What are RLHF Tools in the UK?
Reinforcement Learning from Human Feedback (RLHF) tools are used to fine-tune AI models by incorporating human preferences into the training process. These tools leverage reinforcement learning algorithms, such as Proximal Policy Optimization (PPO), to adjust model outputs based on human-labeled rewards. By training models to align with human values, RLHF improves response quality, reduces harmful biases, and enhances user experience. Common applications include chatbot alignment, content moderation, and ethical AI development. RLHF tools typically involve data collection interfaces, reward models, and reinforcement learning frameworks to iteratively refine AI behavior.
