I-NVIDIA ivula ikhodi yesistimu yokufunda yomshini ehlanganisa ukubukeka kwezwe kusuka kumidwebo

Inkampani ye-NVIDIA eshicilelwe amakhodi omthombo wesistimu yokufunda komshini IZIMBALI (GauGAN), ekuvumela ukuthi uhlanganise izindawo ezingokoqobo ezisuselwa kumidwebo enzima, kanye naleyo ehlotshaniswa nephrojekthi. amamodeli aqeqeshiwe. Uhlelo kwaba kubonisiwe ngoMashi engqungqutheleni ye-GTC 2019, kodwa ikhodi ishicilelwe izolo. Intuthuko vula ngaphansi kwelayisensi yobunikazi I-CC BY-NC-SA 4.0 (Creative Commons Attribution-NonCommerce-ShareAlike 4.0), evumela ukusetshenziswa okungezona ezokuthengisa kuphela. Ikhodi ibhalwe ngePython kusetshenziswa uhlaka I-PyTorch.

Imidwebo idwetshwa ngendlela yemephu ehlukanisiwe enquma ukubekwa kwezinto cishe endaweni yesehlakalo. Ubunjalo bezinto ezikhiqiziwe bucaciswe kusetshenziswa amamaki ombala. Ngokwesibonelo, umbala oluhlaza okwesibhakabhaka ushintsha ube esibhakabhakeni, oluhlaza okwesibhakabhaka ube amanzi, oluhlaza okotshani ube yizihlahla, oluhlaza okotshani okhanyayo ube utshani, onsundu ngokukhanyayo ube amadwala, onsundu ngokumnyama ube izintaba, ompunga ube yiqhwa, umugqa onsundu uguquke ube umgwaqo, noluhlaza okwesibhakabhaka. umugqa emfuleni Ukwengeza, ngokusekelwe ekukhethweni kwezithombe eziyisethenjwa, isitayela sokuqamba sisonke kanye nesikhathi sosuku kuyanqunywa. Ithuluzi elihlongozwayo lokudala imihlaba ebonakalayo lingaba usizo kochwepheshe abahlukahlukene, kusukela kubadwebi bezakhiwo nabahleli bedolobha ukuya konjiniyela begeyimu nabaklami bendawo.

Izinto zihlanganiswa yi-generative adversarial neural network (GAN), okudala izithombe ezingokoqobo ezisuselwe kumephu eyisikimu ehlukaniswe izingxenye, eboleka imininingwane kumodeli eqeqeshwe kusengaphambili ezithombeni eziyizigidi ezimbalwa. Ngokungafani nezinhlelo zokuhlanganisa izithombe ezakhiwe ngaphambilini, indlela ehlongozwayo isekelwe ekusetshenzisweni koguquko lwendawo oluguquguqukayo olulandelwa ukuguqulwa okusekelwe ekufundeni komshini. Ukucubungula imephu ehlukanisiwe esikhundleni semakhaphu ye-semantic kukuvumela ukuthi uzuze imiphumela efana ncamashi futhi ulawule isitayela.

Ukuze kuzuzwe okungokoqobo, amanethiwekhi amabili e-neural ayancintisana: ijeneretha kanye nomcwasi. Ijeneretha ikhiqiza izithombe ezisekelwe ekuxubeni kwezinto zezithombe zangempela, futhi umcwasi ukhomba ukuphambuka okungenzeka ezithombeni zangempela. Ngenxa yalokho, kwakhiwa impendulo, ngesisekelo lapho i-generator iqala ukuhlanganisa amasampula angcono kakhulu kuze kube yilapho umbandlululi eyeka ukuhlukanisa phakathi kwangempela.
