It can improve results when the model sometimes produces a good candidate and the scorer identifies it reliably. More samples cost more generation and can amplify errors in an imperfect scorer.

Best-of-N samples N candidate responses from a model and returns the one with the highest score under a reward model, verifier, or heuristic. Self-consistency is a special case that aggregates final answers by majority vote. If each independent sample has probability p of success and a perfect verifier can recognize success, the chance at least one candidate is correct is 1−(1−p)^N. Real outputs are not necessarily independent and real scorers are imperfect. Research on reward-model overoptimization finds that optimizing against a proxy can eventually reduce gold-standard performance, including in best-of-N selection.

Mustaqbalka Sambaynta iyo Dib-u-dejinta ugu Wanaagsan
Inference-time scaling research studies adaptive sample counts, verifiers, and reward-model calibration. The right N depends on the task, sample quality, scorer reliability, and compute budget. Evaluations should report both the selected-answer metric and the added generation/scoring cost.
Ku dhaqangelinta
Maxay muhiim u tahay
- Xawaaraha iyo miisaanka. Socodka shaqada luqaddu si dhakhso leh ayay u socon kartaa iyada oo aan la hurayn joogteynta.
- Helitaanka iyo gaarsiinta. Waxay balaadhisaa gelitaanka luqadaha iyo qaababka isgaarsiinta.
- Go'aamo cad. Kooxuhu waxay waqti badan ku qaadan karaan xukunka halka otomaatiggu uu qabanayo ku celcelinta.
Iska ilaali
- Xaqiiqooyinka dhalanteed waxay si deggan u geli karaan warbixinnada, taageerada socodka, ama natiijooyinka cilmi-baarista.
- Dareenka degdega ahi wuxuu abuuri karaa natiijooyin aan iswaafaqayn codsiyada la midka ah.
- Xogta qoraalka xasaasiga ah ayaa laga yaabaa in la kashifo haddii kontaroolada gelitaanka ay daciif yihiin.
Tallaabooyinka xiga
- Qeex qaabka wax soo saarka, codka, iyo heerarka tayada ka hor inta aan la baahin.
- Jawaabaha salka ku haya ilo lagu kalsoon yahay mar kasta oo saxnidu ay muhiim tahay.
- Hayso isbaarada dib u eegista bini aadamka ee wax soo saarka sare.

Su'aalaha soo noqnoqda
What is Best-of-N Sampling and Reranking?
Best-of-N is an inference-time selection method: sample multiple outputs and use a scorer or verifier to choose one. It can improve results when the model sometimes produces a good candidate and the scorer identifies it reliably. More samples cost more generation and can amplify errors in an imperfect scorer.
Waa maxay fikradda udub-dhexaadka ah ee ugu-wanaagsan ee muunada?
Best-of-N waxay soo jiidataa jawaabaha musharixiinta badan ka dibna dib u darajo ku bedesho, soo celisa midka ugu buundada badan.
When is best-of-N most likely to help?
More candidates help only if a good answer sometimes appears and the scorer can recognize it; neither condition is guaranteed.
Maxaa inta badan go'aamiya in-u-fican-N ay dhab ahaantii hagaajinayso natiijooyinka?
Xulashadu waxay u fiican tahay oo kaliya sida dib-u-dejinta; gooldhaliye daciif ah ama eex ayaa dooran kara jawaabo khaldan.
What can happen when N becomes large and the reward model is an imperfect proxy?
Research measures reward-model overoptimization in best-of-N: selecting extreme proxy scores can eventually lower gold-reward performance.
Istaraatiijiyadee fudud ee dib-u-dejinta ayaa sidoo kale loo yaqaannaa is-waafajinta?
Is-waafajintu waxay muunadaysaa silsilado badan oo sababaynta waxayna doorataa jawaabta kama dambaysta ah ee silsiladaha badankoodu ku heshiiyaan.
