Ibicuruzwa bitandukanye
Kubogama kubogamye gusobanura impamvu icyitegererezo gishobora kunanirwa muburyo bworoshye cyangwa bukomeye.
Incamake
Kubogama kubogamye gusobanura impamvu icyitegererezo gishobora kunanirwa muburyo bworoshye cyangwa bukomeye. Nibibazo byingenzi hagati yinyuma idahwitse hamwe no gukabya, kandi kubibona neza byerekana niba moderi yawe ihuriweho namakuru mashya.
Bias-Variance Tradeoff yicaye mubikoresho bya AI. Iyo ubisobanukiwe, izindi ngingo za AI zoroha gusuzuma no kugereranya.
Kwibira cyane
Ikosa ryose ryo guhanura icyitegererezo gikora rishobora kugabanywamo ibice bitatu: kubogama, gutandukana, n urusaku rudashoboka. Kubogama ni ikosa riva mubitekerezo bidakwiye - icyitegererezo cyoroshye cyane kugirango gifate imiterere nyayo, nko guhuza umurongo ugororotse kumurongo (kudakwiye). Ibinyuranyo ni ikosa kuva sensibilité to sample yihariye y'icyitegererezo - icyitegererezo cyoroshye cyane gufata mu mutwe urusaku n'urusaku (birenze). Gufata nuko kumanura umwe bikunda kuzamura undi. Urwego rwohejuru rwa polinomial rugabanya kubogama ariko ibyahanuwe bihindagurika cyane na buri dataset nshya. Intego ntabwo ari ugukuraho ikosa ahubwo ni ugushaka ahantu heza aho igiteranyo cyabo - ikosa ryateganijwe ryose kumibare itagaragara - ni rito.
Ubushishozi
Ikigereranyo cyikizamini giteganijwe kirangirika nkuko Bias kwaduka wongeyeho Ibinyuranye wongeyeho ikosa ridasubirwaho. Nka moderi igoye izamuka, kubogama kugwa monotonike mugihe itandukaniro rizamuka, ritanga U-igeragezwa-ikosa ryo kugabanura byibuze byibuze byoroshye. Guhinduranya (nka L2 / ibihano bya ridge), gutema, no kugabanya ubujyakuzimu bwibiti nkana ongera nkana kubogama kugirango ugabanye itandukaniro. Uburyo bwa ensemble bukoresha imibare imwe: guterura impuzandengo yerekana moderi nyinshi zo murwego rwo hejuru kugirango zigabanye itandukaniro, mugihe kuzamura bigabanya kubogama mugukurikirana abiga intege nke.
Kumenya kubogama-Ibicuruzwa bitandukanye
Kugirango wubake byimbitse, fata Bias-Variance Tradeoff nkicyitegererezo gikora, ntabwo ari ikintu kimwe. Sobanura ibyagezweho, usobanure neza, kandi utandukanye ibyo sisitemu ishobora gukora byizewe nibisaba guca imanza zinzobere.
Mubimenyerezo, amakipe akomeye akoresha Bias-Variance Tradeoff yubaka icyitegererezo gikomeye, hanyuma agashushanya izo moderi kubibuza umusaruro. 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.
Iragufasha gutandukanya ibyifuzo bya tekiniki bisobanutse nururimi rwo kwamamaza. Igihe kimwe, Amakipe atandukanye arashobora gukoresha ijambo rimwe muburyo butandukanye, sobanura intera hakiri kare. 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.
