Uhlolojikelele
Ividiyo ye-Imagen iyisistimu ka-Google ka-2022 yokuthumela umbhalo kuye kuvidiyo eyakha isiqeshana ngenqwaba yamamodeli ayisikhombisa okusabalalisa, ngalinye lingeza ozimele abaningi noma ukulungiswa okuningi. Kubalulekile ngoba kubonise ukuthi ukunqwabelanisa izigaba ezikhethekile kungakhiqiza kanjani ukucaca okuphezulu, ividiyo eshelelayo yesikhashana kusuka ekwazisweni okukodwa.
I-Imagen Video Cascades ingeyokugeleza komsebenzi okubonwa ngekhompyutha okuhumusha noma okukhiqiza imidiya ebonakalayo ukuze ihlaziywe, isebenze, futhi isungule.
I-Deep Dive
Ividiyo ye-Imagen, eyethulwe ngu-Google Ucwaningo ngo-Okthoba 2022, lunweba indlela ye-Imagen yokuguqula umbhalo uye esithombeni ekunyakazeni. Isishumeki esiqandisiwe sombhalo we-T5 siphendula ukwaziswa kube ukushumeka kolimi okunothile okubeka isimo ngasinye. Imodeli yokusabalalisa isisekelo iqala ikhiqize ividiyo encane, enesilinganiso esiphansi, bese i-cascade yamamodeli ayisithupha e-diffusion ishintshana yenze ukulungiswa okuphezulu kwesikhashana (kwengeza ozimele phakathi kwalaba abakhona) kanye nokulungiswa okuphezulu kwendawo (ukukhula kwephikseli kokulungiswa). Ipayipi eligcwele eliphumayo licishe libe yividiyo engu-1280x768 kumafreyimu angu-24 ngomzuzwana, amasekhondi ambalwa ubude. Ngenxa yokuthi ukuqonda okujulile kolimi kuhlala kusishumeki sombhalo, Ividiyo ye-Imagen inganikeza umbhalo onesitayela ofundekayo, ubuhle bobuciko obuhlukahlukene, nokunyakaza kwento eqaphela i-3D, okubonisa ukuthi amabhithi esiteji acophelelayo azama ukwenza yonke into ngemodeli eyodwa enkulu.
I-Technical Insight
I-cascade ihlukanisa isizukulwane esinzima kakhulu sibe yizinkinga ezincane ezilawulekayo. Amamodeli okusabalalisa ayisikhombisa agijima ngokulandelana: i-base generator eyodwa kanye namamodeli amathathu esikhashana kanye namamodeli amathathu esikhashana angcono kakhulu. Ngayinye ibekwe esimweni sokushumeka ngokushesha kanye nokuphumayo kwesigaba sangaphambilini. Amasu afana ne-v-prediction parameterization kanye ne-progressive distillation kuyasheshisa ukusampula, kuyilapho isiqondiso samahhala se-classifier siqinisa ukubambelela ngokushesha kuzo zonke izigaba zeketango.
I-Mastering Imagen Video Cascades
Ividiyo ye-Imagen iyisistimu ka-Google ka-2022 yokuthumela umbhalo kuye kuvidiyo eyakha isiqeshana ngenqwaba yamamodeli ayisikhombisa okusabalalisa, ngalinye lingeza ozimele abaningi noma ukulungiswa okuningi. Kubalulekile ngoba kubonise ukuthi ukunqwabelanisa izigaba ezikhethekile kungakhiqiza kanjani ukucaca okuphezulu, ividiyo eshelelayo yesikhashana kusuka ekwazisweni okukodwa. I-Imagen Video Cascades ingeyokugeleza komsebenzi okubonwa ngekhompyutha okuhumusha noma okukhiqiza imidiya ebonakalayo ukuze ihlaziywe, isebenze, futhi isungule. Ukuze wakhe ukuqonda okujulile, phatha i-Imagen Video Cascades njengemodeli yokusebenza, hhayi isici esisodwa: chaza imiphumela efiselekayo, ucacise ukucabanga, futhi uhlukanise lokho isistimu engakwenza ngokwethembeka kulokho okusadinga ukwahlulela kochwepheshe.
Empeleni, amaqembu aqinile asebenzisa ibhalansi ye-Imagen Video Cascades namaqiniso okusebenza njengekhwalithi yedatha, ukuhluka kokukhanya, nokuvumelana kwamalebula. Babhala imibandela yempumelelo ecacile, ukuhlola okuqhathaniswa nedatha engokoqobo nokugeleza komsebenzi, futhi baphindaphinde ngokusekelwe kumaphethini okuhluleka aqashiwe esikhundleni sokuwina kwebhentshimakhi yesikhathi esisodwa. Yilapho ukuqonda kwethiyori kuguquka kube amandla ahlala njalo kuwo wonke umkhiqizo, inqubomgomo, kanye nokusebenza.
I-Visual AI ingakwazi ukuhlola, ukutholwa, nokumaka imisebenzi esikalini. Ngesikhathi esifanayo, amalungelo ezithombe kanye nemvume kungaba ubungozi bomthetho uma ukutholakala kungacacile. Indlela eqine kakhulu iwukuhlanganisa isivinini sokuhlola nesiyalo sokuphatha: qhuba abashayeli bezindiza, bamba ubufakazi, ushicilele amalogi ezinqumo, futhi ubuyekeze izivikelo ngokuqhubekayo njengoba imodeli yokuziphatha, okulindelwe ngabasebenzisi, kanye nezimfuneko zokulawula zishintsha.
