VerifiedRLHF trains a reward model by collecting human preference ratings, then fine-tunes the language model using reinforcement learning algorithms such as PPO; however, the reward model can be deceived by adversarial inputs and cannot enumerate all variants of harmful request expressions.79% similarVerified确认偏误与RLHF（基于人类反馈的强化学习）训练方式相关，模型被优化为生成让人满意的回答78% similarUnverifiedIn RLHF, if preference data is of low quality or contains systematic bias, the reward model will learn incorrect signals, causing the model's behavior to deviate from expectations.77% similarUnverifiedFine-tuning embedding models with contrastive learning requires labeled data (positive samples of successful hires and negative samples of rejected candidates) to achieve significant performance gains.77% similarUnverifiedRLCD is a policy-gradient-based reinforcement learning method (an unofficial name coined by the author) that optimizes decision models for strictly proper scoring rules, granting maximum reward only when the model outputs mathematically calibrated probabilities.76% similar
