Uhlolojikelele
Ukulahleka kwe-triplet kufundisa inethiwekhi ye-neural ukubeka izinto ezifanayo eduze nezinto ezingafani ziqhelelene endaweni yokushumeka. Kuyisisekelo esingemuva kokuqashelwa kobuso, ukusesha izithombe, namasistimu wokuncoma adinga ukuqhathanisa izinto kunokumane azihlukanise.
I-Triplet Loss kanye ne-Metric Learning kuhlezi kukhithi yamathuluzi eyinhloko ye-AI. Uma uyiqonda, ezinye izihloko ze-AI ziba lula ukuzihlola nokuqhathanisa.
I-Deep Dive
Ukufunda kwemethrikhi kuqeqesha imodeli ukuthi ikhiqize okushumekiwe, ama-vector lapho ibanga libonisa ukufana. Ukulahleka kukathathu kwenza lokhu kusetshenziswa okokufaka okuthathu ngesikhathi: ihange, iphozithivu (isigaba esifanayo nesikhonkwane), kanye nenegethivu (isigaba esihlukile). Umgomo uphusha ihange eduze kwephozithivu kunenegethivu okungenani ngemajini egxilile. Ngokusemthethweni, ukulahlekelwa ngu-max(0, d(a,p) - d(a,n) + margin), lapho u-d ngokuvamile eyibanga le-Euclidean. I-FaceNet ka-Google ka-2015 yenze le ndlela yaduma, ifunda ukushumeka kobuso obungu-128-dimensional ngqo. Uma usuqeqeshiwe, uqhathanisa noma yiziphi izinto ezimbili ngokubala ibanga, akukho ukuqeqeshwa kabusha okudingekayo kobunikazi obusha. Leli khono lesethi evulekile yingakho amandla okufunda emethrikhi eqinisekisa futhi ukuhlukaniswa kwemisebenzi yokubuyisa kungakwazi ukuphatha kalula.
I-Technical Insight
Imajini yiyona eyenza ukulahlekelwa kathathu kusebenze. Ngaphandle kwayo, imodeli ingabhidliza kancane konke okushumekiwe kuye endaweni eyodwa, kwenze lonke ibanga libe uziro noku-oda kungasho lutho. Imajini iphoqelela isilondolozi: inegethivu kufanele okungenani ibe imajini ibe kude kunephozithivu ngaphambi kokuba ukulahlekelwa kufinyelele kuziro. Ukushumeka kuvamise ukwenziwa kwe-L2 ku-hypersphere yeyunithi, ngakho amabanga ahlala elinganiselwe futhi eqhathaniswa. Ukukhetha imajini (imvamisa cishe ku-0.2) kuhwebelana ngokuthi izigaba zihlangana kanjani ngokumelene nokuhlukana phakathi kwazo.
Ukufundisa Ukulahlekelwa Okuthathu kanye nokufunda kwe-Metric
Ukulahleka kwe-triplet kufundisa inethiwekhi ye-neural ukubeka izinto ezifanayo eduze nezinto ezingafani ziqhelelene endaweni yokushumeka. Kuyisisekelo esingemuva kokuqashelwa kobuso, ukusesha izithombe, namasistimu wokuncoma adinga ukuqhathanisa izinto kunokumane azihlukanise. I-Triplet Loss kanye ne-Metric Learning kuhlezi kukhithi yamathuluzi eyinhloko ye-AI. Uma uyiqonda, ezinye izihloko ze-AI ziba lula ukuzihlola nokuqhathanisa. Ukuze wakhe ukuqonda okujulile, phatha i-Triplet Loss and Metric Learning njengemodeli yokusebenza, hhayi isici esisodwa: chaza imiphumela efiselekayo, ucacise ukucabanga, futhi uhlukanise lokho isistimu engakwenza ngokwethembeka kulokho okusadinga ukwahlulela kochwepheshe.
Empeleni, amaqembu aqinile asebenzisa i-Triplet Loss kanye ne-Metric Learning akha amamodeli emicabango aqinile kuqala, bese ebeka imephu lawo mamodeli emikhawulweni yokukhiqiza yangempela. Babhala imibandela yempumelelo ecacile, ukuhlola okuqhathaniswa nedatha engokoqobo nokugeleza komsebenzi, futhi baphindaphinde ngokusekelwe kumaphethini okuhluleka aqashiwe esikhundleni sokuwina kwebhentshimakhi yesikhathi esisodwa. Yilapho ukuqonda kwethiyori kuguquka kube amandla ahlala njalo kuwo wonke umkhiqizo, inqubomgomo, kanye nokusebenza.
Kukusiza ukuthi uhlukanise izimangalo ezicacile zobuchwepheshe kusukela olimini lokumaketha. Ngesikhathi esifanayo, amaqembu ahlukene angasebenzisa igama elifanayo ngokuhlukile, ngakho chaza ububanzi kusenesikhathi. Indlela eqine kakhulu iwukuhlanganisa isivinini sokuhlola nesiyalo sokuphatha: qhuba abashayeli bezindiza, bamba ubufakazi, ushicilele amalogi ezinqumo, futhi ubuyekeze izivikelo ngokuqhubekayo njengoba imodeli yokuziphatha, okulindelwe ngabasebenzisi, kanye nezimfuneko zokulawula zishintsha.
