Machine learning types include supervised learning, unsupervised learning, and reinforcement learning.

• Supervised learning involves training a model on labeled data to make predictions.
• Unsupervised learning involves finding patterns in unlabeled data.
• Reinforcement learning involves learning through trial and error based on rewards and punishments.
