Incamake
InfoNCE nigihombo gitandukanye cyigisha icyitegererezo cyo gukurura bibiri bihuye hamwe no gusunika byombi bidahuye mugushira umwanya. SimCLR ni urwego rwibanze rwakoresheje iki gihombo kugirango wige amashusho akomeye uhereye kumibare itanditse, irwanya kugenzurwa.
InfoNCE na SimCLR Intego ninzitizi yubaka tekinike igira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo.
Kwibira cyane
InfoNCE (Urusaku-Itandukaniro Rigereranya Kumakuru Yamakuru) itoza kodegisi kugirango ikibazo nibyiza byukuri bifite amanota asa cyane kuruta ikibazo nibibi byinshi. Nubusanzwe ni softmax cross-entropy hejuru yamanota asa: kuri ankeri, ibyiza bigomba gutsinda ibibi. SimCLR (2020) yakoresheje ibi kumashusho: fata ishusho imwe, shyiramo ibyongeweho bibiri bidasanzwe kugirango ukore couple nziza, ukoreshe byombi ukoresheje kodegisi isangiwe wongeyeho umutwe wa projection, kandi ukoreshe ubushyuhe busanzwe bwapimye cross-entropy (NT-Xent, impinduka ya InfoNCE) kuburyo ibitekerezo byombi byiyongereye bikurura mugihe andi mashusho yose mugice akora nkibibi. SimCLR yerekanye ko kongera amakuru gukomeye, umutwe uteganijwe utagira umurongo, ingano nini yicyiciro, hamwe nubushyuhe bwahujwe hamwe reka reka moderi yiyobora ihure nabashinzwe kugenzura kuri ImageNet - nta kirango na kimwe mugihe cyo kwitegura.
Ubushishozi
NT-Xent ibara cosine isa hagati ya L2-isanzwe yashyizwemo, igabanywa nubushyuhe τ, kandi ikoresha softmax cross-entropy ifata ibyiza nkicyiciro gikwiye murugero rwose. Hasi τ ityaza isaranganya kandi ihana ibibi bikomeye. Umutwe wa SimCLR (MLP) ukoreshwa gusa mugihe cyo kwitegura no kujugunywa nyuma - guhagararirwa mbere yo kwimura umutwe neza. Ibice binini bifite akamaro kuko bitanga ibibi byinshi murwego rumwe.
Kumenya AmakuruNCE na SimCLR Intego
InfoNCE nigihombo gitandukanye cyigisha icyitegererezo cyo gukurura bibiri bihuye hamwe no gusunika byombi bidahuye mugushira umwanya. SimCLR ni urwego rwibanze rwakoresheje iki gihombo kugirango wige amashusho akomeye uhereye kumibare itanditse, irwanya kugenzurwa. InfoNCE na SimCLR Intego ninzitizi yubaka tekinike igira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo. Kugirango wubake byimbitse, fata InfoNCE na SimCLR Intego nkicyitegererezo gikora, ntabwo ari ikintu kimwe: gusobanura ibyagezweho, gusobanura ibitekerezo, no gutandukanya ibyo sisitemu ishobora gukora byizewe nibisaba guca imanza zinzobere.
Mu myitozo, amakipe akomeye akoresha InfoNCE na SimCLR Intego zitezimbere ubwubatsi, amakuru, hamwe nibikorwa remezo birwanya kwizerwa nigiciro. Bandika ibipimo ngenderwaho byerekana intsinzi, bagerageza kurwanya amakuru afatika hamwe nakazi keza, kandi bagasubiramo bashingiye kubikorwa byagaragaye ko batsinzwe aho gutsinda inshuro imwe. Aha niho imyumvire yubumenyi ihinduka mubushobozi burambye kubicuruzwa, politiki, nibikorwa.
Ibyemezo byubwubatsi bitwara imikorere nigiciro cyimikorere kumyaka. Mugihe kimwe, Guhindura igipimo kimwe gishobora guhisha intege nke za sisitemu. Uburyo bukomeye cyane ni uguhuza umuvuduko wikigereranyo hamwe na disipuline yimiyoborere: kuyobora abaderevu, gufata ibimenyetso, gutangaza ibyemezo byicyemezo, no gukomeza kuvugurura uburyo bwo kwirinda nkimyitwarire yicyitegererezo, ibyo abakoresha bategereje, nibisabwa n'amategeko bigenda bihinduka.
