Cov yooj yim kev xav qab a neural network yog simulate (copy hauv ib qho yooj yim tab sis muaj kev ntseeg ncaj ncees) ntau ntau cov hlwb sib cuam tshuam hauv lub computer kom koj ua tau kom nws kawm tej yam, paub txog cov qauv, thiab txiav txim siab raws li tib neeg txoj kev. Tab sis nws tsis yog lub hlwb.
Tsis tas li ntawd, neural network ua haujlwm li cas?
Neural nets yog ib tug txhais tau tias ntawm kev ua machinelearning, nyob rau hauv uas lub computer kawm ua ib co hauj lwm byanalyzing kev cob qhia piv txwv. Ua qauv xoob ntawm tib neeg lub hlwb, a neural xov muaj ntau txhiab lossis ntau lab ntawm cov txheej txheem ua haujlwm yooj yim uas muaj kev sib cuam tshuam zoo.
Ib yam li ntawd, qhov yooj yim neural network yog dab tsi? Qhov piav qhia ntawm no yog hu ua Perceptron thiab yog thawj neural network puas tau tsim. Nws muaj nyob rau ntawm 2 neurons nyob rau hauv kab ntawv thiab 1 neuron nyob rau hauv lub outputcolumn.
Qhov thib ob, neural network yog dab tsi hauv cov lus yooj yim?
A neural network yog ib tug series ntawm algorithms uas endeavors kom paub txog kev sib raug zoo nyob rau hauv ib tug txheej ntawm datathrough ib tug txheej txheem uas ua raws li txoj kev uas tib neeg lub hlwb ua hauj lwm. Neural networks tuaj yeem hloov pauv hloov cov tswv yim; yog li cov network tsim cov txiaj ntsig zoo tshaj plaws yam tsis tas yuav rov tsim cov qauv tsim tawm.
Dab tsi yog cov tswv yim rau neural network?
Cov nkag txheej a neural network yog tsim los ntawm cov khoom siv dag zog nkag neurons, thiab nqa cov ntaub ntawv pib rau hauv lub cev rau kev ua haujlwm ntxiv los ntawm cov txheej txheem tom ntej ntawm cov paj hlwb. Cov nkag txheej yog qhov pib ntawm kev ua haujlwm rau cov khoom siv dag zog neural network.

Dab tsi yog theem plaub hauv cov kauj ruam yooj yim rau kev siv lub tshuab virtual hauv Azure?
Kauj ruam 1 - Nkag mus rau Azure Management Portal. Kauj ruam 2 - Nyob rau sab laug vaj huam sib luag nrhiav thiab nyem rau ntawm 'Virtual Machines'. Tom qab ntawd nyem rau ntawm 'Create a Virtual Machine'. Kauj ruam 3 - Los yog nyem 'Tshiab' nyob rau hauv qab sab laug ces kaum
Dab tsi yog cov ntaub ntawv yooj yim tsim los ua thiab nws ua tiav cov haujlwm no li cas?
Lub hom phiaj tseem ceeb tshaj plaws ntawm cov ntaub ntawv kaw lus yog tswj cov neeg siv cov ntaub ntawv. Qhov no suav nrog khaws cia, rov qab thiab kho cov ntaub ntawv. Qee lub tshuab ua ntaub ntawv lees txais cov ntaub ntawv khaws cia raws li cov kwj ntawm bytes uas tau sau thiab khaws cia kom zoo rau kev tshaj tawm
Yuav ua li cas koj ua ib qho yooj yim cardboard lub koob yees duab?
Qhov Koj Yuav Ua Li Cas Txiav 2-nti ntu ntawm lub raj xaim thiab muab lo rau hauv nruab nrab ntawm lub thawv kom ua lub koob yees duab lens. Npog lub koob yees duab thiab lub koob yees duab lens nrog washitape. Txiav ib lub qhov me me saum lub lens rau pem hauv ntej ntawm lub thawv. Daim kab xev yas qhwv hla ob lub qhov los npog
Dab tsi software tswj lub computer cov haujlwm yooj yim?
Qhov yooj yim nkag / tso zis system (BIOS) tswj cov haujlwm yooj yim tshaj plaws ntawm lub khoos phis tawj thiab ua qhov ntsuas tus kheej txhua zaus koj tig nws
Yuav ua li cas pub rau neural network ua haujlwm?
Lub feedforward neural network yog thawj thiab yooj yim tshaj plaws ntawm cov khoom siv neural network tsim. Hauv lub network no, cov ntaub ntawv txav mus rau hauv ib qho kev taw qhia nkaus xwb, rau pem hauv ntej, los ntawm cov tswv yim ntawm cov tswv yim, los ntawm cov nodes zais (yog tias muaj) thiab mus rau cov zis tawm. Tsis muaj lub voj voog lossis voj voog hauv lub network
