Kwenzekeni
Abacwaningi baqhathanise okuhlukile okuyisishiyagalolunye kusukela kumindeni eyimodeli eyisihlanu enezilinganiso ezimbili ezikhethekile zokubikezela amanani kagesi e-Germany, e-Poland nase-Spain, besebenzisa idatha kusukela ngo-2021 kuya ku-2025. Iphepha libika ukuthi amamodeli we-TabPFN kuphela asebenze ngokungaguquki nangokuphawulekayo ngaphezu kwamabhentshimakhi kuzo zonke izimakethe ezintathu nazo zonke izinyathelo zezibalo. Leyo nzuzo yokusebenza ayizange idlule ngendlela efanayo ku-arbitrage yesitoreji sebhethri: I-TabPFN yenze kahle kakhulu ngamabhidi angenamkhawulo namasu we-riskier quantile, kuyilapho ibhentshimakhi ye-Distributional Deep ibe nenzuzo enkulu ngaphansi kokubekezelela ubungozi obuphansi.
I-arXiv preprint, ethunyelwe ngomhla ka-31 Agasti 2026, ihlola amamodeli ayisisekelo emsebenzini wemakethe yamandla ophathekayo kunokuba iwaphathe njengezibikezelo ezijwayelekile. Iqhathanisa okuhlukile okuyisishiyagalolunye okuvela emindenini emihlanu yamamodeli esisekelo kumodi ye-zero-shot ngokuqhathaniswa nezilinganiso ezimbili zesimanjemanje zokubikezela amanani kagesi.
Ukuhlola kuhlanganisa i-Germany, Poland kanye ne-Spain ngonyaka ka-2021–2025 futhi kukala kokubili iphuzu nokunemba kwesibikezelo sezulu okungenzeka. Iphinde ihlole umphumela wezomnotho osebenzayo walezo zibikezelo ngokusebenzisa i-arbitrage yesitoreji samandla ebhethri.
Ngokusho kwephepha, i-TabPFN iwukuphela komndeni oyimodeli yesisekelo odlula njalo futhi ngokuphawulekayo amabhentshimakhi kuzo zonke izimakethe ezintathu nezibalo. Umthombo awunikezi amagama emodeli ngayinye, amaphuzu ezinombolo, noma izilungiselelo zokuhlola ezinemininingwane ku-abstract.
Imiphumela yezomnotho ebikiwe inemibandela ekusethweni kohwebo. I-TabPFN isebenza kahle kakhulu ngaphansi kwamabhidi angenamkhawulo kanye namasu asekelwe ku-riskier quantile, kuyilapho ibhentshimakhi ye-Distributional Deep ikhiqiza inzuzo ephezulu uma ukubekezelela ubungozi kuphansi. Ngakho-ke leli phepha lihlukanisa ukubusa kokubikezela nokubusa kwe-arbitrage.

Kungani kubalulekile
Ucwaningo luphonsela inselelo umbono wokuthi imodeli eqinile yokubikezela injongo evamile ingashintsha ngokuzenzakalelayo amamodeli aklanyelwe imakethe ethile kagesi. Imiphumela yakhona iphakamisa ukuthi ukunemba kwesibikezelo sezibalo kanye nenani lezezimali kungahluka, ikakhulukazi lapho opharetha bebhethri bebhekene nemikhawulo yengozi ehlukile. Ezinhlanganweni ezenza izinqumo zokuhweba amandla noma isitoreji, ukukhetha imodeli kungase kudingeke ukuthi kubhekelele isu lesinqumo, imakethe, nokubekezelela ubungozi kunokuthembela kumphumela owodwa webhodi labaphambili.
Isibikezelo senani likagesi siwukuhlola okuwusizo kokuthi amamodeli ayisisekelo adluliswa yini ezizindeni ezikhethekile nezingezona izilimi. Umphumela wephepha ukhombisa ukuthi ukudluliswa kwemali kungabaluleka ngaphandle kokwenza amamodeli akhethekile aphelelwe yisikhathi.
Kubasebenzisi bebhethri, inhloso efanele ayikona nje ukunciphisa iphutha lesibikezelo. Imodeli enamandla ngokwezibalo ingase ikhiqize izinqumo zokuhweba ezingakhangi kangako uma isu libeka isisindo esikhulu engcupheni engase ibe khona noma ikhawulela ukuvezwa kokubhida.
Okutholakele kuhambisana nezimangalo zokuthi amamodeli ayisisekelo angangena esikhundleni sezinhlelo eziqondene nesizinda. Kulokhu kuhlola, ukumiselela akukona okomhlaba wonke: imodeli ekhethwayo ishintsha ngesinqumo sezomnotho kanye nokubekezelela ubungozi komsebenzisi.
Ngenxa yokuthi umthombo ungowokuphrinta ngaphambili kwe-arXiv, okutholiwe kufanele kuthathwe njengemiphumela yokuhlolwa ebikiwe yababhali esikhundleni sobufakazi obuqinisekisiwe obuzimele bokuphakama kwezentengiso.

Ongakubuka ngokulandelayo
Ukucutshungulwa okwengeziwe kufanele kuveze ukuthi okutholakele kungaphezu kwezimakethe ezintathu, isikhathi sokuhlola sika-2021–2025, kanye namamodeli athile kanye nezilinganiso ezihloliwe. Umthombo awusunguli ukusetshenziswa kokukhiqiza, izindleko zokusebenza, izimfuneko zokufinyelela idatha, noma ukusebenza ngaphansi kwezimo zemakethe ebukhoma. Futhi ayibonisi ukuthi imiphumela ebikiwe ijwayeleka kwezinye izimpahla zesitoreji, imithetho yokubhida, imikhathizwe yokubikezela, noma amasistimu okulawula ubungozi.
Ukuphindaphinda okuzimele kuzo zonke izimakethe zikagesi ezengeziwe, izinkathi zesikhathi, imikhathizwe yokubikezela kanye nemithetho yokubhida kuzohlola ukuthi umphumela uphatheka kangakanani.
I-abstract yaleli phepha ayiziqophi izimo zokufinyelela, ukugunyazwa, izindleko zokucatshangelwa, izimfuneko zedatha yokuqeqeshwa, noma noma iyiphi imodeli ehloliwe iyatholakala ukuze isetshenziswe. Abamukeli abasebenzayo bazodinga leyo mininingwane ngaphambi kokuhlola ukuthunyelwa.
Umthombo awusunguli inzuzo yemakethe ebukhoma, ukukhuthazela ekushintsheni imithetho yemakethe, noma ukusebenza ngemva kwezindleko zokwenziwayo nezinye izithiyo zokusebenza. Leyo mibuzo ihlala ivulekile.
Ukuhlola okuzayo kufanele kuqhathanise ikhwalithi yesibikezelo kanye nevelu ye-arbitrage ngaphansi kwemikhawulo yengcuphe ecaciswe ngokucacile, njengoba izinguquko zezinga ezibikiwe phakathi kwamasu angenamkhawulo noma ayingozi kanye namasu anengcuphe ephansi.
