Chidule cha chidziwitso

Generative Adversarial Networks (GANs), yomwe imadziwika kuti imapanga zozama, imapanga data yopangidwa yomwe imatengera nkhope, mawu, ndi machitidwe enieni. Kugwiritsa ntchito kwawo kumayambira kukulitsa Adobe Photoshop mpaka kupanga zosefera zenizeni pa Snapchat. Komabe, ma GAN amakhala ndi nkhawa, chifukwa nthawi zambiri amagwiritsidwa ntchito kupanga makanema osokeretsa komanso kufalitsa zabodza. Pazaumoyo, pali nkhawa pazinsinsi za data za odwala mu maphunziro a GAN. Ngakhale pali zovuta izi, ma GAN ali ndi ntchito zopindulitsa, monga kuthandizira kufufuza zaumbanda. Kugwiritsa ntchito kwawo mofala m'magawo osiyanasiyana, kuphatikiza kupanga mafilimu ndi kutsatsa, kwapangitsa kuti pakhale njira zolimba zachinsinsi komanso kuwongolera boma paukadaulo wa GAN.

Generative adversarial networks (GANs).

GAN ndi mtundu wa neural network yakuya yomwe imatha kupanga data yatsopano yofanana ndi data yomwe amaphunzitsidwa. Mipiringidzo iwiri ikuluikulu yomwe imapikisana kuti ipange zolengedwa zamasomphenya imatchedwa jenereta ndi kusankhana. Jenereta ali ndi udindo wopanga deta yatsopano, pamene wosankhana amayesa kusiyanitsa pakati pa deta yopangidwa ndi deta yophunzitsira. Jenereta nthawi zonse ikuyesera kupusitsa watsankho popanga chidziwitso chomwe chikuwoneka ngati chenichenicho. Kuti achite izi, jeneretayo iyenera kuphunzira kugawa komwe kumayambira, kulola ma GAN kupanga zidziwitso zatsopano popanda kuloweza.

Pamene ma GAN adapangidwa koyamba mu 2014 ndi wasayansi wofufuza wa Google Ian Goodfellow ndi osewera nawo, ma aligorivimu adawonetsa lonjezo lalikulu la kuphunzira pamakina. Kuyambira pamenepo, ma GAN awona ntchito zambiri zenizeni padziko lonse lapansi m'mafakitale osiyanasiyana. Mwachitsanzo, Adobe imagwiritsa ntchito ma GAN pa Photoshop wam'badwo wotsatira. Google imagwiritsa ntchito mphamvu za GAN popanga zolemba ndi zithunzi. IBM imagwiritsa ntchito bwino ma GAN powonjezera deta. Snapchat imagwiritsa ntchito zosefera zabwino za zithunzi ndi Disney pazosankha zapamwamba. 

Zosokoneza

Ngakhale GAN idapangidwa kuti ipititse patsogolo kuphunzira pamakina, kugwiritsa ntchito kwake kudadutsa magawo okayikitsa. Mwachitsanzo, makanema ozama amapangidwa nthawi zonse kuti azitengera anthu enieni ndikupangitsa kuti aziwoneka ngati akuchita kapena kunena zomwe sananene. Mwachitsanzo, panali kanema wa Purezidenti wakale wa US, Barack Obama, akutcha mnzake wakale wa Purezidenti wa US, a Donald Trump, mawu achipongwe ndipo wamkulu wa Facebook, Mark Zuckerburg, akudzitama kuti atha kuwongolera mabiliyoni azinthu zomwe zidabedwa. Palibe chilichonse mwa izi chomwe chinachitika m'moyo weniweni. Kuonjezera apo, mavidiyo ambiri a deepfake amalunjika kwa akazi otchuka ndikuwayika mu zolaula. Ma GAN amathanso kupanga zithunzi zopeka kuyambira poyambira. Mwachitsanzo, maakaunti angapo atolankhani akuzama pa LinkedIn ndi Twitter adakhala opangidwa ndi AI. Mbiri zopangira izi zitha kugwiritsidwa ntchito kupanga zolemba zomveka bwino komanso zidutswa za utsogoleri zomwe ofalitsa angagwiritse ntchito. 

Pakadali pano, m'gawo lazaumoyo, pali nkhawa zomwe zikuchulukirachulukira pazomwe zitha kutayidwa pogwiritsa ntchito nkhokwe yeniyeni ya odwala monga chidziwitso chophunzitsira ma algorithms. Ofufuza ena amanena kuti payenera kukhala chitetezo chowonjezera kapena masking layer kuti ateteze zambiri zaumwini. Komabe, ngakhale kuti GAN imadziwika kuti imatha kunyenga anthu, ili ndi zabwino. Mwachitsanzo, mu May 2022, apolisi a ku Netherlands anajambulanso vidiyo yosonyeza mnyamata wazaka 13 yemwe anaphedwa mu 2003. Pogwiritsa ntchito zithunzi zenizeni za munthu amene anaphedwayo, apolisi akuyembekeza kulimbikitsa anthu kuti akumbukire munthu amene anaphedwayo ndi kufotokoza za munthuyo. zatsopano zokhudzana ndi chimfine. Apolisi ati adalandira kale maupangiri angapo koma akuyenera kuyang'ana kumbuyo kuti atsimikizire.

Kugwiritsa ntchito ma generative adversarial network (GANs)

Ntchito zina zama generative adversarial network (GANs) zitha kuphatikiza: 

• Makampani opanga mafilimu amapanga zinthu zozama kuti aziyika ochita sewero ndi kuwomberanso makanema omwe atulutsidwa pambuyo pake. Njirayi imatha kutanthauzira kupulumutsa mtengo kwanthawi yayitali chifukwa sangafunikire kulipira ochita nawo ntchito ndi ogwira nawo ntchito.
• Kuchulukirachulukira kwa zolemba ndi makanema akuzama kulimbikitsa malingaliro ndi zokopa pazandale zosiyanasiyana.
• Makampani omwe amagwiritsa ntchito makanema opangidwa kuti apange makampeni odziwika bwino komanso otsatsa osalemba ganyu anthu enieni pambali paopanga mapulogalamu.
• Magulu omwe amalimbikitsa chitetezo chazinsinsi za data pazaumoyo ndi zidziwitso zina zaumwini. Kukankhira kumbuyoku kungakakamize makampani kupanga deta yophunzitsira yomwe siimachokera ku database yeniyeni. Komabe, zotsatira sizingakhale zolondola.
• Maboma omwe amayang'anira ndi kuyang'anira makampani omwe amapanga ukadaulo wa GAN kuti awonetsetse kuti ukadaulo sunagwiritsidwe ntchito pofalitsa zabodza komanso zachinyengo.

Mafunso oti muyankhepo

• Kodi mwakumanapo ndi ukadaulo wa GAN? Kodi chochitikacho chinali chotani?
• Kodi makampani ndi maboma angawonetse bwanji kuti GAN ikugwiritsidwa ntchito moyenera?
