    • Awọn ere lati išaaju epoch

  2. Iru algoridimu wo ni o ni nkan ṣe pẹlu isọdọtun ere akojọpọ?

  5. What does within-prompt reward normalization provide to a GRPO update?
    • A relative, scaled advantage for each response compared with others for the same prompt
    • A guarantee that all prompt difficulty differences disappear
    • A higher learning rate
    • A way to make every response receive the same reward
  6. What happens when every response in a prompt group receives the same reward?
    • Every response gets a positive advantage
    • Centering gives no relative advantage; zero spread also requires numerical handling
    • The group mean doubles the reward
    • The model stops needing a policy objective
  7. Which PPO-style update element does GRPO retain?
    • A separately learned value network
    • K-means clustering over tokens
    • A clipped policy objective
    • A language-model tokenizer
  8. What can a KL penalty relative to a reference policy help constrain in GRPO?
    • The number of prompts in each group
    • The length of the tokenizer vocabulary
    • The resolution of generated images
    • How far the updated policy drifts from the reference policy
