Momwe Mphaka Amasinthira Kusakanikirana Kokhazikika (2023)

Mu imodzi mwa nkhani zosayembekezereka zomwe sizinachitike m'mbiri ya AI, mphaka wapanyumba mosadziwa anathandiza mainjiniya kuzindikira kusokonekera kwamalo kosawoneka bwino kwapaipi yopangira zithunzi za Stable Diffusion. Chochitika cha 2023 chidakhala phunziro lodziwika bwino la momwe zinthu zosayembekezereka zenizeni zimatha kuwulula zolakwika zomwe maola masauzande ambiri akuphonya mokhazikika.

Kodi Chidachitika Ndi Chiyani Ndi Mphaka Ndi Kusokonezeka Kokhazikika?

Kumayambiriro kwa 2023, injiniya wophunzirira makina omwe amagwira ntchito kunyumba adawona china chachilendo. Mphaka wawo, atadutsa pa kiyibodi panthawi yophunzitsira ya Stable Diffusion, adabweretsa mndandanda wa zilembo zopanda pake mu batch yachangu. M'malo motulutsa zinthu zosokonekera kapena kuponya zolakwika, chojambulacho chinapanga zithunzi zingapo zokhala ndi mawonekedwe osasinthika - mawonekedwe a tessellation obwerezabwereza omwe sakanayenera kukhalapo potengera kulowetsa mwachangu.

Ichi sichinali chaphokoso chongochitika mwachisawawa. Chitsanzocho chinavumbulutsa tsankho lomwe silinadziwike m'magawo achitsanzo, makamaka momwe zomangamanga za U-Net zidasinthira zophatikizira zina zomwe zidatuluka kunja kwa malire achilankhulo. Kuphatikizika kwa kiyibodi kwa mphaka kudapangitsa kuti pakhale chidziwitso chotsutsa chomwe palibe woyesa munthu yemwe adaganizapo kuyesa, kuwonetsa zolakwika pakuphatikizika kwa ma encoder amtundu wa CLIP zomwe zidakhudza momwe maubwenzi amalo amawerengedwera panthawi yosokoneza.

Gulu la mainjiniya linakhala masabata otsatirawa likutsatira zomwe zidayambitsa: nkhani yoyandama mumndandanda wazinthu zobisika zomwe zimangowonekera pansi pa ma tokenization. Kukonzaku kwapititsa patsogolo kulumikizana kwazithunzi pamitundu yonse yofulumira ndi pafupifupi 3-4%, phindu lalikulu pakugwirira ntchito kwa AI.

Nchifukwa Chiyani Zolowa Zosavomerezeka Zimagwira Ziphuphu Zomwe Magulu a QA Amaphonya?

Kuyesa kokhazikika kumatsata malingaliro amunthu. Mainjiniya amalemba mayeso potengera zomwe amayembekeza ogwiritsa ntchito, momwe angaganizire, ndi mitundu yolephera yodziwika kuchokera kumayendedwe am'mbuyomu. Koma mapulogalamu - makamaka machitidwe a AI okhala ndi mabiliyoni a magawo - ali ndi kuphulika kophatikizana kwa mayiko omwe angatheke omwe palibe njira yoyesera yomwe ingathe kuphimba.

"Nsikidzi zowopsa kwambiri sizomwe zimabisala mu code yomwe simunayese. Ndizomwe zimabisala mu code yomwe mudayesa ndi malingaliro olakwika." — Mfundo imeneyi, yomwe imamveka kwa nthawi yayitali muumisiri wamapulogalamu akale, imakhala yofunika kwambiri pamakina ophunzirira makina pomwe malo olowetsamo amakhala opanda malire.

Zochitika za mphaka zalimbitsa zomwe akatswiri opanga chipwirikiti akhala akudziwa kwa zaka zambiri: zongochitika mwachisawawa, zosayembekezereka zimawulula zofooka zadongosolo zomwe kuyesa kwadongosolo sikungathe. Ndilo mfundo yomweyi kumbuyo kwa kuyesa kwa fuzz, komwe deta yolakwika mwadala imalowetsedwa m'makina kuti awulule zovuta. Chosiyana apa chinali chakuti fuzzer inali ndi miyendo inayi ndi mchira.

Kodi Izi Zawulula Chiyani Zokhudza Mavuto Ochotsa AI?

Kuthetsa zolakwika zamitundu ya AI ndizosiyana kwambiri ndi mapulogalamu achikhalidwe. Ntchito wamba ikalephera, mumapeza chipika cholakwika, kusakatula, njira yobwereketsa. Mtundu wa AI ukatulutsa zolakwitsa mobisa, kulephera kumatha kuzindikirika kwa miyezi ingapo chifukwa palibe yankho limodzi "lolondola" lofananiza.

• Kusawoneka bwino kwa danga: Zoyimira mkati mwamitundu yofananira ndizovuta kutanthauzira, zomwe zimapangitsa kuti zikhale zovuta kutsata zomwe zidapangidwa kuti zibwerere ku zolakwika zinazake.
• Kumverera mwachangu: Zosintha pang'ono pamawu atha kutulutsa zotulutsa zosiyanasiyana, zomwe zikutanthauza kuti zolakwika zitha kupezeka pamikhalidwe yopapatiza komanso yosayembekezereka.
• Kuyesa kumvera: Mosiyana ndi ntchito zamagawidwe zolondola zoyezeka, mtundu wa kupanga zithunzi umakhala wokhazikika pang'ono, zomwe zimaloleza kuwonongeka kosawoneka bwino kuti kulowe m'macheke a makina.
• Zodalira pa: Kulakwitsa kumodzi kokha mu encoder ya mawu kumatha kufalikira kudzera munjira yolumikizirana, ndandanda ya denoising, ndi VAE decoder, zomwe zimapangitsa kusanthula kwa mizu kukhala kovuta kwambiri.
• Kuphatikizika kwa data pamaphunziro: Kusiyanitsa pakati pa zolakwika pamapangidwe achitsanzo ndi kukondera komwe kumachokera ku data yamaphunziro kumafuna maphunziro osamala omwe amatenga nthawi komanso okwera mtengo kwambiri.

Kodi Chochitika Ichi Chakhudza Bwanji Kachitidwe ka AI?

Nkhani yothetsa vuto la mphaka, ngakhale ili yoseketsa pamwamba, idapangitsa masinthidwe angapo a momwe magulu a AI amayendera kutsimikizika kwabwino. Mabungwe angapo akulitsa ma protocol awo oyesa ma fuzz amitundu yopangira, makamaka kuphatikizira ma tokeni osasinthika komanso otsutsana omwe amatsanzira zosagwirizana ndi chilankhulo. Magulu ena tsopano akuyendetsa zoyerekeza za "keyboard walk" monga gawo la mapaipi awo ophatikizika mosalekeza.

Zochitikazi zidalimbikitsanso chidwi pazida zomasulira zamitundu yosiyanasiyana. Ngati zojambulazo zikadakhala zosadziwikiratu - kusintha kwamitundu kosawoneka bwino m'malo molimba mtima - zikadakhala zosazindikirika mpaka kalekale. Izi zapangitsa kuti anthu ammudzi akhazikitse njira zodziwikiratu zomwe zakhala zikuyenda bwino, makina omwe amatha kuwonetsa zolakwika za kawerengetsedwe ngakhale zithunzi zimawoneka ngati zabwinobwino.

Kwa magulu omwe amayang'anira kayendetsedwe ka ntchito movutikira pakukula kwa AI, kubwereza kwazinthu, komanso kutsimikizika kwamtundu, zochitika ngati izi zikuwonetsa kufunikira kwa mawonekedwe apakati. Vuto likadutsa pa makina ojambulira mawu, chokonzera ndandanda, ndi makina ojambulira, kutsatira kafukufuku pazida zomwazika ndi njira zoyankhulirana zosalumikizidwa kumapangitsa kuti pakhale mikangano.

Mafunso Ofunsidwa Kawirikawiri

Kodi vuto la Stable Diffusion cat linali chochitika chenicheni?

Nkhani yayikulu imachokera ku akaunti yogawidwa kwambiri yochokera ku gulu la akatswiri a AI mu 2023. Ngakhale kuti zenizeni zakhala zongopeka pofotokozanso, zochitika zaukadaulo - kuyika kwa kiyibodi mwachisawawa powonetsa cholakwika cham'mlengalenga - ndi zolembedwa bwino komanso zimagwirizana ndi njira zolephereka zodziwika pamapangidwe amitundu yofananira. Zina mwangozi zomwezi zachitika m'mbiri yonse ya uinjiniya wa mapulogalamu.

Kodi kuyesa kwa fuzz kungagwire nsikidzi mumitundu yamtundu wa AI?

Kuyesa kwa fuzz kumakhala kothandiza pozindikira mitundu ina ya nsikidzi, makamaka zokhudzana ndi kachulukidwe kazinthu, ma tokenization m'mphepete, komanso kusakhazikika kwa manambala. Komabe, si chipolopolo chasiliva cha AI yopangira. Chifukwa zitsanzozi zimapanga zotulukapo zongoyerekeza m'malo mongotsimikizira, kufotokozera zomwe zimatchedwa "kulephera" panthawi yoyesa fuzz kumafuna njira zamakono zodziwira zolakwika m'malo mongongonena kuti zadutsa/zolephera.

Kodi magulu a akatswiri a AI amatha bwanji kukonza zolakwika pamakina ovuta?

Magulu ambiri a AI okhwima amadalira njira zotsatirira zoyeserera, kudula mitengo pakati, zolemba zogwirira ntchito, komanso kasamalidwe kolongosoka. Chovuta chachikulu ndikusunga kutsatiridwa - kulumikiza zida zinazake ku mtundu wachitsanzo, deta yophunzitsira, ma hyperparameter, ndi ma code omwe adapanga. Magulu omwe amaphatikiza machitidwewa kukhala machitidwe ogwirizana amathera nthawi yocheperako pakuchita zinthu mopitilira muyeso komanso nthawi yochulukirapo pakuthana ndi zovuta zenizeni.

Chepetsani Kuvuta Kwanu Kantchito

Kaya mukukonza ma AI kapena mukuwongolera mabizinesi ena ovuta, zida zogawika zimapanga kuganiza mogawikana. Mewayz imabweretsa ma module ophatikizika 207 mubizinesi imodzi yodalirika ndi ogwiritsa ntchito opitilira 138,000 - kupatsa gulu lanu mawonekedwe apakati ofunikira kuti afufuze zovuta komwe amachokera, kugwirizanitsa mayankho, ndikuyenda mwachangu. Yambitsani kuyesa kwanu kwaulere pa app.mewayz.com ndikuwona momwe magwiridwe antchito amamvekera.
