Incamake
Adam ni akazi keza cyane inyuma yimiyoboro myinshi igezweho, ihita ihuza igipimo cyo kwiga kuri buri kintu cyose. Nibyingenzi kuko ituma imyitozo yimbitse yihuta kandi ntigabanuke cyane kuruta kumanuka gahoro gahoro.
Adam na Adaptive Optimizers nigikoresho cya tekiniki cyubaka kigira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo.
Kwibira cyane
Adam (Adaptive Moment Estimation), yatangijwe na Kingma na Ba muri 2014, ihuza ibitekerezo bibiri. Ubwa mbere, umuvuduko: ituma impuzandengo yangirika yikigereranyo cya gradients zashize (umwanya wambere) bityo ivugurura ryubaka umuvuduko mubyerekezo bihamye. Icya kabiri, kuri buri kintu gipima: ikurikirana impuzandengo ya gradiyo ya kare (umwanya wa kabiri) kandi igabanya buri ntambwe kumuzi ya kare ya gaciro, bityo ibipimo hamwe nini nini, urusaku rufata intambwe ntoya kandi gake ivugururwa ifata intambwe nini. Guhuza n'imihindagurikire y'ikirere bivuze ko ushobora gukoresha igipimo kimwe cyo kwiga kumurongo wose. Impinduka, AdamW, ikuramo uburemere bwangirika kuva buhoro buhoro kandi byabaye nkibisanzwe byo guhugura impinduka nini nicyitegererezo cyururimi.
Ubushishozi
Adam agumana impuzandengo ebyiri zo kwiruka kuri buri kintu: m (gradients) na v (kwaduka kwaduka), ivugururwa nigipimo cyangirika beta1 (mubisanzwe 0.9) na beta2 (mubisanzwe 0,999). Kuberako byombi bitangirira kuri zeru, babogamye-bakosowe no kugabana na (1 - beta ^ t). Ivugurura ni theta = theta - lr * m_hat / (sqrt (v_hat) + epsilon), aho epsilon (hafi 1e-8) irinda kugabana na zeru. Niyo mpamvu Adamu akeneye kwiga bike-igipimo cyo kugereranya ugereranije na SGD isanzwe.
Kumenya Adamu na Optimizers
Adam ni akazi keza cyane inyuma yimiyoboro myinshi igezweho, ihita ihuza igipimo cyo kwiga kuri buri kintu cyose. Nibyingenzi kuko ituma imyitozo yimbitse yihuta kandi ntigabanuke cyane kuruta kumanuka gahoro gahoro. Adam na Adaptive Optimizers nigikoresho cya tekiniki cyubaka kigira ingaruka kumiterere yicyitegererezo, igiciro cyibikorwa remezo, ubukererwe, no kwizerwa mubipimo. Kugirango wubake byimbitse, fata Adam na Adaptive Optimizers 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 Adam na Adaptive Optimizers 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.
