Unsupervised learning discovers patterns and structure in data without labeled examples. Like children grouping similar toy shapes, it finds its own rules rather than learning from supplied answers. section 1.5
Learning language without direct supervision
GPT uses unsupervised learning to read a massive collection of documents, learn patterns such as grammar, and predict the most likely next word. Later supervised and reinforcement learning stages improve its conversational behavior. section 1.5
