Intera ya Fréchet Intera
Intera ya Fréchet Intera (FID) ni igipimo gisanzwe cyo gusuzuma uburyo bufatika kandi butandukanye bwerekana amashusho yakozwe.
Incamake
It compares the statistics of real and generated images in a deep feature space — lower scores mean the fakes look closer to the real thing.
Kwibira cyane
FID, yatangijwe na Heusel n'abandi. muri 2017, yakosoye inenge yingenzi mumanota yatangijwe: ntabwo yigeze igereranya amashusho yakozwe namakuru nyayo. FID igaburira amashusho nyayo kandi yakozwe binyuze mumurongo wateguwe wa Inception-v3 kandi igasoma ibice 2048-byerekana imiterere ya vector kuva murwego rwimbitse kuri buri shusho. Hanyuma irerekana buri cyiciro cyibiranga nka Gaussian itandukanye, ikabivuga muri make hamwe na materique ya covariance. Intera iri hagati yabanya Gaussiya ibarwa hamwe nintera ya Fréchet (nanone yitwa intera ya 2-Wasserstein). FID yo hepfo isobanura ibyagabanijwe kubyara bivuze kandi ikwirakwiza bihuye neza namashusho nyayo, ifata ubudahemuka (birasa nkukuri?) Nubudasa (bikubiyemo amakuru atandukanye?).
Ubushishozi
Inzira ya FID ni itandukaniro rya kwaduka ya bibiri bisobanura ibice byongeweho hamwe na (igiteranyo cya covariances ukuyemo kabiri matrix kare kare yibicuruzwa byabo). Kuberako ikoresha covariance yuzuye, FID ihana ibisubizo bidasobanutse, ibisubizo bidashoboka hamwe nuburyo bwo gusenyuka aho icyitegererezo gitanga ibintu bike cyane. Nibyoroshye kubunini bw'icyitegererezo - amashusho make cyane kubogama kugereranya hejuru - kubwibyo abimenyereza mubisanzwe babara amashusho ibihumbi icumi, akenshi 50.000.

Umuvuduko n'igipimo
AI igaragara irashobora gukora igenzura, gutahura, no gutondekanya imirimo kurwego.
Build choices
Amakipe arema arashobora prototype ibitekerezo byihuse hamwe nintoki nkeya.
Itsinda hamwe nakazi
Ibikorwa birashobora gukoresha amashusho nibimenyetso bya videwo byari bigoye gutunganya.
Kazoza ka Fréchet Intangiriro Intera
FID ikomeza kuba ikibanza kidasanzwe, ariko intege nke zayo zitwara ubundi buryo. Abashakashatsi berekanye ko iragwa kubogama kwa ImageNet kuva Inception-v3 kandi ntibashobora kutemeranya nubucamanza bwabantu, bigatuma ibipimo nka FID bibarwa kubiranga CLIP (rimwe na rimwe byitwa FDD cyangwa CMMD), Intera ya Kernel Intangiriro (KID) kuburugero ruto, hamwe nuburinganire / kwibutsa ibipimo bitandukanya ubudahemuka nubudasa. Witegereze ubukire, ibiranga-umugongo-agnostic hamwe no kugereranya guhuza isuzuma, cyane cyane nk'inyandiko-ku-shusho hamwe na videwo yerekana amashusho arenga umubare umwe w'incamake.
Gushyira mu bikorwa Isi
Ibipimo bya GAN nka StyleGAN, aho amakipe atangaza FID kuri datasets nka FFHQ kugirango agereranye ubuziranenge bwibisekuruza.
Gukurikirana imyitozo yiterambere rya moderi yo gukwirakwiza kubara FID kuri bariyeri kugirango urebe igihe ubwiza bwibishusho buhagaze neza.
Ugereranije guhatanira inyandiko-ku-shusho yerekana kuri dataset ya COCO, aho FID yo hepfo ivugwa nkibimenyetso byerekana umusaruro ushimishije.
Gutahura uburyo bwo gusenyuka muri generator, kuva igihe covariance ya FID izamuka mugihe icyitegererezo gitanga amashusho make cyane.
Ingaruka & Kurinda
Uburenganzira bwishusho hamwe no kwemererwa birashobora guhinduka ibyago byemewe n'amategeko niba ibimenyetso bidasobanutse.
Imikorere yicyitegererezo irashobora gutandukana kumurika, demografiya, nibidukikije.
Ibyiza byibinyoma birashobora kutamenyekana keretse niba ibyiringiro byateganijwe bikurikiranwa.
Igishushanyo mbonera
Sobanura ibipimo byo kwemererwa kugiciro, kwibutsa, nibiciro byamakosa.
Gerageza hamwe namakuru ajyanye nuburyo nyabwo bwo gukora.
Ongeraho isubiramo ryabantu kubwizere buke cyangwa guhanura cyane.
Kurikirana icyitegererezo cya drift hanyuma uhindurwe nyuma ya kamera cyangwa dataset ihinduka.

What is Fréchet Inception Distance?
Intera ya Fréchet Intera (FID) ni igipimo gisanzwe cyo gusuzuma uburyo bufatika kandi butandukanye bwerekana amashusho yakozwe. Iragereranya imibare yamashusho nyayo kandi yakozwe mumwanya wimbitse - amanota yo hasi bivuze ko impimbano isa hafi yikintu gifatika.
Amanota yo hasi ya FID yerekana iki?
FID ipima intera iri hagati yikintu nyacyo kandi cyabyaye kugabanwa, bityo agaciro gake bivuze ko ibyashizweho byakozwe bihuza cyane namakuru yukuri mubwizerwa no gutandukana.
Nuwuhe muyoboro wateganijwe FID ikoresha mugukuramo ibiranga amashusho?
FID inyuza amashusho binyuze mumurongo wateguwe na Inception-v3 kandi ikoresha 2048-yuburinganire bwa pisine-layer yibiranga amashusho nyayo kandi yakozwe.
Nigute FID ivuga muri make buri shusho yibiranga amashusho mbere yo kubigereranya?
Buri kintu cyashyizweho kigereranywa nkikinyamanswa kinini, kandi FID ibara intera ya Fréchet (2-Wasserstein) hagati ya ba Gaussiya bombi.
Ni ubuhe butumwa bukomeye bw'amanota yatangiriye FID yakemuye?
Amanota yo gutangira yasuzumye gusa amashusho yakozwe mu bwigunge; FID yateye imbere kuri yo ugereranije mu buryo butaziguye no gutanga amashusho nyayo.
Kuki FID izamuka mugihe generator ifite ikibazo cyo gusenyuka?
FID ikoresha covariance yuzuye yibiranga, iyo rero moderi itanga ibintu bike cyane ikwirakwizwa ryayo itandukana namakuru nyayo, igasunika amanota hejuru.
