AI glossary

Reinforcement learning from human feedback (RLHF) is a method for machine learning (ML) used in the development of large language models (LLMs). It uses human feedback to create a "reward model" that then automatically optimizes the system's responses. It was used in the development of ChatGPT to refine the model's responses before it was released.

A robot is a machine that can perform actions automatically (sometimes autonomously). Robots usually contain computer systems programmed to perform their tasks. Research and development of robots are known as robotics. Robots are often used in an industrial context, such as in factories, to perform repetitive tasks (thus automating tasks that were previously done by humans).
