Incamake
Kugereranya Ibiro bya Stochastic (SWA) bifata impuzandengo yoroheje yuburemere bwikitegererezo kuva kumanota menshi yatinze mumyitozo aho gukomeza gufata ifoto yanyuma. Aya mayeri ahendutse akenshi yerekana icyitegererezo muburyo bushimishije, mugari mugace k'igihombo, gikunda kuba rusange muburyo bugaragara kumibare itagaragara.
Kugereranya Ibiro bya Stochastique ni inyubako ya tekiniki yubaka igira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo.
Kwibira cyane
SWA yatangijwe na Izmailov, Wilson na bagenzi be mu 2018, SWA ikoresha uburyo bwo kubona ko SGD ifite igipimo gihoraho cyangwa cyikurikiranya cyiga idahinduka ku ngingo imwe - irazunguruka ikikije ikibaya kinini, kiringaniye. Aho gutoranya imwe muri izo ngingo zihagarika urusaku, SWA ikoresha igipimo cyo hejuru cyo hejuru (akenshi gihoraho cyangwa cyikurikiranya) cyo kwiga mugihe cyanyuma kandi ugereranije uburemere busura, mubisanzwe buri gihe. Impuzandengo yikigereranyo yicaye hafi yakarere kegeranye. Kuberako ibyiciro-bisanzwe bisanzwe bibarwa kuburemere bwihariye, SWA isaba inzira imwe yinyongera imbere yamakuru kugirango ibaze uburyo BN ikoresha nuburyo butandukanye kuri moderi yagereranijwe. Igiciro ni ubuntu, kandi inyungu zuzuye zirahuza mumashusho yatondekanye ndetse no hanze yacyo.
Ubushishozi
SWA ikomeza ikigereranyo cyo gukora w_SWA = (n · w_SWA + w_i) / (n + 1) yavuguruye buri cyiciro, mugihe moderi ya SGD nzima ikomeza gushakisha hamwe nigipimo kinini cyo kwiga. Ugereranije muburemere bugereranya ensemble mumwanya wimikorere ariko igura icyitegererezo kimwe mubisobanuro, ntabwo ari byinshi. Uburyo bwingenzi ni uko minima iringaniye ifite imbaraga zo guhagarika ibiro, bityo imyitozo / gutakaza ibizamini bigumaho, bikagabanya icyuho rusange.
Kumenya Ibiro Bikomeye
Kugereranya Ibiro bya Stochastic (SWA) bifata impuzandengo yoroheje yuburemere bwikitegererezo kuva kumanota menshi yatinze mumyitozo aho gukomeza gufata ifoto yanyuma. Aya mayeri ahendutse akenshi yerekana icyitegererezo muburyo bushimishije, mugari mugace k'igihombo, gikunda kuba rusange muburyo bugaragara kumibare itagaragara. Kugereranya Ibiro bya Stochastique ni inyubako ya tekiniki yubaka igira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo. Kugirango wubake byimbitse, fata uburemere buringaniye bwa Stochastic nk'icyitegererezo gikora, ntabwo ari ikintu kimwe: gusobanura ibyagezweho, gusobanura ibitekerezo, no gutandukanya ibyo sisitemu ishobora gukora byizewe nibisaba guca imanza zinzobere.
Mubimenyerezo, amakipe akomeye akoresha Stochastic Weight Averaging ahindura imyubakire, 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.
