Shabakadda Jidadka Wayn oo ka gudub Xidhiidhada
Isku xidhka ka bood waxa ay macluumaadka u saamaxaysaa in ay ka boodaan lakabyada hore, iyo shabakadaha jidadku waxa ay ahaayeen nooca hore ee fikirkan.

They solve the problem of training very deep networks, which paved the way for ResNets and modern deep learning.
quusid qoto dheer
Kahor inta aan la boodin isku xirka, isku dhafka lakabyo badan ayaa ka dhigtay shabakadaha mid adag, ma fiicna, in la tababaro sababtoo ah gradients ayaa meesha ka baxay iyo calaamadaha hoos u dhacay. Shabakadaha wadooyinka, oo la soo bandhigay 2015, ayaa lagu daray albaabo la bartay kuwaas oo koontaroolaya inta ka mid ah gelinta lakabka ayaa loo beddelaa si toos ah loo dhex maro, oo ay dhiirigelisay gating LSTM. Wax yar ka dib, ResNets ayaa tan u fududaysay isku xidhka hadhaaga ah, halkaas oo lakabku barto shaqada hadhaaga ah oo wax soo saarkiisa lagu daro gelinta iyada oo loo marayo marin-gaab aqoonsi. Jidadka gaagaaban waxay u abuuraan wadooyin toos ah oo gradients si ay gadaal ugu socdaan, taasoo suurtogal ka dhigaysa in la tababaro shabakadaha boqolaal ama xitaa kun lakab oo qoto dheer. Isku xirka bood ayaa hadda ka muuqda meel walba, oo ay ku jiraan U-Nets, DeenseNets, iyo transformers.
Aragtida Farsamada
Qalabka haraaga ah wuxuu xisaabiyaa wax soo saarka = F(x) + x, markaa shabakadu waxay u baahan tahay kaliya inay barato haraaga F(x) halkii ay ka baran lahayd khariidad buuxda. Inta lagu jiro dib-u-faafinta ereyga aqoonsiga wax-ku-darku wuxuu maraa jaangooyooyin aan isbeddelin, oo dhinac ka leexanaya jaangooyooyin lumaya. Shabakadda wadooyinku waxay tan ku soo koobaan beddelka gate T oo waxay qaadaan albaabka, wax soo saarka = F(x)*T(x) + x*(1 - T(x)), halkaasoo T lagu barto oo u dhexeeya 0 iyo 1.
Saamaynta Istiraatijiyadeed
Qiimaha iyo miisaaniyada
Go'aamada qaab-dhismeedku waxay horseedaan waxqabadka iyo kharashka hawlgalka sannadaha.
Go'aamo cad
Waxbarashada farsamada waxay ka caawisaa kooxaha inay doortaan xidhmo sax ah, ma aha oo kaliya kan ugu cusub.
Xakamaynta tayada
Doorashooyinka injineernimada ee wanaagsan waxay yareeyaan shilalka la isku halleyn karo ee wax soo saarka.
Mustaqbalka Shabakadda Waddooyinka iyo Ka Boodo Isku-xidhka
Isku xirka boodboodku hadda waa dhisme aan caadi ahayn halkii ay ka ahaan lahaayeen khiyaamo ikhtiyaari ah. Transformer kastaa waxa uu isticmaalaa isku xidhka hadhaaga ah ee ku wareegsan dareenkiisa iyo horudhac-siiyeyaal-hoosaadyada, waxayna weli lama huraan u yihiin moodooyinka fidinta, qaybaha U-Nets, iyo shabakadaha garaafyada. Cilmi baaristu waxay sahamisaa meelaynta caadiga ah ee ka wanaagsan, cabirka la baran karo ee waddooyinka haraaga ah, iyo qaab dhismeedka dib loo rogi karo ee dib u xisaabiya hawlgelinta si loo badbaadiyo xusuusta. Fikradda udub-dhexaadka ah ee ilaalinta calaamadda qoto dheer waxay sii jiri doontaa marka moodooyinka koraan.
Dhaqangelinta Adduunka-dhabta ah
ResNet-50 iyo ResNet-152 waxay adeegsadaan hadhaaga gaagaaban si ay u tababaraan kala soocida sawirada aadka u qoto dheer
Transformers iyo moodooyinka luqadaha waaweyn waxay ku duubaan isku xirnaanta hadhaaga ah ee dareenka iyo lakabyada quudinta
Xidhiidhada boodboodka ee U-Net waxay ka gudbaan tafaasiisha meel wanaagsan laga bilaabo codeeyaha ilaa codeeyaha si loo kala saaro sawirka saxda ah
DenseNet waxay ku xidhaa lakab kasta dhammaan lakabyada dambe, taasoo dhiirigelinaysa dib-u-isticmaalka iyo fududaynta socodka qulqulka

Shabakadda Siamese iyo Khasaaraha Saddex-geesoodka ah
Su'aalaha soo noqnoqda
What is Highway Networks and Skip Connections?
Isku xidhka ka bood waxa ay macluumaadka u saamaxaysaa in ay ka boodaan lakabyada hore, iyo shabakadaha jidadku waxa ay ahaayeen nooca hore ee fikirkan. Waxay xalliyaan dhibaatada tababbarka shabakado aad u qoto dheer, kuwaas oo u gogol xaarayey ResNets iyo barashada qoto dheer ee casriga ah.
Mushkiladdee xudunta u ah ayaa isku xirnaanta ka boodi ay caawisaa xalinta shabakadaha aadka u qoto dheer?
Adiga oo siinaya wadooyin toos ah, ka bood isku xidhka ayaa u oggolaanaya gradients iyo calaamaduhu inay dhex maraan xirmooyin qoto dheer, taasoo ka dhigaysa shabakad aad u qoto dheer oo la tababari karo.
Muxuu xisaabiyaa block-ka haraaga aasaasiga ah?
Baloogga haraaga ah wuxuu ku daraa gelinta x wax soo saarka F(x), marka lakabku wuxuu bartaa oo keliya haraaga.
Maxaa dhiirigeliyay habka albaabbada ee shabakadaha waddooyinka?
Shabakadaha wadooyinka ayaa ka amaahday fikradda albaabada la bartay ee LSTM-yada si loo xakameeyo inta macluumaadka loo beddelayo iyada oo la adeegsanayo.
Shabakadda waddo-weyn, muxuu koontaroolayaa albaabka T(x) beddelka?
Wax-soo-saarku waa F(x)*T(x) + x*(1-T(x)), marka T ayaa go'aamisa dheelitirka u dhexeeya beddelka iyo qaadista gelinta.
Qaab dhismeedka casriga ah keebaa ku tiirsan isku xirka hadhaaga ee ku wareegsan sahayayaasheeda?
Transformers waxay dhigaan isku xirnaanta hadhaaga ah ee ku wareegsan labadaba feejignaantooda iyo quudin-horumarineed-hoosaadyada sidii naqshad caadi ah.
