Imiyoboro ya Siamese hamwe nigihombo cya gatatu
Imiyoboro ya Siamese ikoresha amashami abiri cyangwa menshi asa, agabana ibiro kugirango yige uburyo inyongeramusaruro ebyiri zisa, aho gutondekanya buri kimwe.
Incamake
Triplet loss trains them by pulling matching items together and pushing mismatches apart, which is the backbone of face recognition, signature verification, and one-shot learning.
Kwibira cyane
Umuyoboro wa Siamese ukoresha buri cyinjijwe unyuze kuri kodegisi imwe hamwe nuburemere busangiwe, itanga icyerekezo cya buri kimwe. Aho guhanura ikirango cyicyiciro, igereranya gushiramo ukoresheje intera nka Euclidean cyangwa cosine. Ibi bituma sisitemu imenya ibyiciro bishya itigeze itoza - byingenzi mugihe ufite ingero imwe cyangwa nkeya kuriranga (kwiga rimwe). Impapuro zambere zakoresheje igihombo gitandukanya kubiri (bisa nibidasa). Igihombo cya gatatu cyatezimbere ibi mumahugurwa kubintu bitatu icyarimwe: inanga, icyiza (icyiciro kimwe na ankeri), nicyiza (icyiciro gitandukanye). Intego ihatira intera nziza-nziza kuba ntoya kuruta intera-ya-intera itandukanijwe, bityo icyitegererezo cyiga umwanya wo gushiramo aho ibintu bimwe biranga ibintu byegeranye kandi indangamuntu zitandukanye ziguma kure.
Ubushishozi
Igihombo cya gatatu ni kinini (0, d (a, p) - d (a, n) + margin), aho d ari intera, a / p / n ni inanga / nziza / mbi, kandi margin ni icyuho gihamye. Niba ibibi bimaze kuba kure bihagije, igihombo ni zeru kandi ntakintu na kimwe cyigishijwe - bityo imyitozo yubuziranenge ishingiye ku bucukuzi bukomeye: guhitamo inyabutatu aho ibibi byegereye uburiganya hafi ya ankeri. Kugabana ibiro hejuru yamashami byemeza ikarita yinjiza ikarita mumwanya umwe wo gushyiramo, aribyo bituma kugereranya intera bifite ireme.
Ingaruka z'Ingamba
Igiciro na bije
Ibyemezo byubwubatsi bitwara imikorere nigiciro cyimikorere kumyaka.
Ibyemezo bisobanutse
Ubuhanga bwa tekinike bufasha amakipe guhitamo umurongo ukwiye, ntabwo ari shyashya gusa.
Kugenzura ubuziranenge
Guhitamo neza bya injeniyeri bigabanya ibintu byizewe mubikorwa.
Ejo hazaza h'imiyoboro ya Siamese no gutakaza gatatu
Igitekerezo cyibanze - wige umwanya ushiramo aho intera ihwanye - ubu itwara imyigire minini itandukanye yo kwiga. Uburyo nka SimCLR hamwe na moderi nka CLIP bihuriza hamwe ihame rimwe miriyoni y'amashusho hamwe na jambo zombi nta butatu bweruye. Tegereza imyigire yubumenyi kugirango ikomeze kuba iyambere mugushakisha, kugabanywa, kugirwa inama, no gushakisha vector-base base, mugihe igihombo gishya (InfoNCE, byinshi-bisa) hamwe nitsinda rinini bigenda bisimbuza intoki zacukuwe muntoki kugirango zikore neza kandi zipime.
Gushyira mu bikorwa Isi
Kumenyekanisha isura kuri terefone (Imisusire ya FaceNet): kugenzura indangamuntu ukareba niba gushiramo amasura abiri yegeranye bihagije.
Kugenzura umukono no kwandika intoki, byemeza niba icyitegererezo gihuye na dosiye.
Kwigana no hafi-kwigana, gushakisha amafoto yibicuruzwa bisa cyangwa amashusho yibye.
Kwiga inshuro imwe kubyiciro bidasanzwe, kumenya umuntu mushya cyangwa ikintu uhereye kurugero rumwe rwanditse.
Ingaruka & Kurinda
Gutezimbere igipimo kimwe gishobora guhisha intege nke za sisitemu.
Ibikorwa Remezo no kubungabunga akenshi usanga bidahabwa agaciro.
Icyuho cyumutekano no kwitegereza birashobora kwiyongera uko sisitemu igenda igorana.
Igishushanyo mbonera
Sobanura ubukererwe, ubuziranenge, nigiciro cyibiciro mbere yo kubishyira mubikorwa.
Ibipimo byerekana umutwaro ufatika hamwe namakuru yimiterere.
Gukurikirana ibikoresho kubikosa, drift, ningaruka zabakoresha.

Igihombo cya gatatu gikoresha inanga, icyiza (icyiciro kimwe) nicyiza (icyiciro gitandukanye) kugirango ushireho umwanya.
Intego yo gutakaza inshuro eshatu ishyira mubikorwa iki?
Igihombo gisunika icyiza hafi yicyiza byibuze margin, ikomatanya ibintu bimwe-hamwe.
Ni ukubera iki 'ubucukuzi bw'amabuye y'agaciro' ari ingenzi mu mahugurwa yo gutakaza gatatu?
Niba ibibi bimaze kuba kure, igihombo ni zeru; guhitamo uburiganya gufunga ibibi biha icyitegererezo ikintu gifatika cyo kwiga.
