Incamake
Igihombo cyibanze nigikorwa cyahinduwe cyo gutakaza uburemere-buremereye ingero zoroshye kuburyo detector ishobora kwibanda kubintu bikomeye, bidasanzwe. Byakemuye ibyakabije bikabije-nibintu-bitaringaniza byamugaye icyiciro kimwe.
Igihombo Cyibanze Kutamenya Kuringaniza nububiko bwa tekiniki bugira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo.
Kwibira cyane
Mugushakisha ibintu, ishusho irashobora kuba irimo ibintu bike gusa ariko ibihumbi icumi byabakandida, hafi ya byose byoroshye. Hamwe na cross-entropie isanzwe, uyu mwuzure wibintu byoroshye byiganje kuri gradient kandi urohama ibyiza bidasanzwe. Igihombo cyibanze, cyatangijwe mu mpapuro za RetinaNet 2017 na Lin na bagenzi be kuri Facebook AI, gikosora ibi mugwiza cross-entropy kubintu (1 - p_t) ^ gamma. Iyo icyitegererezo cyashyizwe mubyizere kandi neza, p_t iri hafi ya 1, bityo ibintu bigabanuka kuri zeru kandi urugero rwiza rwatanze umusanzu. Ingero zikomeye, zidahwitse zigumana hafi-yuzuye uburemere. Hamwe na gamma hafi 2, RetinaNet yahuye cyangwa ikubita buhoro buhoro ibyiciro bibiri byihuta nka Faster R-CNN mugihe ugumye umuyoboro woroheje.
Ubushishozi
Ibyibanze byibanze gamma igenzura uburyo ingero zoroshye zahagaritswe: kuri gamma 0 igihombo cyibanze gihwanye na cross-entropy isanzwe, kandi gamma yo hejuru ikarishye kwibanda kubibazo bikomeye. Kuringaniza uburemere alfa (akenshi 0,25 kubiciro bidasanzwe) mubisanzwe bihujwe nayo. By'umwihariko ibintu bihindura imiterere ya gradients, ntabwo ari agaciro k'igihombo gusa, kubwibyo gusubiranamo mubisanzwe byibanda kuburugero rudasobanutse nta ntoki zikomeye-ubucukuzi bw'amabuye y'agaciro cyangwa gusubiramo.
Kumenya Igihombo Cyibanze Kumenyekanisha Kuringaniza
Igihombo cyibanze nigikorwa cyahinduwe cyo gutakaza uburemere-buremereye ingero zoroshye kuburyo detector ishobora kwibanda kubintu bikomeye, bidasanzwe. Byakemuye ibyakabije bikabije-nibintu-bitaringaniza byamugaye icyiciro kimwe. Igihombo Cyibanze Kutamenya Kuringaniza nububiko bwa tekiniki bugira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo. Kugirango wubake ubushishozi bwimbitse, fata igihombo cyibanze kubutagereranywa nkicyitegererezo gikora, ntabwo ari ikintu kimwe: gusobanura ibyagezweho, gusobanura ibitekerezo, no gutandukanya ibyo sisitemu ishobora gukora byizewe nibisaba guca imanza zinzobere.
Mubimenyerezo, amakipe akomeye akoresha Focal Loss for Imbalanced Detection atezimbere 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.
