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.
