<!-- Provide a quick summary of what the model is/does. --> |
|
|
**PPO-C** (PPO with Calibrated Reward Calculation) is an RLHF algorithm to mitigate verbalized overconfidence in RLHF-trained Large Language Models. |
|
|
PPO-C adjusts standard reward model scores during PPO training. It maintains a running average of past reward scores as a dynamic threshold to |
|
|
classify responses, and adjusts the reward scores based on model expressed verbalized confidence. |
|
|
Please refer to our preprint ([Taming Overconfidence in LLMs: Reward Calibration in RLHF](https://arxiv.org/abs/2410.09724)) and [repo](https://github.com/SeanLeng1/Reward-Calibration) for more details. |
