ua li cas ua ntej cov ntaub ntawv rau kev kawm tshuab?
Muaj xya cov kauj ruam tseem ceeb hauv kev ua cov ntaub ntawv ua ntej hauv Machine Learning: Tau txais cov ntaub ntawv. … Ntawm tag nrho cov tsev qiv ntawv tseem ceeb. … Ntshuam cov ntaub ntawv. … Kev txheeb xyuas thiab tuav cov txiaj ntsig uas ploj lawm.
Kev kawm hauv tsev cuam tshuam li cas rau kev kawm tus kheej?
Raws li peb tau hais los saum no, cov menyuam kawm ntawv hauv tsev yog qhia nws tus kheej ntau, txhais tau tias lawv ua haujlwm ntau ntawm lawv tus kheej lossis nrog cov kws tshaj lij sab nraud hauv tsev. Yeej muaj tseeb tias cov niam txiv tsev kawm ntawv pom lawv cov menyuam ntau dua li cov niam txiv, tab sis qhov zoo!
Yuav ua li cas lej yuav tsum muaj rau kev kawm tshuab?
Kev kawm tshuab yog siv los ntawm plaub lub ntsiab lus tseem ceeb thiab yog Txheeb cais, Linear Algebra, Probability, thiab Calculus. Txawm hais tias cov ntsiab lus txheeb cais yog qhov tseem ceeb ntawm txhua tus qauv, suav nrog pab peb kawm thiab ua kom zoo dua tus qauv .
