Kumamodeli okusabalalisa afana ne-Stable Diffusion, ingena esikhundleni sokwaziswa okungenalutho okusetshenziswe ekuqondisweni kwamahhala kwe-classifier, ngakho-ke sonke isinyathelo sokwenza umsindo siyasuswa kuleyo ncazelo. Izaziso ezingezinhle zinikeza abasebenzisi i-lever eqondile phezu kwezinto ezingafunwa, kodwa zisebenza kuphela kumamodeli asebenzisa isiqondiso sangempela samahhala sokuhlukanisa isigaba, futhi angakwazi ukuphindisela lapho esetshenziswe ngokweqile.
I-Deep Dive
Amamodeli okusabalalisa adala isithombe ngokuqala emsindweni ongahleliwe futhi asisuse ngezinyathelo eziningi. Esinyathelweni ngasinye, imodeli ibikezela umsindo kabili: uma ubekwe esimweni ekwazisweni kwakho futhi kanye kokokufaka 'okungenamibandela', ngokuvamile ukwaziswa okungenalutho. Isiqondiso esingena-Classifier, esethulwe ngu-Jonathan Ho no-Tim Salimans, sihlanganisa kokubili. Iqala ekuqaguleni okungenamibandela futhi iqhubekele phambili iye kwesinemibandela, ikalwa ngesilinganiso sokuqondisa (esivame ukubizwa ngokuthi CFG). Umphumela ulandela ukwaziswa eduze kakhulu kunemodeli eluhlaza. Umyalo ophikisayo uvele umiselele umyalezo ongenalutho esikhundleni sombhalo wakho ophikayo. Ifomula manje isunduzela kude encazelweni engeyinhle njengoba iya kwephozithivu. Yingakho ukwaziswa okunegethivu kungesona isihlungi noma isinyathelo sangemva kokucubungula: silolonga sonke isinyathelo sokwenza umsindo. Indlela yasabalala ngamathuluzi omphakathi afana ne-AUTOMATIC1111 web interface ngo-2022. Yaduma kakhulu nge-Stable Diffusion 2.x, imiphumela yayo abasebenzisi abaningi abayithola ithuthuke ngokuphawulekayo ngama-negative. Izaziso ezingezinhle zisebenza kangcono emicabangweni ebonakalayo ebonakalayo imodeli eyazi kahle: 'ukufiphala', 'umbhalo', 'i-watermark', 'i-monochrome', noma umbala noma into ethile. Zisebenza kancane njengezilungiso ezingabonakali. Kumamodeli amaningi enhloso evamile, amagama anjengokuthi 'imvelo embi' noma 'iminwe eyengeziwe' ngokuvamile enza okuncane, ngoba lawo mamodeli ayengavamile ukubona amagama-ncazo achaza ukwehluleka okunjalo. Bangenza futhi imiphumela ibe mibi kakhulu. Uhlu olude luphusha isithombe sisuke ezindleleni eziningi ngesikhathi esisodwa. Lokho kunganciphisa ukuhlukahluka, kugeze noma kugcwale imibala, futhi kukhiqize ukwakheka okuqinile, futhi izikali zokuqondisa eziphezulu zikhulisa umphumela. Amanye amamodeli, afaka amamodeli we-distilled kanye nezinyathelo ezimbalwa, eqa ukudlula okungenamibandela ngokuphelele. Kulezo, iziyalezo ezingezinhle azinakwa ngaphandle uma ithuluzi livula i-CFG yangempela, ebambezela ukukhiqizwa. Umbono oyiphutha ovamile ukuthi ukubhala 'akukho kati' ekwazisweni okuyinhloko akubandakanyi amakati. Izifaki khodi zombhalo ziphatha ukunganaki kahle, ngakho-ke umusho ungangeza amakati esikhundleni salokho.
I-Strategic Impact
Isivinini nesikali
I-Visual AI ingakwazi ukuhlola, ukutholwa, nokumaka imisebenzi esikalini.
Yakha ukukhetha
Amathimba aqanjiwe angakwazi ukulinganisa imiqondo ngokushesha ngezibuyekezo ezimbalwa ezenziwa mathupha.
Ithimba kanye nokusebenza komsebenzi
Imisebenzi ingasebenzisa amasiginali wesithombe nawevidiyo obekunzima ukuwenza ngaphambilini.
Ikusasa Lemibono Emibi Esizukulwaneni Sezithombe
Ukwaziswa okungekuhle kuya ngokuya kuncipha njengoba amamodeli ethuthuka. Amasistimu amasha anamakhodi ombhalo anamandla alandela imiyalo enemininingwane emihle ngokwethembeka, futhi amamodeli agaywe ngesiqondiso ayeka ukwesekwa okulungile okungalungile ukuze athole isivinini. Ngaleso sikhathi, ucwaningo luyaqhubeka ezindleleni zokuqondisa ezinikeza ukulawula okungcono ngaphandle kwemiphumela engemihle ye-CFG esobala, futhi ezinye izindawo zokusebenzelana zinikeza izilawuli ezihlukene zokucindezela izinto ezinjengombhalo noma isitayela. Isifundo esihlala njalo sabasebenzi siwumshini: hlola ukuthi ingabe imodeli yakho isebenzisa igatsha elibi, gcina ama-negative amafushane futhi aqinile, futhi uhlole ithemu ngayinye usebenzisa imbewu engaguquki ukuze ubone ukuthi ishintsha ini ngempela.
Ukuqaliswa Komhlaba Wangempela
Umthwebuli wezithombe womkhiqizo okhiqiza isithombe sewashi lesi studio wengeza 'umbhalo, i-watermark, ilogo' njengesaziso esibi ukuze angakhuthazi ukumaketha okungelona iqiniso ngemuva.
Umdwebi wezithombe ofuna umdwebo womugqa ohlanzekile ubeka 'i-shading, color, photorealistic' ekwazisweni okungekuhle. Ukubhala 'akukho shading' ekwazisweni okuyinhloko esikhundleni salokho kungangeza ukufiphaza ngephutha.
Umsebenzisi unamathisele umyalo ophikisayo wesikhathi esingu-60 okopishwe kuforamu futhi athole ukuthi izithombe ziba sicaba futhi ziphindaphindeka. Ukuyiphungula kumatemu ambalwa aqondisiwe kubuyisela okuhlukile.
Othile ushintshela kumodeli egayiwe futhi abone ukuthi inkambu yokwaziswa engalungile ayenzi lutho, ngoba ngokuzenzakalela imodeli ayilokothi ibale isibikezelo sesibili ukwaziswa okunegethivu okungaphakelwa.
Izingozi & Guardrails
Amalungelo ezithombe kanye nemvume kungaba ubungozi bezomthetho uma ukuvela kungacacile.
Ukusebenza kwemodeli kungahluka kukho konke ukukhanya, izibalo zabantu, kanye nezindawo.
Okuhle okungelona iqiniso kungase kungabonakali ngaphandle uma izinga lokuzethemba liqashelwa.
Ukuqalisa Umhlahlandlela
Chaza indlela yokwamukela yokunemba, ukukhumbula, nezindleko zamaphutha.
Hlola ngedatha efana nezimo zangempela zokukhiqiza.
Engeza isibuyekezo somuntu ukuze uthole ukuzethemba okuphansi noma izibikezelo zomthelela omkhulu.
Landelela ukukhukhuleka kwemodeli bese uqinisekisa kabusha ngemva kwezinguquko zekhamera noma zesethi yedatha.

Imibuzo evame ukubuzwa
Kuyini ukwaziswa okungekuhle esizukulwaneni sesithombe?
Ukwaziswa okungekuhle umbhalo ochaza lokho ongakufuni esithombeni esenziwe nge-AI. Kumamodeli okusabalalisa afana ne-Stable Diffusion, ingena esikhundleni sokwaziswa okungenalutho okusetshenziswe ekuqondisweni kwamahhala kwe-classifier, ngakho-ke sonke isinyathelo sokwenza umsindo siyasuswa kuleyo ncazelo. Izaziso ezingezinhle zinikeza abasebenzisi i-lever eqondile phezu kwezinto ezingafunwa, kodwa zisebenza kuphela kumamodeli asebenzisa isiqondiso sangempela samahhala sokuhlukanisa isigaba, futhi angakwazi ukuphindisela lapho esetshenziswe ngokweqile.
Esiqondisweni esingena-classifier, yini eshintshwayo engafanele esikhundleni?
I-CFG ivamise ukuqhathanisa isibikezelo esitshelwayo nesibikezelo esivela ekwazisweni okungenalutho. Ukwaziswa okunegethivu kuthatha indawo yokwaziswa okungenalutho, ngakho isiqondiso siyaphusha kulowo mbhalo.
Kungani ukubhala 'akukho kati' ekwazisweni okuyinhloko kungase kukhiqize amakati?
Isifaki khodi sibhalisa 'amakati' njengomqondo oqinile futhi sigeja kakhulu u-'cha'. Ukuhambisa igama ekwazisweni okuphambene kubuyisela emuva isiqondiso.
Kungani isiqondiso samahhala esilinganisa isigaba sicishe siphindwe kabili isibalo sesinyathelo ngasinye?
Isinyathelo ngasinye sidinga ukuqagela komsindo okubili, okukodwa kokwaziswa ngakunye, futhi kuhlanganiswe kusetshenziswa isikali sokuqondisa.
Ngokusho komhlahlandlela, yiliphi igama elibi okungenzeka libe nomphumela oqinile, onokwethenjelwa?
Okubi kusebenza kangcono emiqondweni ebonakalayo ebonakalayo imodeli eyazi kahle. Ama-watermark avela ezithombeni eziningi zokuqeqesha, kuyilapho izincazelo zokuhluleka ezifana 'ne-bad anatomy' zingavamile ukuvela kumagama-ncazo avamile.
Kwenzekani uma usebenzisa ukwaziswa okungekuhle ngemodeli egayiwe yokuqondisa eyeqa ukudlula okungenamibandela?
Njengoba lingekho igatsha elingenamibandela noma elinegethivu elizobalwa, umbhalo ophikayo awunandawo ongaya kuyo. Ukuvula i-CFG yeqiniso kuyibuyisela ngenani lesivinini.
