In this video, AWS generative AI expert Emily Webber explores reinforcement learning with human feedback (RLHF) and its importance in AI development. She explains how RLHF addresses subjectivity and objectivity issues through ranked human preferences at scale. The video covers original GPT models, human labeling, reward models, and updating GPT models using reward signals. Webber demonstrates RLHF implementation using SageMaker GroundTruth and provides a hands-on workshop for practical experience.
