Gutakaza inshuro eshatu no Kwiga Ibipimo
Igihombo cya gatatu cyigisha urusobe rushyira ibintu bisa hafi hamwe nibintu bidasa kure mumwanya wo gushiramo.
Incamake
It is the foundation behind face recognition, image search, and recommendation systems that need to compare things rather than just classify them.
Kwibira cyane
Kwiga Metricike bitoza icyitegererezo cyo kubyara, ibice aho intera igereranya. Igihombo cya gatatu gikora ibi ukoresheje inyongeramusaruro icyarimwe: inanga, icyiza (icyiciro kimwe na ankeri), nibibi (ibyiciro bitandukanye). Intego isunika inanga hafi yicyiza kuruta ibibi byibuze intera ihamye. Mubisanzwe, igihombo ni kinini (0, d (a, p) - d (a, n) + margin), aho d ubusanzwe intera ya Euclidea. __AIU_PROTECTED_11 __ ya 2015 FaceNet yamamaje ubu buryo, yiga gushiramo isura-128. Umaze gutozwa, ugereranya ibintu bibiri ukoresheje intera yo kubara, nta kongera imyitozo ikenewe kubiranga bishya. Ubu bushobozi bwo gufungura ni impamvu yo kwiga imbaraga zo kwiga kugenzura no kugarura imirimo itondekanya ntishobora gukemura byoroshye.
Ubushishozi
Impera niyo ituma igihombo cya gatatu gikora. Bitabaye ibyo, icyitegererezo gishobora gusenyuka buhoro buhoro ibyashizwe kumurongo umwe, bigatuma intera yose zeru no gutondeka ntacyo bivuze. Impera ihatira buffer: ibibi bigomba kuba byibuze margin kure kuruta ibyiza mbere yuko igihombo kigera kuri zeru. Ibishushanyo mubisanzwe L2-isanzwe kuri hypersphere, bityo intera iguma imipaka kandi igereranywa. Guhitamo margin (akenshi hafi 0.2) bigurisha uburyo amasomo akomeye arwanya gutandukana hagati yabo.

Ejo hazaza h'igihombo cya gatatu no Kwiga Metric
Igihombo cyinyabutatu cyasimbuwe cyane nintego zagutse nkibintu byinshi bisa, porokisi-inanga, hamwe nigihombo gitandukanye (InfoNCE) igereranya ibice byinshi kuri buri ntambwe kandi bigahinduka vuba. Uburyo bwigenga bwonyine nka SimCLR bwerekana metric yiga irashobora gukora idafite ibirango ifata ibitekerezo byongeweho nkibyiza. Nka vector base base hamwe no kugarura-byongerewe ibisekuru byiyongera, wize gushira ushimangira gushakisha ibisobanuro kuri miliyari-yibintu, bityo igitekerezo cyibanze cyo intera-nki-kigenda gihinduka hagati, nubwo uburyo bwihariye butatu bugenda bugabanuka.
Gushyira mu bikorwa Isi
Kugenzura isura ya FaceNet: terefone n'amarembo ya pasiporo byemeza umwirondoro mugenzura niba ibyapa bibiri byo mumaso bigwa mumipaka.
Gushakisha ibicuruzwa biboneka: imbuga za e-ubucuruzi zireka abaguzi bashireho ifoto hanyuma bagarure ibintu bisa nkibintu byegereye umuturanyi ushyiramo gushakisha.
Kugenzura abavuga: abafasha amajwi bashizemo icyitegererezo cyijwi bakagereranya numwirondoro wanditse kugirango wemeze uvuga.

What is Triplet Loss and Metric Learning?
Igihombo cya gatatu cyigisha urusobe rushyira ibintu bisa hafi hamwe nibintu bidasa kure mumwanya wo gushiramo. Nishingiro ryihishe inyuma yo kumenyekanisha isura, gushakisha amashusho, hamwe na sisitemu yo gutanga ibyifuzo bigomba kugereranya ibintu aho kubishyira mubyiciro gusa.
Ni ubuhe butumwa butatu bugize butatu mugutakaza gatatu?
Inyabutatu igizwe na ankeri, nziza isangira icyiciro cya ankeri, nibibi biva mubyiciro bitandukanye.
Kuki gutakaza inshuro eshatu birimo ijambo margin?
Hatariho intera, icyitegererezo gishobora gushushanya ibintu byose kumurongo umwe, bigatuma intera zose zeru kandi byoroshye guhaza igihombo. Impera ihatira gutandukana nyabyo.
Nubuhe buryo buzwi bwa 2015 bwamamaye gutakaza inshuro eshatu kugirango tumenye isura?
__AIU_PROTECTED_11 __ 'FaceNet yakoresheje igihombo cya gatatu kugirango yige gushira hamwe no gushyiraho igipimo cyo kugenzura isura.
Niki cyamenyerejwe metric-yiga icyitegererezo gisohoka kuri buri cyinjijwe?
Icyitegererezo cyerekana ikarita yinjiza ibice; noneho ugereranya ibintu mugupima intera iri hagati yabyo.
Kuki kwiga metric bikwiranye nibibazo byafunguye nko kongeramo amasura mashya?
Kuberako kumenyekanisha gushingiye ku gushyiramo intera, urashobora kwandikisha indangamuntu nshya ubitse gusa, nta moderi yo kongera imyitozo isabwa.
