We’ve fine-tuned the 774M parameter GPT‑2 language model using human feedback for various tasks, successfully matching the preferences of the external human labelers, though those preferences did not always
SFT是 Fine-Tuning的一种实现方式: 强调使用有监督数据对模型进行任务特定微调,目标是让模型的输出行为更符合人类期望。 LORA 是对 Fine-Tuning的高效优化: 通过限制参数更新范围,优化微调效率,同时保留性能。 RLHF 1.什么是 RLHF? RLHF(Reinforcement Learning with Human Feedback)是一种结合强化学习与人类反馈的...

Examples: Train GPT2 to generate positive movie reviews with a BERT sentiment classifier, full RLHF using adapters only, train GPT-j to be less toxic,Stack-Llama example, etc. How PPO works Fine-tuning a language model via PPO consists of roughly three steps: ...
Fine-tuning GPT-3 on a healthcare-specific dataset would enable it to comprehend better and generate medical text, making it a valuable tool for healthcare professionals. Fine-tuning methods Fine-tune LLMs Large Language Model (LLM) fine-tuning is a supervised learning process that leverages lab...
Fine-tuning large pretrained models is often prohibitively costly due to their scale. Parameter-Efficient Fine-Tuning (PEFT) methods enable efficient adaptation of large pretrained models to various downstream applications by only fine-tuning a small number of (extra) model parameters instead of all ...
