\"Neuralna
\nVodopad pu\u0161a\u010da i vodopad zdravog \u010dovjeka<\/p>\n

Svi znamo kako nacrtati sova. Prvo treba nacrtati oval, zatim jo\u0161 jednu kru\u017enicu, a onda \u2014 dobijamo prekrasnu sovu. Naravno, to je \u0161ala, i to vrlo stara, ali in\u017eenjeri Nvidije su se potrudili da ma\u0161ta postane stvarnost. <\/p>\n

Nova razvojna tema<\/a><\/noindex>, koja se zove GauGAN, stvara prekrasne krajolike iz vrlo jednostavnih skica (zaista jednostavnih \u2014 kru\u017enice, linije i to je to). Naravno, u temelju ovog razvoja le\u017ee moderne tehnologije \u2014 to\u010dnije, generativne adversarijalne neuralne mre\u017ee.
\n<\/a><\/noindex>
\nGauGAN omogu\u0107uje stvaranje \u017eivopisnih virtualnih svjetova \u2014 i to ne samo za zabavu, ve\u0107 i za rad. Tako arhitekti, stru\u010dnjaci za pejza\u017eni dizajn, programeri igara \u2014 svi oni mogu izvu\u0107i ne\u0161to korisno. Umjetna inteligencija odmah 'razumije' \u0161to \u010dovjek \u017eeli i dodaje izvornom konceptu ogromnu koli\u010dinu detalja. <\/p>\n

\u201eMisaoni proces u razvoju dizajna mnogo je lak\u0161i uz pomo\u0107 GauGAN-a, budu\u0107i da pametna \u010detkica mo\u017ee dopuniti izvorni skiciraju\u0107i dodaju\u0107i kvalitetne slike\u201c, izjavio je jedan od razvijatelja GauGAN-a.<\/p>\n

Korisnici ovog alata mogu mijenjati izvorni koncept, modificirati krajolik ili drugo prikazano, dodavati nebo, pijesak, more itd. Sve \u0161to srce po\u017eeli, a dodavanje se odvija za nekoliko sekundi.<\/p>\n

Neuralna mre\u017ea je trenirana koriste\u0107i bazu od milijuna slika. Zbog toga sustav mo\u017ee razumjeti \u0161to \u010dovjek \u017eeli i kako to posti\u0107i. Nadalje, neuralna mre\u017ea ne zaboravlja na najsitnije detalje. Tako, ako se shematski nacrta ribnjak i neka stabla u blizini, nakon o\u017eivljavanja krajolika svi obli\u017enji objekti bit \u0107e reflektirani u zrcalu vode ribnjaka.<\/p>\n

Sustavu se mo\u017ee odrediti kakva bi trebala biti vidljiva povr\u0161ina \u2014 mo\u017ee biti prekrivena travom, snijegom, vodom ili pijeskom. Sve to mo\u017ee se preoblikovati u sekundi, tako da snijeg postane pijesak i umjesto snije\u017enog prostranstva umjetnik dobiva pustinjski krajolik. <\/p>\n

\u201eTo je poput bojanke koja pokazuje gdje postaviti drvo, gdje sunce, a gdje nebo. Zatim, nakon prvotnog zadatka, neuronska mre\u017ea o\u017eivljava sliku, dodaje potrebne detalje i teksture, crta odraze. Sve ovo se temelji na stvarnim slikama\u201c, ka\u017ee jedan od developera. <\/p>\n

\r\n \"Pogledajte\r\n
<\/div>\r\n <\/div><\/center>
\nIako sustavu nedostaje \u201erazumijevanje\u201c stvarnog svijeta, sustav stvara impresivne pejza\u017ee. Sve to zahvaljuju\u0107i kori\u0161tenju dvije neuronske mre\u017ee, generatora i diskriminatora. Generator stvara sliku i prikazuje je diskriminatoru. On, temelje\u0107i se na milijunima ve\u0107 vi\u0111enih slika, odabire najrealisti\u010dnije opcije. <\/p>\n

Zato generator \u201ezna\u201c gdje trebaju biti odrazi. Valja napomenuti da je alat vrlo fleksibilan i opremljen brojnim pode\u0161avanjima. Pomo\u0107u njega mo\u017eete slikati slike prilago\u0111avaju\u0107i se stilu odre\u0111enog umjetnika ili se jednostavno zabavljati brzom dodavanjem izlaska ili zalaska sunca. <\/p>\n

Developeri tvrde da sustav ne uzima slike s nekog mjesta, sastavlja ih i dobiva rezultat. Ne, sve dobivene \u201eslike\u201c su generirane. Drugim rije\u010dima, neuronska mre\u017ea \u201estvara\u201c poput pravog umjetnika (ili \u010dak bolje).<\/p>\n

Program trenutno nije dostupan javnosti, ali uskoro \u0107e ga mo\u0107i isprobati. To \u0107e biti mogu\u0107e na tehnolo\u0161koj izlo\u017ebi GPU Technology Conference 2019, koja se trenutno odr\u017eava u Kaliforniji. Sretnici koji su posjetili izlo\u017ebu ve\u0107 mogu testirati GauGAN.<\/p>\n

Neuronske mre\u017ee ve\u0107 dugo sudjeluju u kreativnom procesu. Na primjer, pro\u0161le godine, neke od njih mogle su stvarati 3D modele<\/a><\/noindex>. Osim toga, developeri iz DeepMind-a obu\u010dili su neuronsku mre\u017eu da rekonstrui\u0161e trodimenzionalne prostore i objekte prema crte\u017eima, fotografijama, skicama. Da bi rekreirali jednostavnu figuru, neuronskim mre\u017eama dovoljna je jedna slika, dok za kreiranje slo\u017eenijih objekata treba pet slika za \u201etreniranje\u201c.<\/p>\n

\u0160to se ti\u010de GauGAN-a, ovaj alat \u0107e zasigurno prona\u0107i dostojnu komercijalnu primjenu \u2014 mnogim granama poslovanja i znanosti potrebni su sli\u010dni servisi.<\/p>\n
