Kobaca Horumarka leh ee GAN-yada
Horusocod u koraya ayaa tababara GAN isagoo ka bilaabaya go'aamo yaryar oo si tartiib tartiib ah ugu daraya lakabyo si loo gaaro sawirro heer sare ah.
Dulmar
It matters because it made stable, megapixel-quality GAN synthesis practical for the first time.
quusid qoto dheer
Waxaa soo bandhigay Karras et al. (NVIDIA) sanadka 2017, horumarka horumarka leh (ProGAN) wuxuu wax ka qabtaa xasilooni darada iyo gaabisnimada tababarka GANs si toos ah xal sare. Koronto-dhaliyaha iyo midab-takoorka labaduba waxay ku bilowdaan wax yar, 4x4 pixels, iyagoo baranaya qaab-dhismeedka baaxadda weyn. Lakabyo cusub oo labanlaabaya xallinta (8x8, 16x16, ilaa 1024x1024) ayaa markaa si asymmetrical ah loogu daraa labada shabakadood muddada tababarka. Muhiimad ahaan, lakab kasta oo cusub ayaa si habsami leh u libdhay iyadoo la isticmaalayo isku-dhafka alfa-ga toosan si aanay shabakadu uga naxin isbeddelka qaabdhismeedka degdega ah. Markaad barato sifooyin aan fiicneyn ka hor tafaasiisha wanaagsan, tababarku wuu xasiloon yahay, dhaqso ayuu isugu yimaadaa, wuxuuna soo saaraa wejiyada daacadnimada sare leh ee ka dhigay natiijooyinka CelebA-HQ caan. Waraaqda ayaa sidoo kale soo bandhigtay weecinta heerka-yar-yar oo la simay heerarka waxbarashada si loo sii xasiliyo tababarka.
Aragtida Farsamada
Fade-ku waa khiyaamada dhexe. Marka lagu daro block-xalinta sare, wax soo saarkeeda waxaa lagu daraa qaab la soo koobay oo ah qaraarkii hore iyadoo la isticmaalayo alfa miisaankeedu ka korayo 0 ilaa 1. Tani waxay u ogolaanaysaa lakabyada cusub miisaankooda inay si tartiib tartiib ah u kululaadaan halkii ay carqaladeyn lahaayeen wixii shabakadu hore u baratay. Nidaam isku mid ah ayaa ku dhaca takooraha. weecasho heerka Minibatch waxa ay ku lifaaqdaa sifo soo koobaysa kala duwanaanshiyaha dufcaddii, taas oo ka niyad jabinaysa koronto-dhaliyaha inuu burburo oo soo saaro xaddidan.
Saamaynta Istiraatijiyadeed
Xawaaraha iyo miisaanka
Visual AI wuxuu si otomaatig ah u samayn karaa baadhista, ogaanshaha, iyo sumadaynta hawlaha miisaanka.
Xulashada dhismayaasha
Kooxaha hal-abuurka leh waxay hindise karaan fikradaha si dhakhso leh iyagoo leh dib-u-eegis buugeed yar.
Kooxda iyo socodka shaqada
Hawlgalladu waxay isticmaali karaan calaamadaha muuqaalka iyo muuqaalka kuwaas oo markii hore adkeyd in la farsameeyo.
Mustaqbalka Koritaanka Horumarka ee GANs
Koritaanka horumarka leh ayaa ahaa aasaaska StyleGAN ee lagu dhisay, laakiin StyleGAN2 ayaa markii dambe muujisay in qaab-dhismeedka go'an ee leh isku xirka boodada iyo baloogyada haraaga ah ay la mid noqon karaan tayadooda iyada oo aan la helin jadwal la qorsheeyay, sidaa darteed korriin cad ayaa hoos u dhacay. Dhaxalka qoto dheer ayaa sii jira: jiil aan dhab ahayn-ilaa-fiican ayaa hadda u muuqda fidinta baaxadda leh, dhuumaha xallinta sare ee fidsan, iyo kor-u-qaadayaasha bannaan ee qarsoon. Fahamka korriinka horusocodka ah ayaa weli ah mid qiimo leh in la fahmo sababta kala sareynta, barashada-soo noqnoqoshada hoose ilaa-sare u dejiso tababbarka abuurista.
Dhaqangelinta Adduunka-dhabta ah
Soo saarida sawirada wejiga ee CelebA-HQ ee heerka sare ah ee muujiyay 1024x1024 GAN.
Soo saarista muunado tayo sare leh ee qaybaha kale sida qolalka hurdada (LSUN) iyo walxaha miisaanka leh.
U adeegida sidii meesha laga bilaabayo qaabdhismeedka qaabdhismeedka ee StyleGAN ay u fidisay jiilka la xakameyn karo.
Barista mabda'a tababbarka qallafsan-ilaa-fiican ee dib loogu isticmaalo dhuumaha wax-soo-saarka ee baaxadda leh iyo kuwa kala duwan.
Khatarta & Dariiqyada Ilaalada
Xuquuqda sawirka iyo ogolaanshaha waxay noqon kartaa khataro sharci ah haddii caddayntu aanay caddayn.
Waxqabadka moodeelku wuu ku kala duwanaan karaa iftiinka, tirakoobka, iyo deegaanka.
Wanaagga beenta ah waxa laga yaabaa inaan la dareemin ilaa xadka kalsoonida aan la kormeerin.
Qorshe Hawleedka Dhaqangelinta
Qeex shuruudaha aqbalida ee saxnaanta, dib u celinta, iyo kharashyada khaladka.
Ku tijaabi xogta ku habboon xaaladaha wax soo saarka dhabta ah.
Ku dar dib u eegis bini'aadamka si aad u hesho kalsoonida hoose ama saameeynta sare.

Su'aalaha soo noqnoqda
What is Progressive Growing of GANs?
Horusocod u koraya ayaa tababara GAN isagoo ka bilaabaya go'aamo yaryar oo si tartiib tartiib ah ugu daraya lakabyo si loo gaaro sawirro heer sare ah. Waa arrin sababtoo ah waxay samaysay xasilloon, megapixel-tayada GAN synthesis wax ku ool ah markii ugu horeysay.
Sidee buu GAN si tartiib tartiib ah u bilaabo tababarka?
Tababarku wuxuu ka bilaabmaa 4x4, halkaas oo shabakadu ay ku bartaan qaab dhismeed aan dhab ahayn, ka hor inta aan lagu darin lakabyo xallin sare leh.
Waa maxay faa'iidada ugu weyn ee xallinta si tartiib tartiib ah?
Barashada sifooyinka qalafsan waxay marka hore dejisaa tababarka waxayna dedejisaa isku-xidhnaanta marka la barbar dhigo weerarka xallinta bilawga ah.
Marka lakab cusub oo cusub lagu daro, sidee loo soo bandhigay?
Fadeexaanta toosan waxay isku daraa wax soo saarka lakabka cusub iyo soo saarista xallin hoose oo la soo koobay si ay shabakadu si tartiib tartiib ah ula qabsato.
Waa maxay sababta lakabyada loogu daray koronto-dhaliyaha iyo midab-takoorka labadaba?
Labada shabakadoodba way u koraan si isku mid ah si takooruhu u sii wato qiimaynta sawirada marka la eego xallinta koronto-dhaliyaha hadda.
Waa maxay ujeedada lakabka weecasho ee heerka-yar ee lagu soo bandhigay ProGAN?
Waxay ku darsataa tirakoob ku saabsan kala duwanaanshaha dufcaddii, iyadoo ku dhiirigelinaysa koronto-dhaliye inuu soo saaro wax soo saar kala duwan halkii uu burburin lahaa.
