Byagenze bite
Abashakashatsi Chengkuo Bian na Pengcheng Xie berekana urwego rwo gusobanura impamvu imiyoboro ya nete-nete itanga ibisubizo bidahuye muburyo bwiza bwo gukora neza. Icapiro ryabo ryerekana ibintu bitatu: uruhare rwa surrogate, umuturanyi wizewe, nuburyo iterambere ryibanze ryogutezimbere rishobora gutera.
Icapiro ryashyikirijwe arXiv ku ya 25 Kanama risuzuma ikibazo cyagarutsweho mu kwiga imashini ifashwa no gutezimbere: imitekerereze ya neural surrogate rimwe na rimwe igabanya umubare w’isuzuma rihenze, ariko mu bindi bice bituma imikorere idahinduka cyangwa ikarushaho kuba mbi. Abanditsi bavuga ko uku kwivuguruza kugaragara gusobanurwa n’ibintu bitatu aho gusobanurwa neza gusa. Uru rupapuro rwibanze ku gukuramo ibidafite ishingiro, aho ishakisha ibisubizo byiza idakoresheje mu buryo butaziguye ibikomoka ku bikorwa bifatika.
Imiterere ya mbere ireba uruhare rwa surrogate. Ukurikije ibisobanuro, icyitegererezo cyize ni ingirakamaro mugihe gitanze amanota y'abakandida ko intego nyayo igikora kandi ikanemeza. Nibyangiza iyo isimbuye gradient uburyo bwo gutezimbere bushingiye. Abanditsi bashizeho iri tandukaniro bavuga ko bagerageza ibintu mugihe bafite icyiciro cya surrogate, umuyoboro wamahugurwa, nuburyo bwibanze bwashyizweho. Inkomoko ntisobanura ubwo buryo cyangwa uburyo muburyo bukurikira.
Ikintu cya kabiri nicyagatatu bireba ahantu hamwe nicyumba kiboneka. Icyitegererezo cyatojwe munzira nziza cyasobanuwe nkicyizere gusa imbere yumupaka, hamwe nikosa ryacyo ntirizimira mugihe abaturanyi bagabanutse cyangwa bagakomeza kwizerwa uko yaguka. Abanditsi bavuga kandi ko surrogate ishobora kwihutisha iterambere gusa uburyo bwibanze bugishoboye gukora. Bavuga ko ingero 117 zagaragaye, aho ubufasha bwarinze umutekano bwatumye umubare ukemurwa neza kugeza kuri 67 ukagera kuri 84. Ibinyuranye n’uko, gusimbuza buhoro buhoro byagabanije ibisubizo bigera kuri 65. Ibivugwa kandi bivuga ko kuvana igihe cyagenwe mu gihombo cy’amahugurwa byagabanije kwemererwa kuva kuri 0.703 bikagera kuri 0.148.

Impamvu ari ngombwa
Akazi gatanga umuburo ufatika wo kwirinda amahugurwa neza nkigipimo gihagije cyingirakamaro. Mubipimo byabanditsi, ubufasha bwa surrogate burinzwe bwongereye umubare wibisubizo nyabyo bivuye kuri 67 bigera kuri 84 kuri 117, mugihe gusimbuza gradients byagabanije ibisubizo kuri 65.
Urupapuro rwibanze rwibanze ni ugusuzuma: biha abimenyereza uburyo bwo kubaza igihe igereranya ry’imitsi rishobora gufasha mbere yo kubifata nkumusimbura rusange kubintu byiza. Itandukaniro riri hagati yo gusaba abakandida no gusimbuza gradients ningaruka cyane cyane kuko icyitegererezo kimwe cyize gishobora kugira ingaruka zitandukanye bitewe nuburyo gihuza numuti. Ibisubizo byatangajwe byerekana ko igishushanyo mbonera gishobora kugira akamaro nkicyitegererezo gikwiye.
Ibipimo ngenderwaho byerekana ingaruka zishobora kuba byibuze byibuze byageragejwe. Kwimuka uva kuri 67 ukagera kuri 84 ibisubizo bihanitse byukuri mubihe 117 ni impinduka nini kuruta guhinduranya gato, ukurikije ibisobanuro. Impinduka zavuzwe ko zemewe-zivuye, kuva 0.703 kugeza 0.148 nyuma yo gukuraho igihembwe cyamahugurwa ajyanye na gradient, kimwe nacyo gishyigikira abanditsi bavuga ko intego y'amahugurwa igira ingaruka niba nyirubwite azakoresha surrogate. Ibi nibisabwa na progaramu, ntabwo bigenzuwe byigenga.
Imipaka nayo ni ngombwa. Ibisobanuro ntibivuga uko ingero 117 zatoranijwe, icyo "ubunyangamugayo buhanitse" bivuze, ibigeragezo bingahe byakorewe kurugero, cyangwa niba iterambere ryarageragejwe mu mibare. Ntabwo kandi ishyiraho ko imiyoboro yimitsi iruta iyindi mikorere ya surrogate, ko uburyo bukora muri sisitemu yumusaruro, cyangwa ko bugabanya ibiciro byukuri kwisi muri rusange. Inkomoko ivuga ko iniverisite ya Monte Carlo aho gusana interineti yakira byari bifite agaciro ka 10.40 mugihe ibiciro bya surrogate byonyine byari bifite 0.00, bishimangira ko impinduka zishyirwa mubikorwa zishobora kuba zifite agaciro kuruta kongeramo icyitegererezo cyize.

Ibyo kureba
Ibyavuye mu bushakashatsi byaturutse ku nyandiko imwe yatanzwe kandi ibisobanuro byayo ntibisobanura ibipimo ngenderwaho, uburyo bw'ibanze, ubwubatsi bw'icyitegererezo, cyangwa isesengura ry’imibare ryuzuye. Ibindi bizamini bizakenerwa kugirango hamenyekane uruhare runini rwateganijwe, radiyo, hamwe nibyumba byumba bikoreshwa mubibazo byo gutezimbere no kubishyira mubikorwa.
Abanditsi bavuga ko kugereranya 1.000 ugereranije n’urwego 10 rw’urusaku basanze nta mbuga y’urusaku itandukanya intsinzi no gutsindwa. Ahubwo, bavuga ko imipaka yagaragaye kuburyo bwibanze buhagarara hakiri kare. Iri ni itandukaniro ryingirakamaro: intego z urusaku ntizishobora ubwazo kumenya niba surrogate yishura, mugihe imyitwarire yo guhagarika igisubizo ishobora kubuza inyungu zose zishoboka. Ibisobanuro ntibitanga urusaku, guhagarika ibipimo, cyangwa ingano ya buri ngaruka zavuzwe.
Uru rupapuro rutangaza kandi ibisubizo bito iyo bifatanije na surrogate imwe ku cyitegererezo cy’icyizere cyo mu karere: umubare w’ibibazo byakemuwe wagabanutse uva kuri 88 ugera kuri 86. Porogaramu ya interpolation yasohotse yagumye imbere ya 103, nk'uko bivugwa. Iri gereranya ryerekana ko kongeramo surrogate bidahita bitezimbere uburyo bukomeye kandi bishobora gutanga ikiguzi mugihe igisubizo gisanzwe kimaze gusiga umwanya muto wo kwihuta. Inkomoko ntisobanura software, amagambo yimpushya, ibidukikije byogukora, cyangwa niba igereranya ryakoresheje ingengo yimibare imwe.
Ibibazo bikurikira byo kugenzura ni uburyo kandi bufatika. Abasomyi bakeneye impapuro zuzuye, pseudocode yinyongera, code, nibisubizo bibisi kugirango bagenzure ibipimo ngenderwaho, amahugurwa yicyitegererezo, amategeko yo kwemererwa, ibiciro byo kubara, hamwe no kumva hyperparameter. Bakeneye kandi kwigana mubindi bikorwa bifatika, imiryango ikemura, ibipimo, hamwe nakazi keza ka injeniyeri. Kugeza icyo gihe, umwanzuro ushyigikiwe cyane ni itegeko: iyi progaramu yerekana ibimenyetso byerekana ko imitsi ya surrogate ishobora gufasha gutezimbere mugihe uruhare rwabo, radiyo ikora, hamwe nubufatanye nuburyo bwibanze bigenzurwa neza, ntabwo ari ibimenyetso byerekana ko ari byiza cyane muburyo budasanzwe.
