Data Science and Machine Learning (Theory and Projects) A to Z - Process of Learning from Data: Unsupervised Learning an

The video tutorial covers three main types of machine learning: supervised, unsupervised, and reinforcement learning. Supervised learning involves using labeled data to train models, while unsupervised learning focuses on grouping similar data without labels, often through clustering. Reinforcement learning is highlighted as a method where an agent learns by interacting with an environment, receiving rewards, and adjusting actions to achieve a goal. The video concludes with a brief mention of features and their importance in machine learning, setting the stage for the next video.
