A Convolutional Neural Network (ConvNet/CNN) yog aDeep Learning algorithm uas tuaj yeem coj hauv cov duab nkag, qhov tseem ceeb (kawm qhov hnyav thiab kev tsis ncaj ncees) rau ntau yam / khoom hauv daim duab thiab tuaj yeem sib txawv ntawm ib leeg.
Tsis tas li lo lus nug yog, dab tsi yog qhov kev sib txuas ntawm neural network zoo rau?
Qhov no yog lub tswv yim tom qab siv cov pooling hauv convolutional neural networks . Lub pas dej txheej ua hauj lwm kom nce zuj zus txo qhov loj me me ntawm qhov kev nthuav qhia, kom txo tau tus naj npawb ntawm cov tsis, memoryfootprint thiab tus nqi ntawm kev suav hauv network , thiab thiaj li yuav tswj tau overfitting.
Tsis tas li ntawd, cov ntxaij lim dej hauv convolutional neural networks yog dab tsi? Hauv convolutional ( lim thiab encodingby transformation) neural networks (CNN) txhua network txheej ua raws li kev tshawb nrhiav lim rau qhov muaj cov yam ntxwv tshwj xeeb lossis cov qauv muaj nyob hauv cov ntaub ntawv qub.
Kuj Paub, CNN kawm li cas?
Vim lub CNN saib ntawm pixels hauv cov ntsiab lus, nws yog muaj peev xwm kawm cov qauv thiab cov khoom thiab lees paub txawm tias lawv yog nyob rau hauv ntau txoj hauj lwm ntawm daim duab. CNNs (convolutional txheej yuav tsum tau tshwj xeeb) kawm thiaj li hu uafilters lossis kernels (qee zaum kuj hu ua filterkernels).
Lub hom phiaj ntawm convolution txheej yog dab tsi?
Qhov tseem ceeb Lub hom phiaj ntawm Convolution nyob rau hauv cov ntaub ntawv ntawm aConvNet yog rho tawm cov yam ntxwv los ntawm cov duab input. Convolution khaws cov kev sib raug zoo ntawm cov pixels los ntawm kev kawm cov duab uas siv cov squares me me ntawm inputdata.

Dab tsi yog txhais los ntawm wireless sensor networks?
Wireless Sensor Networks. WSN yog lub wireless network uas muaj cov chaw nres tsheb hauv paus thiab cov lej ntawm cov nodes (wireless sensors). Cov tes hauj lwm no yog siv los saib xyuas lub cev lossis ib puag ncig ib puag ncig xws li suab, siab, kub thiab sib koom ua ke dhau cov ntaub ntawv los ntawm lub network mus rau qhov chaw tseem ceeb raws li qhia hauv daim duab
Vim li cas neural networks muaj ntau txheej?
Vim li cas peb thiaj muaj ntau cov khaubncaws sab nraud povtseg thiab ntau qhov ntawm ib txheej hauv ib lub neural network? Peb xav tau yam tsawg kawg ib txheej zais nrog cov tsis-linear activation kom muaj peev xwm kawm tsis-linear functions. Feem ntau, ib tug xav txog txhua txheej raws li qib abstraction. Li no koj tso cai rau tus qauv kom haum ntau txoj haujlwm
Lub neural network ua haujlwm yooj yim li cas?
Lub tswv yim tseem ceeb tom qab lub network neural isto simulate (daim ntawv theej hauv txoj kev yooj yim tab sis muaj kev ntseeg ncaj ncees) ntau ntau cov hlwb sib txuas hauv lub computer kom koj tuaj yeem tau txais nws los kawm yam, paub txog cov qauv, thiab kev txiav txim siab hauv tib neeg txoj kev. Tab sis nws tsis yog lub hlwb
Multiplexing yog dab tsi thiab nws hom hauv computer networks?
Feem ntau muaj ob hom multiplexers, uas yog analog thiab digital. Lawv tau muab faib ua ntau zaus Division Multiplexing (FDM), Wavelength Division Multiplexing (WDM), thiab Time Division Multiplexing (TDM). Cov duab hauv qab no muab cov lus qhia ntxaws txog qhov kev faib tawm no
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
