Mhinduro uye tsananguro zvinoonekwa paunenge uchitora bvunzo.

  1. Ndeipi yekutanga kubuda kwemubairo modhi kune yakapihwa kukurumidza-mhinduro vaviri?
    • A single scalar score
    • Mhinduro yemavara akazara
    • Mukana wekugovera pamusoro pemazwi
    • Rondedzero yematokeni anodiwa
  2. What feedback format did the InstructGPT paper collect to train its reward model?
    • A guaranteed correctness label for every possible answer
    • Human rankings of several model responses, converted into pairwise preferences
    • A single sentiment score for each training prompt
    • Only binary safety labels with no response comparisons
  3. Ko chiyero chemubairo-modhi yekurasikirwa chinogonesa chii?
    • Mhedziso yemubairo kukosha kwemhinduro yega yega
    • Iyo inotevera-chiratidzo kufanotaura chokwadi
    • Kuti mhinduro yakasarudzwa inokwira kupfuura yarambwa
    • Hurefu hwemhinduro
  4. Chii chinonzi 'kupa mubayiro'?
    • Kubira mukwikwidzi wemubayiro modhi
    • Nzira yekukurumidza kudzidzira
    • Kunyora mubairo chiratidzo
    • Iyo mutemo inoshandisa kukanganisa mumuenzaniso wemubairo kuti uwane zvibodzwa zvepamusoro pasina mhando chaiyo
  5. Ko muenzaniso wemubairo unotorwa sei kubva mumuenzaniso wemutauro?
    • Nekutsiva iyo token-prediction head ine imwechete scalar inobuda musoro
    • Nekuwedzera mamwe matipi ekutarisisa
    • Nekubvisa ese ma transformer layers
    • Nokupeta mashoko
  6. Muenzaniso wemubairo unoshandiswa sei panguva yekufungidzira mune yakanakisa-ye-N sampling?
    • Kudzidzira N mibayiro modhi mune zvakafanana
    • Kugadzira mhinduro dzakawanda uye kushandisa iyo mubairo modhi kusarudza yepamusoro-yepamusoro-zvibodzwa
    • Kusarudza maN akajairika tokeni
    • Avhareji N modhi yekutarisa nzvimbo
  7. Why might an RLHF study use an ensemble of reward models during training?
    • To guarantee that reward hacking is impossible
    • To replace the human preference data with exact correctness labels
    • To estimate disagreement or uncertainty across learned preference scorers
    • To ensure every candidate receives the same score
  8. Why should reward-model evaluations include held-out comparisons?
    • To ensure training comparisons are never used
    • To make every output identical
    • To guarantee the reward is unbiased
    • To test whether preferences generalize beyond the training comparisons
