Imiyoboro isigaye
Imiyoboro isigaye (ResNets) numuyoboro wimbitse wongeyeho 'gusimbuka guhuza' kureka ibice biga guhinduka aho guhinduka byuzuye.
Incamake
This simple trick made it possible to train networks hundreds of layers deep, sparking a leap in image recognition accuracy.
Kwibira cyane
Mbere ya ResNets, gutondekanya ibice byinshi paradoxe ituma imiyoboro ikora nabi, ndetse no kumibare yamahugurwa, ikibazo cyitwa degradation. Muri 2015, Microsoft abashakashatsi Kaiming We na bagenzi be berekanye igisigisigi gisigaye: aho gusaba igipande cyibice kugirango gitange umusaruro H (x) mu buryo butaziguye, baretse bakiga kwiga ibisigisigi F (x) = H (x) - x, hanyuma bongeraho ibyinjijwe byumwimerere x inyuma binyuze muri shortcut. Niba urwego rudakenewe, rushobora kwiga gusa gukora ikintu (F (x) = 0). ResNet-152 yatsindiye amarushanwa ya ImageNet ya 2015 hamwe n'amakosa ya top-5 ya 3,6 ku ijana, yatsinze igereranyo cy’abantu, kandi imyubakire yacyo yabaye umusingi fatizo wo gutahura, gutandukanya, no gufata amashusho y’ubuvuzi.
Ubushishozi
Guhuza gusimbuka bihindura akazi ka buri gice muri y = F (x) + x. Mugihe cyo gusubira inyuma, icyiciro gitemba kinyuze mumirangamuntu idahindutse, ntigishobora rero gucika hafi ya zeru ndetse no mubice byinshi. Ibi bituma ibice byimbitse bitozwa. Indangamuntu ngufi ntizongereho ibipimo byinyongera; gusa iyo ibyinjijwe nibisohoka ingano ikora projection nto (1x1 convolution) ihindura ibipimo mbere yo kongerwaho.

Ihuriro risigaye ubu riri hafi-yisi yose: Abahindura, moderi yo gukwirakwiza, hamwe nururimi runini rwindimi zose zirazikoresha muguhagarika imyitozo yibice byimbitse. Ubushakashatsi burakomeje kubitandukanye nka pre-activation ResNets, inzira za ResNeXt zishyizwe hamwe, no guhuza ibitekerezo bisigaye n'amahugurwa asanzwe. Witegereze ihame rya skip-ihuza ihame ryogukomeza nkigice cyubatswe cyubatswe, nubwo inyubako zikikije zigenda ziva mubitekerezo byera bikerekeza kubitekerezo hamwe n'ibishushanyo mbonera.

Uburenganzira bwishusho hamwe no kwemererwa birashobora guhinduka ibyago byemewe n'amategeko niba ibimenyetso bidasobanutse.

What is Residual Networks?
Imiyoboro isigaye (ResNets) numuyoboro wimbitse wongeyeho 'gusimbuka guhuza' kureka ibice biga guhinduka aho guhinduka byuzuye. Aya mayeri yoroshye yatumye bishoboka guhugura imiyoboro amagana yimbitse, bitera gusimbuka muburyo bwo kumenya amashusho.
Ni ikihe kibazo amasano asigaye yakemuye byumwihariko?
Mbere ya ResNets, kongeramo ibice byinshi byateje ukuri kugabanuka no kumyitozo yamakuru. Kureka guhuza byakosowe mugukora ibice byoroshye guhitamo.
Ni ubuhe busigaye busigaye bubara nkibisohoka?
Guhagarika ibisigisigi bisohoka y = F (x) + x, wongeyeho ibisigisigi byize byinjijwe ukoresheje skip ihuza.
Kuki gusimbuka guhuza bifasha gradients mugihe cy'amahugurwa?
Indangamuntu ihita itanga inzira itaziguye ya gradients gutembera inyuma idahindutse, ikumira ikibazo cyo kubura-buhoro buhoro mubice byimbitse.
Hafi ya ResNet yatsindiye kuva muri 2015 yari ifite ibice bingahe?
ResNet-152, ifite ibice 152, yatsinze amarushanwa ya ImageNet 2015, yerekana ko imiyoboro yimbitse cyane ishobora gutozwa neza.
Niba ibice bisigaye byiga F (x) = 0, guhagarika gukora iki?
Iyo F (x) = 0, ibisohoka ni x gusa, bityo guhagarika bihinduka ikarita. Ibi bituma ibice byinyongera bitagira ingaruka niba bidakenewe.
