It can be simpler than policy-gradient optimization, but quality depends on the candidate pool and scorer.

A rejection-sampling fine-tuning loop prompts a policy to generate multiple candidates, scores them with a reward model or task-specific verifier, and retains examples meeting a selection rule. The model is then fine-tuned with supervised learning on selected responses. In verifiable tasks, tests or exact-answer checks can provide a reward; open-ended tasks often rely on learned preference scores. Llama 2-Chat’s paper describes rejection sampling as one stage of its alignment pipeline. RFT can transfer best-of-N behavior into a model, but cannot select answers absent from the candidate pool and may overfit or exploit an imperfect scorer. It is not equivalent to every RLHF recipe and does not guarantee higher quality or diversity.

Mustaqbalka Diidmada Muunadaynta Fine-Tuning
RFT waxay udub dhexaad u tahay tababarka ka dambeeya casriga ah, oo inta badan la isticmaalo ka hor ama ay weheliyaan hababka RL sida PPO iyo DPO. Racfaankeedu wuxuu ku koraa faaqidaad raqiis ah iyo hubiyeyaal toos ah oo xoog leh: sida moodellada ay ugu fiicnaanayaan is-abuurista iyo is-hubinta, muunad diidmo ah oo soo noqnoqotay waxay taageertaa xogta-synthetic-data iyo is-hormarinta wareegyada. Filo is dhexgal adag oo leh moodooyin caqli-gal ah oo soo saara silsilado feker oo la xaqiijin karo, iyo daraasad joogto ah oo ku saabsan sida looga fogaado jabsiga abaal-marinta iyo burburka kala duwanaanshiyaha marka lagu tababaro si isdaba joog ah wax soo saarkiisa moodeelka.
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.
- Lasoco qaababka guuldarada oo dib u leyli dardargelinta ama socodka shaqada si joogto ah.

Su'aalaha soo noqnoqda
What is Rejection Sampling Fine-Tuning?
Rejection-sampling fine-tuning generates candidate responses, filters them with a reward model or verifier, and uses selected examples for supervised training. It can be simpler than policy-gradient optimization, but quality depends on the candidate pool and scorer.
Which loop best describes how Rejection Sampling Fine-Tuning improves a model?
RFT waxay muunaday jawaabo badan, shaandheeyayaasha kuwa ugu dhibcaha sarreeya, waxayna si fiican u habeeyaan moodalka guuleystayaashaas.
Goobaha la xaqiijin karo sida xisaabta ama koodka, maxaa u adeegi kara abaal-marin ahaan?
Hawlaha la hubin karo, RFT waxay isticmaali kartaa saxnaanta saxda ah ama imtixaanada cutubka gudbinta, iyada oo ka fogaanaysa qaabka abaalmarinta la bartay.
Which model family does the cited paper describe using rejection sampling in its alignment pipeline?
The Llama 2 paper describes rejection sampling as one stage of the Llama 2-Chat alignment pipeline.
Why might a team choose rejection-sampling fine-tuning over a policy-gradient approach for some tasks?
RFT uses generated and filtered examples for supervised updates, though generation, scoring, and data quality still incur costs.
Tababarka ku saabsan muunadaha abaal-marinta ugu sarreeya si wax ku ool ah muxuu sameeyaa?
Marka aad wax ka barato jawaabaha la sifeeyay ee sare, qaabku waxa uu dhexgeliyaa hab-dhaqanka tayada sare leh ee hal jiil.
