Warmup na Cosine Annealing Gahunda
Warmup yongerera buhoro igipimo cyo kwiga kuva kuri zeru mbere yimyitozo, hanyuma cosine annealing igabanuka neza ikamanuka ikurikira umurongo wa cosine.
Incamake
Together they stabilize early training and squeeze out better final accuracy, which is why nearly every modern transformer is trained this way.
Kwibira cyane
Iyo imyitozo itangiye, uburemere bwikitegererezo ntibisanzwe kandi gradients zirashobora kuba nini, bityo gusimbuka ugana ku gipimo kinini cyo kwiga akenshi bitera igihombo cyangwa gutandukana - cyane cyane hamwe na optimizatifike yo guhuza n'imihindagurikire y'ikirere nka Adam, ibigereranyo bitandukanye bikaba bitizewe mu ntambwe zambere. Warmup ikosora ibi mukongera umurongo igipimo hejuru yijana kugeza kuntambwe ibihumbi. Icyitegererezo kimaze guhagarara neza, cosine annealing ifata, ikabora igipimo nka 0.5 * (1 + cos (pi * t / T)) yo hejuru. Imiterere ya cosine ituma igipimo kiri hejuru hakiri kare kugirango iterambere ryihute, hanyuma ryorohe buhoro buhoro kugirango optimizer ibashe gutura byibuze byiza aho kuyizunguruka.
Ubushishozi
Cosine annealing ipima igipimo cyo kwiga kuri 0.5 * (1 + cos (pi * t / T)), aho t nintambwe igezweho naho T ni yose. Ibi bimara umwanya muremure hafi yikigereranyo, cyangirika vuba hagati, hanyuma kizingira hafi zeru kumpera - bitandukanye no kubora kumurongo ugororotse. Warmup mubisanzwe ni umurongo kandi mugufi. Gukomatanya umurongo bisa nkumusozi woroshye: hejuru, plateau-ish, hanyuma kunyerera byoroshye kugeza kuri zeru.

Kazoza ka Warmup na Cosine Annealing Gahunda
Warmup-plus-cosine ikomeza kuba resept yuburyo bwururimi runini, ariko impinduka zirakwirakwira. Warmup-itajegajega-yangirika (WSD) igumana igipimo gihoraho hanyuma ikangirika cyane kurangiza, bigatuma byoroha kwagura kwiruka utabanje gusaba uburebure bwagenwe. Abashakashatsi barimo kwiga kandi impamvu ubushyuhe bukora - kubihuza n’urusaku rugenda rwiyongera hamwe n’igihombo-nyaburanga kigabanuka - hamwe n’ibikoresho bigenda byiyongera-byerekana ubushyuhe bwo hejuru hamwe nigipimo cyo hejuru, bikagabanya ikigeragezo-nikosa ryiganje muri iki gihe.

What is Warmup and Cosine Annealing Schedules?
Warmup yongerera buhoro igipimo cyo kwiga kuva kuri zeru mbere yimyitozo, hanyuma cosine annealing igabanuka neza ikamanuka ikurikira umurongo wa cosine. Hamwe na hamwe bahindura imyitozo hakiri kare kandi bagakuramo neza neza neza, niyo mpamvu hafi ya transformateur igezweho yatojwe murubu buryo.
Niyihe ntego nyamukuru yicyiciro cyo gushyushya mugitangira imyitozo?
Guhera ku kigero kinini cyo kwiga ku bipimo bitunguranye birashobora gutera igihombo cyangwa gutandukana, bityo ubushyuhe bugabanya umuvuduko witonze kugirango intambwe zambere zihamye.
Cosine annealing igabanya igipimo cyo kwiga ukurikije ubuhe buryo?
Igipimo gipimwa na 0.5 * (1 + cos (pi * t / T)), gitanga umusozi woroshye uguma hejuru hakiri kare kandi ukanyerera kugeza kuri zeru.
Ninde optimizer yunguka cyane kubushuhe kuko igereranya ryayo ritizerana hakiri kare?
Ikigereranyo cya Adam yiruka kigereranya gishingiye kuburugero ruto cyane muntambwe yambere, bigatuma intambwe yintambwe igaragara idahwitse - ubushyuhe bugabanya ibi.
Muri cosine formula, T igereranya iki?
T ni horizon hejuru igipimo cyangirika kuva hejuru kugeza kuri zeru; t ni intambwe iriho muri iyo horizon.
Ni izihe nyungu imwe yo gushyuha-gutuza-kwangirika (WSD) hejuru ya cosine-ndende?
WSD ifata igipimo gihoraho noneho ikangirika cyane kurangiza, bityo urashobora gukomeza icyiciro gihamye kigenda kirekire kandi ugahitamo aho uhagarara nyuma.
