Normalization muaj txiaj ntsig thaum koj cov ntaub ntawv muaj qhov sib txawv thiab cov algorithm koj siv tsis ua kev xav txog kev faib koj cov ntaub ntawv, xws li cov neeg nyob ze ze tshaj plaws thiab cov khoom siv neural. tes hauj lwm. Standardization xav tias koj cov ntaub ntawv muaj Gaussian (tws nkhaus) faib.
Thaum twg peb yuav tsum normalize cov ntaub ntawv?
Cov ntaub ntawv yuav tsum tau ua raws li tus qauv lossis tus qauv kom coj tag nrho cov kev hloov pauv rau hauv kev faib ua ke. Piv txwv li, yog tias ib qho kev sib txawv yog 100 lub sij hawm loj dua lwm qhov (qhov nruab nrab), ces koj tus qauv yuav coj tus cwj pwm zoo dua yog tias koj normalize / standardize ob qhov sib txawv kom sib npaug.
Dab tsi yog qhov txawv ntawm normalization thiab standardization?
Normalization feem ntau txhais tau hais tias rov ntsuas qhov muaj nuj nqis rau hauv qhov ntau ntawm [0, 1]. Standardization feem ntau txhais tau tias rescales cov ntaub ntawv kom muaj ib tug txhais tau tias ntawm 0 thiab tus qauv sib txawv ntawm 1 (unit variance).
Thaum twg thiab vim li cas peb thiaj xav tau cov ntaub ntawv normalization?
Nyob hauv cov ntsiab lus yooj yim, normalization ua kom tag nrho koj cov ntaub ntawv zoo li thiab nyeem tib txoj kev hla txhua cov ntaub ntawv. Normalization yuav standardize teb nrog rau lub tuam txhab npe, hu rau npe, URLs, chaw nyob cov ntaub ntawv (txoj kev, xeev thiab nroog), xov tooj thiab lub npe txoj hauj lwm.
Koj xaiv qhov normalization thiab standardization li cas?
Nyob hauv lub ntiaj teb kev lag luam, "kev ua kom zoo li qub" feem ntau txhais tau tias qhov ntau ntawm qhov muaj nuj nqis"normalized to be from 0.0 to 1.0". "Standardization" feem ntau txhais tau hais tias qhov ntau ntawm qhov tseem ceeb yog "tus qauv" los ntsuas seb muaj pes tsawg tus qauv sib txawv tus nqi yog los ntawm nws qhov txhais tau tias.
