Nibura Bayes Risk Decoding
Impanuka ya Bayes Risk (MBR) itoranya ibisohoka bisa cyane nibindi byinshi bishoboka, aho kuba kimwe gishoboka cyane.
Incamake
It optimizes for the quality metric you actually care about instead of raw likelihood.
Kwibira cyane
Kode ya decode isanzwe ikurikirana cyane (ikigereranyo cya MAP), ariko interuro ishoboka cyane ntabwo akenshi ari nziza ukurikije ibipimo byabantu cyangwa ibipimo. MBR decoding ivugurura intego: hitamo umukandida ugabanya 'ibyago,' aho ibyago ari kimwe ukuyemo ibipimo bisa (nka BLEU, COMET, cyangwa BERTScore) ugereranije nibindi bisubizo byerekana. Mu myitozo utanga icyitegererezo cy'abakandida, hanyuma kuri buri mukandida ubare impuzandengo yacyo isa nabandi bose; umukandida ufite amasezerano yo hejuru aringaniye aratsinda. Mu buryo bwimbitse, MBR ihitamo ibyumvikanyweho ibyo gukwirakwiza icyitegererezo hamwe, gushungura flukes. Yatanze inyungu zikomeye muguhindura imashini no kuvuga mu ncamake, cyane cyane iyo ihujwe nubuziranenge bwibipimo byiza nka COMET nkibikorwa byingirakamaro.
Ubushishozi
Mubisanzwe, MBR ihitamo argmax hejuru yabakandida bateganijwe gukoreshwa, E [u (umukandida, reference)], aho ikwirakwizwa ryagereranijwe na hypotheses. Kuberako ibyukuri byukuri bitazwi, icyuzi kimwe cyatanzwe gikora nka pseudo-references. Igiciro ni quadratic: kugereranya abakandida N muburyo bubiri ni O (N kwaduka) guhamagarwa metric, niyo mpamvu MBR ikora neza ikoresha ihuriro, gukata neza-gukata, cyangwa kugereranya ibikorwa byingirakamaro.

Kazoza Kutagira Inyanja Ntoya
Hamwe n'ibipimo byize nka COMET na MetricX, MBR ubu ikubita inshuro zishakisha ibisobanuro kubisobanuro, ubushakashatsi rero bwibanda kubigiciro bihendutse: gutema abakandida bashingiye ku cyizere, kongera kubara, no guhindura MBR mumahugurwa yicyitegererezo hakoreshejwe disillation kuburyo inzira imwe yihuta yigana ibyo MBR yahisemo. Tegereza uburyo bwa MBR bwatoranijwe kugirango bikwirakwize mubitekerezo, aho gutoranya iminyururu myinshi no guhitamo ibisubizo byumvikanyweho cyane byerekana ihame rimwe.

What is Minimum Bayes Risk Decoding?
Impanuka ya Bayes Risk (MBR) itoranya ibisohoka bisa cyane nibindi byinshi bishoboka, aho kuba kimwe gishoboka cyane. Ihindura ibipimo byiza witaho mubyukuri aho kuba bishoboka.
Niki decoding ya MBR ihitamo aho kugirango ikurikirane imwe ishoboka?
MBR itoranya umukandida yerekana inyungu ziteganijwe (kugabanya ingaruka) ugereranije nibindi byitegererezo byerekana umusaruro, ntabwo ari umukandida wa MAP.
Ko ibyukuri byukuri bitaboneka, MBR ikoresha iki nka pseudo-references?
MBR igereranya ikwirakwizwa ryayo hamwe na hypothesse yayo bwite, ugereranije buri mukandida na pisine isigaye.
Kuki naive MBR ibarwa ihenze?
Gutanga amanota kuri buri mukandida ku bandi bakandida bapimye inshuro enye, gushishikarizwa gutema no guhuriza hamwe kugabanya ibiciro.
Nibihe bikoresho byingirakamaro byatumye MBR ikomera cyane muguhindura imashini?
Ibipimo bya Neural nka COMET bifitanye isano neza nubucamanza bwabantu, kandi kubikoresha nkibikoresho bya MBR akenshi bikubita gushakisha.
