chatgpt optimizing language models for dialogue的进一步展开说明

Methods

In this section, the authors describe the methods used to train the model, including reinforcement learning from human feedback and data collection setup. They also explain the process of creating a reward model for reinforcement learning.

Reinforcement Learning from Human Feedback

The model was trained using Reinforcement Learning from Human Feedback (RLHF), employing similar methods as InstructGPT but with slight differences in data collection setup. Initially, an initial model was trained using supervised fine-tuning, where human AI trainers provided conversations in which they played both the user and an AI assistant. These trainers had access to model-written suggestions to help them compose their responses. The dialogue dataset obtained from this step was then mixed with the InstructGPT dataset, which was transformed into a dialogue format.

Creating a Reward Model

To create a reward model for reinforcement learning, comparison data was collected. This involved taking conversations that AI trainers had with the chatbot and selecting a model-written message at random. Several alternative completions were sampled and AI trainers were asked to rank them based on quality. This information was used to create reward models for fine-tuning the model using Proximal Policy Optimization. The authors performed several iterations of this process.

Data Collection Setup

The authors explain that the data collection setup for RLHF had slight differences compared to InstructGPT. They mention that an initial model was trained using supervised fine-tuning, where AI trainers played both sides of a conversation and had access to model-written suggestions. The dialogue dataset obtained from this step was combined with the InstructGPT dataset, which was transformed into a dialogue format.

Creation of Reward Models

The authors describe the process of creating a reward model for reinforcement learning. They explain that conversations between AI trainers and the chatbot were used to collect comparison data. A model-written message was chosen randomly, and alternative completions were generated and ranked by AI trainers. The resulting reward models were then used to fine-tune the model using Proximal Policy Optimization. Several iterations of this process were performed to improve the model’s performance.
