I-NVIDIA izama ngenkuthalo emkhakheni wokufunda okujulile, futhi imiphumela yomsebenzi wayo kwesinye isikhathi iyathakazelisa kakhulu. Inkampani imemezele kwa-GDC 2019 ukudalwa kwe-GauGAN, uhlelo lokusebenza lokudweba oluhlakaniphile olusebenzisa imodeli yokufunda ejulile ukwenza izinguqulo ze-photorealistic zemidwebo elula. Igama lohlelo lokusebenza liqondise kuciko lase-France le-post-impressionist u-Paul Gauguin kanye nokusetshenziswa kwesofthiwe kwamanethiwekhi okuphikisana nawo (ama-GAN) ukuze kwakhe izithombe ezilingisa imidwebo ngokweqiniso.
Isebenza kanjani i-GauGAN? Ngokwencazelo yenkampani, uhlelo lokusebenza lufana "nebhulashi elihlakaniphile" eligcwalisa imininingwane yomdwebo womsebenzisi (i-NVIDIA iwubiza ngokuthi "imephu yokuhlukanisa"). Empeleni, umsebenzisi noma umdwebi uvele asethe icebo lalokho afuna ukukubona ekugcineni, futhi alebule ingxenye ngayinye, ekhombisa ukuthi kufanele ibe yini. U-GauGAN ube esethatha izintambo, egcwalisa imininingwane eyengeziwe futhi enze imidwebo ibe ngokoqobo.
Iqeqeshwe ngezigidi zezithombe zobuciko, imodeli yokufunda ejulile ibe isigcwalisa indawo ngemiphumela encomekayo (kodwa engahlali iphelele). Uma udweba ichibi, izakhi eziseduze njengezihlahla namadwala zizobonakala emanzini. Kwanele ukushintsha ilebula yesigaba kusuka "etshanini" kuya "eqhweni", futhi isithombe sonke sizoshintsha, siphenduke sibe ebusika, futhi izihlahla ezinamaqabunga zizoba ngenalutho. Ukuze uqonde ukuthi sikhuluma ngani, ungabuka ividiyo engezansi.
Kuhle futhi ukuqaphela ukuthi nakuba i-GauGAN isebenzisa ulwazi olubanzi olusekelwe kwezinye izithombe eziningi ukuze idale imisebenzi yokugcina, lezi zisabhekwa njengezokuqala njengoba uhlelo lokusebenza lukhiqiza izithombe ezintsha ngokuphelele.
Umhleli omusha wezithombe ezihlakaniphile ze-NVIDIA akakhawulelwe ezigcawini zemvelo kuphela noma ukuma kwezwe—uhlelo lokusebenza lungangeza izakhiwo, imigwaqo, ngisho nabantu. I-GauGAN iphinde ivumele abasebenzisi ukuthi basebenzise izihlungi, benze isitayela umphumela ukuze uvumelane nesitayela abasifisayo. Izihlungi ezinjalo, phakathi kwezinye izinto, zingalingisa isitayela somculi othile (isibonelo, uVan Gon) noma zilungise ukukhanya kwesigcawu, ziguqule izithombe kusukela emini kuya ebusuku.
Akukacaci ukuthi i-GauGAN izoke ikhishwe ukuze isetshenziswe ngabathengi nsuku zonke, kodwa ngicabanga ukuthi ngokuhamba kwesikhathi abasebenzisi abajwayelekile bangathola amathuluzi amahle awusizo njengalawa, okwenza umsebenzi ube lula ezindaweni ezahlukahlukene: kusuka ekwakhiweni kwezakhiwo nasekufanekiseni kuya ekuthuthukisweni komdlalo.
Nokho, kusisetshenziswa se-NVIDIA AI Playground, labo abanentshisekelo bangajwayelana namakhono athile okufunda komshini. Isibonelo, ekubonisweni kokudlulisa Isitayela Sobuciko okhona lapho, ungacubungula noma yisiphi isithombe ngesitayela samaciko adumile.
Okunye ukuhlola okufanayo okuvela ku-NVIDIA kufaka phakathi ucwaningo olubonisa ukuthi imithelela yokubuka ekhiqizwe yi-AI ingahlanganiswa kanjani nepayipi elivamile lokurabha. Umphumela uwuhlelo lwezithombe oluxubile olungasetshenziswa kumidlalo, amamuvi kanye neqiniso elibonakalayo. Esinye isibonelo esifanayo i-algorithm yokuguqula izitaladi ezigcwele iqhwa zibe ezasehlobo, ezithuthukiswe ochwepheshe benkampani ukuze bathole ukuqeqeshwa kokushayela okuzenzakalelayo okuphumelelayo.
