\"Re\u021beaua
\nCascada fum\u0103torului \u0219i cascada omului s\u0103n\u0103tos<\/p>\n

To\u021bi \u0219tim cum se deseneaz\u0103 o bufni\u021b\u0103. Trebuie mai \u00eent\u00e2i s\u0103 desenezi un oval, apoi o alt\u0103 cerc, iar apoi \u2014 ob\u021bii o bufni\u021b\u0103 splendid\u0103. Desigur, aceasta este o glum\u0103, una foarte veche, dar inginerii de la Nvidia s-au str\u0103duit s\u0103 fac\u0103 din imagina\u021bie o realitate. <\/p>\n

Noua dezvoltare<\/a><\/noindex>, denumit\u0103 GauGAN, creeaz\u0103 peisaje superbe din schi\u021be foarte simple (cu adev\u0103rat simple \u2014 cercuri, linii \u0219i at\u00e2t). Desigur, la baza acestei dezvolt\u0103ri stau tehnologii moderne \u2014 mai precis, re\u021bele neuronale antagoniste generative.
\n<\/a><\/noindex>
\nGauGAN permite crearea de lumi virtuale colorate \u2014 \u0219i nu doar pentru distrac\u021bie, ci \u0219i pentru munc\u0103. A\u0219adar, arhitec\u021bii, speciali\u0219tii \u00een design peisagistic, dezvoltatorii de jocuri \u2014 to\u021bi pot ob\u021bine ceva util. Inteligen\u021ba artificial\u0103 \u00een\u021belege instantaneu ce \u00ee\u0219i dore\u0219te omul \u0219i completeaz\u0103 ideea ini\u021bial\u0103 cu un num\u0103r uria\u0219 de detalii. <\/p>\n

\u201eSesiunile de brainstorming pentru dezvoltarea designului sunt mult mai u\u0219or de realizat cu ajutorul GauGAN, deoarece pensula inteligent\u0103 poate s\u0103 completeze schi\u021ba ini\u021bial\u0103, ad\u0103ug\u00e2nd imagini de calitate\u201d, a declarat unul dintre dezvoltatorii GauGAN.<\/p>\n

Utilizatorii acestui instrument pot modifica concep\u021bia ini\u021bial\u0103, adapta peisajul sau alt\u0103 imagine, ad\u0103ug\u00e2nd cer, nisip, mare etc. Tot ceea ce \u00ee\u0219i dore\u0219te sufletul, iar ad\u0103ugarea se face \u00een doar c\u00e2teva secunde.<\/p>\n

Re\u021beaua neuronal\u0103 a fost antrenat\u0103 folosind o baz\u0103 de milioane de imagini. Datorit\u0103 acestui fapt, sistemul poate s\u0103 \u00een\u021beleag\u0103 ce \u00ee\u0219i dore\u0219te omul \u0219i cum s\u0103 ob\u021bin\u0103 rezultatul dorit. De asemenea, re\u021beaua neuronal\u0103 nu uit\u0103 de cele mai mici detalii. De exemplu, dac\u0103 se deseneaz\u0103 schematic un iaz \u0219i c\u00e2teva copaci \u00een apropiere, atunci dup\u0103 animarea peisajului, toate obiectele din apropiere se vor reflecta \u00een oglinda apei iazului.<\/p>\n

Sistemul poate indica cum ar trebui s\u0103 fie suprafa\u021ba vizibil\u0103 \u2014 aceasta poate fi acoperit\u0103 cu iarb\u0103, z\u0103pad\u0103, ap\u0103 sau nisip. Totul poate fi transformat \u00een c\u00e2teva secunde, astfel c\u0103 z\u0103pada va deveni nisip, iar \u00een loc de o pustietate \u00eenz\u0103pezit\u0103, artistul va ob\u021bine un peisaj de de\u0219ert. <\/p>\n

\u201eEste ca o carte de colorat, care arat\u0103 unde ar trebui s\u0103 fie copacul, unde soarele \u0219i unde cerul. Apoi, dup\u0103 sarcina ini\u021bial\u0103, re\u021beaua neuronal\u0103 anim\u0103 imaginea, adaug\u0103 detalii \u0219i texturi necesare, contureaz\u0103 reflexiile. Totul se bazeaz\u0103 pe imagini reale\u201d, spune unul dintre dezvoltatori. <\/p>\n

\r\n \"Reda\u021bi\r\n
<\/div>\r\n <\/div><\/center>
\nDe\u0219i sistemul \u00eei lipse\u0219te \u201e\u00een\u021belegerea\u201d lumii reale, acesta creeaz\u0103 peisaje impresionante. Totul se datoreaz\u0103 utiliz\u0103rii a dou\u0103 re\u021bele neuronale: un generator \u0219i un discriminator. Generatorul creeaz\u0103 imaginea \u0219i o prezint\u0103 discriminatorului. Acesta, baz\u00e2ndu-se pe milioane de imagini v\u0103zute anterior, selecteaz\u0103 cele mai realiste op\u021biuni. <\/p>\n

De aceea generatorul \u201e\u0219tie\u201d unde ar trebui s\u0103 fie reflexiile. Merit\u0103 men\u021bionat c\u0103 instrumentul este destul de flexibil \u0219i dispune de multe set\u0103ri. Astfel, cu ajutorul s\u0103u, po\u021bi crea lucr\u0103ri adaptate stilului unui artist specific sau pur \u0219i simplu po\u021bi experimenta cu ad\u0103ugarea rapid\u0103 a r\u0103s\u0103riturilor sau apusurilor. <\/p>\n

Dezvoltatorii sus\u021bin c\u0103 sistemul nu doar ia imagini de undeva, le combin\u0103 \u0219i ob\u021bine un rezultat. Nu, toate \u201eimagini\u201d ob\u021binute sunt generate. Adic\u0103 re\u021beaua neuronal\u0103 \u201ecreeaz\u0103\u201d ca un adev\u0103rat artist (sau chiar mai bine).<\/p>\n

P\u00e2n\u0103 acum, programul nu este disponibil liber, dar \u00een cur\u00e2nd va putea fi testat \u00een practic\u0103. Acest lucru se poate face la expozi\u021bia tehnologic\u0103 GPU Technology Conference 2019, care se desf\u0103\u0219oar\u0103 chiar acum \u00een California. C\u00e2\u021biva noroco\u0219i care au reu\u0219it s\u0103 participe la expozi\u021bie pot deja testa GauGAN.<\/p>\n

Re\u021bele neuronale sunt deja de mult timp antrenate s\u0103 participe \u00een procesul creativ. De exemplu, anul trecut, unele dintre ele au fost capabile s\u0103 creeze modele 3D<\/a><\/noindex>. \u00cen plus, dezvoltatorii de la DeepMind au \u00eenv\u0103\u021bat re\u021beaua neuronal\u0103 s\u0103 restaureze spa\u021bii \u0219i obiecte tridimensionale din desene, fotografii, schi\u021be. Pentru a recrea o figur\u0103 simpl\u0103, re\u021beaua neuronal\u0103 are nevoie de o singur\u0103 imagine, iar pentru a crea obiecte mai complexe sunt necesare cinci imagini pentru \u201eantrenare\u201d.<\/p>\n

\u00cen ceea ce prive\u0219te GauGAN, acest instrument va g\u0103si cu siguran\u021b\u0103 o aplicare comercial\u0103 demn\u0103 \u2014 multe domenii ale afacerii \u0219i \u0219tiin\u021bei au nevoie de astfel de servicii.<\/p>\n
