Fuzzy Logic vs Neural Network
Fuzzy Logic belongs rau tsev neeg ntawm ntau qhov laj thawj. Nws tsom ntsoov rau qhov ruaj khov thiab kwv yees qhov kev xav tsis sib haum rau qhov tseeb thiab qhov tseeb. Ib qho kev sib txawv hauv fuzzy logic tuaj yeem coj qhov tseeb tus nqi nruab nrab ntawm 0 thiab 1, as opposed to take true or false in traditional binary sets. Neural networks (NN) lossis cov khoom siv hluav taws xob neural (ANN) yog cov qauv kev suav uas yog tsim los ntawm kev sib txuas ntawm cov paj hlwb. Ib qho ANN yog tsim los ntawm cov neurons dag uas txuas nrog ib leeg. Feem ntau, ANN hloov kho nws cov qauv raws li cov ntaub ntawv tuaj rau nws.

Fuzzy Logic belongs rau tsev neeg ntawm ntau qhov laj thawj. Nws tsom ntsoov rau qhov ruaj khov thiab kwv yees qhov kev xav tsis sib haum rau qhov tseeb thiab qhov tseeb. Ib qho kev sib txawv hauv fuzzy logic tuaj yeem coj qhov tseeb tus nqi nruab nrab ntawm 0 thiab 1, as opposed to take true or false in traditional binary sets. Txij li qhov tseeb tus nqi yog qhov ntau, nws tuaj yeem tswj qhov tseeb ib nrab. Pib ntawm fuzzy logic tau cim nyob rau hauv 1956, nrog rau kev taw qhia ntawm fuzzy teeb txoj kev xav los ntawm Lotfi Zadeh. Fuzzy logic muab ib txoj hauv kev los txiav txim siab meej raws li cov ntaub ntawv tsis meej thiab tsis meej pem. Fuzzy logic yog siv dav rau cov ntawv thov hauv kev tswj hwm, vim nws zoo ib yam li tib neeg txiav txim siab tab sis sai dua. Fuzzy logic tuaj yeem muab tso rau hauv kev tswj hwm raws li cov khoom siv me me rau cov chaw ua haujlwm PC loj.
Neural Networks yog dab tsi?
ANN yog tus qauv kev suav uas tsim los ntawm cov kab ke lom neeg tsis zoo. Ib qho ANN yog tsim los ntawm cov neurons dag uas txuas nrog ib leeg. Feem ntau, ANN hloov kho nws cov qauv raws li cov ntaub ntawv tuaj rau nws. Ib txheej txheej txheej txheej hu ua cov cai kawm yuav tsum tau ua raws li thaum tsim ANN. Tsis tas li ntawd, cov txheej txheem kev kawm yuav tsum tau kawm cov ntaub ntawv los tshawb pom qhov ua haujlwm zoo tshaj plaws ntawm ANN. ANNs tuaj yeem siv los kawm txog kev ua haujlwm kwv yees rau qee cov ntaub ntawv pom. Tab sis thaum thov ANN, muaj ntau yam uas yuav tsum tau xav txog. Tus qauv yuav tsum tau ua tib zoo xaiv nyob ntawm cov ntaub ntawv. Kev siv cov qauv tsis tsim nyog yuav ua rau txoj kev kawm nyuaj. Xaiv qhov kev kawm algorithm yog qhov tseem ceeb, vim qee qhov kev kawm algorithms ua tau zoo dua nrog qee hom ntaub ntawv.
Qhov txawv ntawm Fuzzy Logic thiab Neural Networks yog dab tsi?
Fuzzy logic tso cai rau kev txiav txim siab raws li cov ntaub ntawv tsis tseeb lossis tsis meej, qhov ANN sim muab cov txheej txheem kev xav ntawm tib neeg los daws cov teeb meem yam tsis muaj lej ua qauv rau lawv. Txawm hais tias ob qho tib si ntawm cov txheej txheem no tuaj yeem siv los daws cov teeb meem nonlinear, thiab cov teeb meem uas tsis raug teev tseg, lawv tsis muaj feem cuam tshuam. Hauv kev sib piv rau Fuzzy logic, ANN sim siv cov txheej txheem kev xav hauv tib neeg lub hlwb los daws cov teeb meem. Ntxiv mus, ANN suav nrog cov txheej txheem kev kawm uas suav nrog kev kawm algorithms thiab xav tau cov ntaub ntawv kawm. Tab sis muaj hybrid txawj ntse tshuab tsim siv ob txoj kev hu ua Fuzzy Neural Network (FNN) los yog Neuro-Fuzzy System (NFS).
