Dab tsi yog coding hauv kev tshawb fawb zoo ? Coding yog tus txheej txheem ntawm daim ntawv lo thiab teeb tsa koj zoo cov ntaub ntawv los txheeb xyuas cov ntsiab lus sib txawv thiab kev sib raug zoo ntawm lawv. Thaum twg coding cov lus teb rau cov neeg siv khoom, koj muab cov ntawv sau rau cov lus lossis kab lus uas sawv cev tseem ceeb (thiab rov ua dua) cov ntsiab lus hauv txhua qhov lus teb.
Khaws qhov no hauv kev xav, dab tsi yog txheej txheem coding hauv kev tshawb fawb zoo?
Hauv kev tshawb fawb zoo , coding yog "koj txhais li cas cov ntaub ntawv koj tab tom txheeb xyuas txog" (Gibbs, 2007). Coding yog a txheej txheem ntawm kev txheeb xyuas ib nqe lus hauv cov ntawv nyeem lossis lwm yam khoom siv (daim duab, duab), tshawb nrhiav thiab txheeb xyuas cov ntsiab lus thiab nrhiav kev sib raug zoo ntawm lawv.
5 txoj kev sau cov ntaub ntawv yog dab tsi? Cov txheej txheem sau cov ntaub ntawv zoo
- Open-Ended Surveys thiab Questionnaires. Qhov sib txawv ntawm qhov kaw-kawg yog qhib-kawg kev tshawb fawb thiab cov lus nug.
- 1-on-1 Interviews. Kev xam phaj ib-rau-ib (los yog ntsej muag) yog ib hom kev sau cov ntaub ntawv hauv kev tshawb fawb zoo.
- Focus pawg.
- Kev soj ntsuam ncaj qha.
Ua li no, puas yog coding qualitative lossis quantitative?
Hauv social sciences, coding yog txheej txheem analytical uas cov ntaub ntawv, nyob rau hauv ob qho tib si kom muaj nuj nqis daim ntawv (xws li cov lus nug tshwm sim) los yog zoo daim ntawv (xws li kev xam phaj transcripts) yog categorized los pab kev soj ntsuam. Ib lub hom phiaj ntawm coding yog hloov cov ntaub ntawv mus rau hauv ib daim ntawv uas haum rau computer-pab tsom xam.
Ob hom code yog dab tsi?
Algebraic coding txoj kev xav yeej muab faib ua ob loj hom codes : Linear thaiv cov lej . Convolutional cov lej.
Linear codes
- code lo lus length.
- tag nrho cov lej ntawm cov lus siv tau.
- qhov tsawg kawg nkaus nrug ntawm ob lo lus siv tau, siv feem ntau yog Hamming nrug, qee zaum kuj muaj lwm yam kev ncua xws li Lee nrug.

Puas yog kev tshawb nrhiav linear zoo ib yam li kev tshawb fawb sib txuas?
Chav Kawm: Nrhiav algorithm
Dab tsi yog cov tshuab tshawb nrhiav uas tshawb nrhiav lwm lub tshuab tshawb fawb?
Txhawm rau pib tawm ntawm peb txoj kev tshawb nrhiav taug txuj kev nyuaj, cia saib qee qhov kev tshawb fawb dav dav tshaj qhov peb sab saum toj. DuckDuckGo. Kev txhawj xeeb txog kev ceev ntiag tug hauv online? Nrhiav Encrypt. Nrhiav rau lwm txoj rau DuckDuckGo? Ecosia. Xav tau tsob ntoo cog thaum koj tshawb nrhiav? Dogpile. Blekko. WolframAlpha. Gigablast. Facebook Nrhiav
Selective coding nyob rau hauv kev tshawb fawb yog dab tsi?
Kev xaiv coding yog tus txheej txheem ntawm kev xaiv ib qeb los ua pawg tseem ceeb, thiab hais txog tag nrho lwm pawg rau pawg ntawd. Lub tswv yim tseem ceeb yog los tsim ib zaj dab neeg ib puag ncig uas tag nrho lwm yam yog draped. Muaj kev ntseeg tias lub ntsiab lus tseem ceeb no ib txwm muaj
Dab tsi ntawm cov hauv qab no yog cov txheej txheem kev tshuaj xyuas cov ntaub ntawv hauv kev tshawb fawb zoo?
Cov txheej txheem kev txheeb xyuas cov ntaub ntawv feem ntau siv yog: Kev tsom xam cov ntsiab lus: Qhov no yog ib txoj hauv kev zoo tshaj plaws los tshuaj xyuas cov ntaub ntawv zoo. Kev txheeb xyuas cov lus piav qhia: Txoj kev no yog siv los txheeb xyuas cov ntsiab lus los ntawm ntau qhov chaw, xws li kev xam phaj ntawm cov neeg teb, kev soj ntsuam los ntawm thaj chaw, lossis kev tshawb fawb
Dab tsi yog qhov zoo ntawm kev tshawb fawb zoo tshaj li kev tshawb fawb ntau?
Cov ntaub ntawv los ntawm kev tshawb fawb ntau - xws li kev lag luam loj, pej xeem, thiab cov neeg siv nyiam - muab cov ntaub ntawv tseem ceeb rau kev txiav txim siab ua lag luam. Kev tshawb fawb zoo muab cov ntaub ntawv tseem ceeb rau kev siv hauv kev tsim cov khoom lag luam-nrog rau cov ntaub ntawv hais txog cov neeg siv khoom xav tau, tus qauv coj tus cwj pwm, thiab cov ntaub ntawv siv
