NVIDIA yatulutsa kachidindo ka makina ophunzirira makina a SPADE (GauGAN), omwe amatha kupanga mawonekedwe owoneka bwino kuchokera pazithunzi zowoneka bwino, komanso mitundu yosaphunzitsidwa bwino yokhudzana ndi ntchitoyi. Dongosololi lidawonetsedwa mu Marichi pamsonkhano wa GTC 2019, koma code idangosindikizidwa dzulo. Zomwe zachitikazi zimatsegulidwa ndi layisensi yaulere CC BY-NC-SA 4.0 (Creative Commons Attribution-NonCommerce-ShareAlike 4.0), kulola kugwiritsidwa ntchito pazinthu zopanda malonda. Khodiyo imalembedwa mu Python pogwiritsa ntchito dongosolo la PyTorch.
Zojambulazo zimajambula ngati mapu a magawo omwe amatsimikizira malo omwe zinthuzo zikuyandikira. Chikhalidwe cha zinthu zopangidwa chimatchulidwa pogwiritsa ntchito zizindikiro zamtundu. Mwachitsanzo, buluu kudzaza kumwamba, buluu kukhala madzi, mdima wobiriwira kukhala mitengo, wobiriwira wobiriwira kukhala udzu, bulauni wopepuka kukhala miyala, bulauni kukhala mapiri, imvi kukhala chipale chofewa, mzere wabulauni umasanduka msewu, ndi buluu. mzere mumtsinje. Kuonjezera apo, kutengera kusankha kwa zithunzi zowonetsera, kalembedwe kake ndi nthawi ya tsiku zimatsimikiziridwa. Chida chomwe chaperekedwa chopangira maiko enieni chingakhale chothandiza kwa akatswiri osiyanasiyana, kuyambira omanga mapulani ndi okonza mizinda mpaka opanga masewera ndi opanga mawonekedwe.
Zinthu zimapangidwa ndi generative adversarial neural network (GAN), yomwe imapanga zithunzi zenizeni kutengera mapu agawo, kubwereka zambiri kuchokera kumtundu wophunzitsidwa kale pazithunzi mamiliyoni angapo. Mosiyana ndi machitidwe opangira zithunzi omwe adapangidwa kale, njira yomwe ikufunsidwayo imachokera pakugwiritsa ntchito kusintha kwa malo komwe kumatsatiridwa ndi kusintha kotengera kuphunzira pamakina. Kukonza mapu okhala ndi magawo m'malo mwa semantic markup kumakupatsani mwayi wopeza zotsatira zofananira ndikuwongolera masitayelo.
Kuti mukwaniritse zenizeni, ma neural network awiri amapikisana wina ndi mnzake: jenereta ndi tsankho. Jenereta imapanga zithunzi zochokera kuzinthu zosakaniza za zithunzi zenizeni, ndipo wosankhana amazindikira zolakwika zomwe zingatheke kuchokera kuzithunzi zenizeni. Zotsatira zake, mayankho amapangidwa, pamaziko omwe jenereta imayamba kupanga zitsanzo zabwino kwambiri mpaka wosankhana amasiya kuwasiyanitsa ndi zenizeni.
