\nGauGAN umo\u017e\u0148uje vytv\u00e1ra\u0165 farebn\u00e9 virtu\u00e1lne svety \u2014 a nielen na z\u00e1bavu, ale aj na pr\u00e1cu.

\u201eBrainstorming v oblasti v\u00fdvoja dizajnu je s pomocou GauGAN omnoho jednoduch\u0161\u00ed, preto\u017ee inteligentn\u00fd \u0161tetec m\u00f4\u017ee doplni\u0165 p\u00f4vodn\u00fd n\u00e1\u010drt o kvalitn\u00e9 obr\u00e1zky,\u201c povedal jeden z v\u00fdvoj\u00e1rov GauGAN.<\/p>\n

V\u0161etko, \u010do si du\u0161a za\u017eiada, pri\u010dom prid\u00e1vanie trv\u00e1 len p\u00e1r sek\u00fand.<\/p>\n

Neur\u00f3nov\u00fa sie\u0165 tr\u00e9novali s pou\u017eit\u00edm datab\u00e1zy mili\u00f3nov obr\u00e1zkov.

Navy\u0161e neur\u00f3nov\u00e1 sie\u0165 nezab\u00fada na najmen\u0161ie detaily. Tak\u017ee ak nakresl\u00edte schematicky rybn\u00edk a nejak\u00e9 stromy ved\u013ea neho, po o\u017eiven\u00ed krajiny sa v\u0161etky bl\u00edzke objekty odr\u00e1\u017eaj\u00fa v zrkadle vody rybn\u00edka.<\/p>\n

\u201eJe to ako kni\u017eka na vyma\u013eovanie, v ktorej sa hovor\u00ed, kde umiestni\u0165 stromy, kde \u2014 slnko a kde \u2014 oblohu. Potom, po za\u010diatku \u00falohy, neur\u00f3nov\u00e1 sie\u0165 o\u017eivuje obraz, prid\u00e1va potrebn\u00e9 detaily a text\u00fary, kresl\u00ed odrazy. V\u0161etko to vych\u00e1dza z re\u00e1lnych obr\u00e1zkov\u201c, hovor\u00ed jeden z v\u00fdvoj\u00e1rov. <\/p>\n

Neur\u00f3nov\u00e9 siete sa u\u017e dlho u\u010dia zap\u00e1ja\u0165 do tvoriv\u00e9ho procesu. Napr\u00edklad, minul\u00fd rok niektor\u00e9 z nich dok\u00e1zali vytv\u00e1ra\u0165 3D modely<\/a><\/noindex>. Okrem toho, v\u00fdvoj\u00e1ri z DeepMind vy\u0161kolili neur\u00f3nov\u00fa sie\u0165 na obnovu trojrozmern\u00fdch priestorov a objektov pod\u013ea kresieb, fotografi\u00ed a n\u00e1\u010drtov. Pre obnovenie jednoduchej fig\u00fary sta\u010d\u00ed neur\u00f3novej sieti jedno obr\u00e1zok, pre vytvorenie zlo\u017eitej\u0161\u00edch objektov je potrebn\u00fdch p\u00e4\u0165 obr\u00e1zkov na \u201etr\u00e9ning\u201c.<\/p>\n
