Classification yog ib tug txheej txheem uas peb categorize cov ntaub ntawv mus rau hauv ib tug muab cov chav kawm. Lub hom phiaj tseem ceeb ntawm a kev faib tawm teeb meem yog txhawm rau txheeb xyuas qeb / chav kawm uas cov ntaub ntawv tshiab yuav poob. Classifier : Ib algorithm uas maps cov ntaub ntawv nkag mus rau ib qeb tshwj xeeb.
Ib yam li ntawd ib tug yuav nug, dab tsi yog qhov kev faib algorithms hauv kev kawm tshuab?
Ntawm no peb muaj hom kev faib algorithms hauv Machine Learning:
- Linear Classifiers: Logistic Regression, Naive Bayes Classifier.
- Nyob ze ze.
- Txhawb Vector Machine.
- Ntoo txiav txim siab.
- Tsob Ntoo Boosted.
- Random Hav zoov.
- Neural Networks.
Dhau li saum toj no, dab tsi kev faib algorithm yog raws li qhov tshwm sim? Yam yuav tshwm sim kev faib tawm . Nyob rau hauv tshuab kev kawm, ib tug probabilistic cais cais yog a cais cais uas muaj peev xwm kwv yees, muab kev soj ntsuam ntawm ib qho kev tawm tswv yim, a qhov tshwm sim kev faib tawm ntawm ib pawg ntawm cov chav kawm, tsis yog tsuas yog tso tawm cov chav kawm feem ntau uas qhov kev soj ntsuam yuav tsum yog.
Tsuas yog li ntawd, qhov zoo tshaj plaws kev faib algorithm yog dab tsi?
Random Forest yog ib qho ntawm cov tshuab kawm tau zoo tshaj plaws thiab ntau yam algorithm rau ntau yam ntawm kev faib tawm thiab regression ua hauj lwm, raws li lawv muaj zog ntau rau suab nrov. Nws yog ib qho nyuaj rau tsim ib tug phem random hav zoov.
ML classification yog dab tsi?
Hauv kev kawm tshuab thiab kev txheeb cais, kev faib tawm yog qhov teeb meem ntawm kev txheeb xyuas qhov twg ntawm pawg (sub-populations) qhov kev soj ntsuam tshiab muaj nyob, raws li kev cob qhia cov ntaub ntawv uas muaj cov kev soj ntsuam (lossis cov xwm txheej) uas nws pawg neeg paub.

Puas yog kev tsis ua haujlwm Nagle algorithm muaj kev nyab xeeb?
Puas yog kev cuam tshuam Nagle's algorithm hauv Windows txhawm rau txhim kho Internet ceev kom nyab xeeb? Yog, nws muaj kev nyab xeeb kiag li. Yog tias koj ua raws li txoj cai, koj tuaj yeem lov tes taw thiab pab nws thaum twg koj xav tau
JMeter ua haujlwm li cas rau kev ntsuas kev ua haujlwm?
Nws tuaj yeem siv los txheeb xyuas tag nrho cov server ua haujlwm hauv qab hnyav. JMeter tuaj yeem siv los ntsuas qhov ua tau zoo ntawm ob qho tib si cov peev txheej xws li JavaScript thiab HTML, nrog rau cov peev txheej muaj zog, xws li JSP, Servlets, thiab AJAX. JMeter muab ntau yam kev txheeb xyuas duab ntawm cov ntawv ceeb toom ua haujlwm
Daim ntawv cog lus twg muaj kev ruaj ntseg thiab kev taw qhia kev faib tawm?
GCA muab kev lag luam nrog kev cog lus tshwj xeeb kev nyab xeeb kev qhia kev qhia. GCA muaj txoj cai dav dav txog kev tau txais kev ua haujlwm rau nws lub koom haum, raws li tus thawj coj ntawm lub koom haum
Knn puas yog kev faib algorithm?
KNN algorithm yog ib qho ntawm cov txheej txheem kev faib tawm yooj yim tshaj plaws thiab nws yog ib qho ntawm cov kev kawm siv ntau tshaj plaws. KNN yog qhov tsis yog parametric, tub nkeeg kawm algorithm. Nws lub hom phiaj yog siv cov ntaub ntawv database uas cov ntsiab lus cov ntaub ntawv tau muab cais ua ob peb chav kawm los kwv yees qhov kev faib tawm ntawm cov qauv tshiab
Dab tsi yog qhov tsis sib thooj nco kev faib hauv kev ua haujlwm?
Kev faib cov cim xeeb tsis sib thooj tso cai rau cov txheej txheem kom tau txais ntau lub cim xeeb thaiv ntawm qhov chaw sib txawv hauv lub cim xeeb raws li nws qhov yuav tsum tau ua. Lub cim xeeb tsis sib thooj kuj tseem txo cov kev nco khib nyiab vim yog sab hauv thiab sab nrauv fragmentation
