Nvidia neural network imatembenuza zojambula zosavuta kukhala malo okongola

Mathithi a wosuta fodya ndi mathithi a munthu wathanzi

Tonse timadziwa kujambula kadzidzi. Choyamba muyenera kujambula chowulungika, ndiye bwalo lina, ndiyeno - kupeza kadzidzi wokongola. Zoonadi, izi ndi nthabwala, ndi zachikale kwambiri, koma akatswiri a Nvidia anayesa kuti zongopekazo zichitike.

Chitukuko chatsopano, yomwe imatchedwa GauGAN, imapanga malo okongola kuchokera ku zojambula zosavuta (zosavuta kwenikweni - zozungulira, mizere ndi zonse). Inde, chitukukochi chimachokera ku matekinoloje amakono - omwe ndi ma generative adversarial neural network.

GauGAN imakupatsani mwayi wopanga maiko okongola - osati kungosangalatsa, komanso ntchito. Kotero, omanga, okonza malo, opanga masewera - onse amatha kuphunzira chinachake chothandiza. Luntha lochita kupanga nthawi yomweyo "zimamvetsetsa" zomwe munthu akufuna ndikukwaniritsa lingaliro loyambirira ndi tsatanetsatane wambiri.

"Kuganiza mozama pakupanga mapangidwe ndikosavuta mothandizidwa ndi GauGAN, popeza burashi yanzeru imatha kuthandizira chojambula choyambirira powonjezera zithunzi zabwino," adatero katswiri wina wa GauGAN.

Ogwiritsa ntchito chida ichi akhoza kusintha lingaliro loyambirira, kusintha malo kapena chithunzi china, kuwonjezera thambo, mchenga, nyanja, ndi zina zotero. Chilichonse chomwe mtima wanu umafuna, ndipo kuwonjezera kumatenga masekondi angapo.

Neural network idaphunzitsidwa pogwiritsa ntchito nkhokwe ya zithunzi mamiliyoni ambiri. Chifukwa cha izi, dongosololi limatha kumvetsetsa zomwe munthu akufuna komanso momwe angakwaniritsire zomwe akufuna. Komanso, neural network siyiyiwala za zing'onozing'ono. Chifukwa chake, ngati mujambula dziwe ndi mitengo ina pafupi ndi iyo, ndiye kuti malowo akatsitsimutsidwa, zinthu zonse zapafupi zidzawonetsedwa pagalasi lamadzi a dziwe.

Mutha kudziwa dongosolo lomwe mawonekedwe owoneka ayenera kukhala - amatha kuphimbidwa ndi udzu, matalala, madzi kapena mchenga. Zonsezi zikhoza kusinthidwa mumphindi, kuti chisanu chikhale mchenga ndipo mmalo mwa chipale chofewa, wojambula amapeza malo achipululu.

“Zili ngati buku lopaka utoto limene limafotokoza malo oti mtengowo uyenera kukhala, kumene dzuŵa lili, ndi kumene kuli kumwamba. Kenako, itatha ntchito yoyamba, neural network imapangitsa chithunzicho kukhala chamoyo, kuwonjezera zofunikira ndi mawonekedwe ake, kujambula zowunikira. Zonsezi zimachokera pazithunzi zenizeni, "akutero m'modzi mwa opanga.

Ngakhale dongosololi lilibe "kumvetsetsa" kwa dziko lenileni, dongosololi limapanga malo ochititsa chidwi. Izi ndichifukwa choti maukonde awiri a neural amagwiritsidwa ntchito pano, jenereta ndi tsankho. Jenereta imapanga chithunzi ndikuwonetsa kwa wosankha. Iye, kutengera mamiliyoni a zithunzi zomwe zidawonedwa kale, amasankha zosankha zenizeni.

Ichi ndichifukwa chake jenereta "amadziwa" pomwe zowunikira ziyenera kukhala. Ndikoyenera kudziwa kuti chidacho ndi chosinthika kwambiri komanso chimakhala ndi zoikamo zambiri. Kotero, ndi izo, mukhoza kujambula, kusinthira ku kalembedwe ka wojambula wina, kapena kungosewera ndi kuwonjezera mwamsanga kutuluka kwa dzuwa kapena kulowa kwa dzuwa.

Okonzawo amanena kuti dongosololi silimangotenga zithunzi kuchokera kwinakwake, kuziwonjezera pamodzi ndikupeza zotsatira. Ayi, "zithunzi" zonse zolandiridwa zimapangidwa. Ndiko kuti, neural network "imapanga" ngati wojambula weniweni (kapena bwino).

Pakalipano, pulogalamuyi sichipezeka mwaufulu, koma posachedwa idzayesa kuyesa ntchito. Izi zitha kuchitika ku GPU Technology Conference 2019, yomwe ikuchitika ku California. Omwe ali ndi mwayi omwe adatha kuyendera chiwonetserochi akhoza kuyesa kale GauGAN.

Ma Neural network akhala akuphunzitsidwa kwa nthawi yayitali kutenga nawo mbali pakupanga. Mwachitsanzo, chaka chatha, ena a iwo akhoza kupanga zitsanzo za 3D. Kuphatikiza apo, opanga kuchokera ku DeepMind adaphunzitsa ma neural network kuti abwezeretse malo okhala ndi mbali zitatu ndi zinthu kuchokera pazithunzi, zithunzi, ndi zojambula. Kuti mupangenso chithunzi chosavuta, chithunzi chimodzi ndi chokwanira kwa neural network, kupanga zinthu zovuta kwambiri, zithunzi zisanu zimafunika "kuphunzitsa".

Ponena za GauGAN, chida ichi chidzapeza ntchito yoyenera yamalonda - madera ambiri abizinesi ndi sayansi amafunikira ntchito zotere.
