Machine learning (ML) is a subset of artificial intelligence (AI) that enables computers to learn from data and make predictions or decisions without being explicitly programmed. In healthcare, ML has the potential to revolutionize patient care by enhancing diagnostics, treatment planning, and administrative processes.

Machine learning can be broadly categorized into two types: supervised learning and unsupervised learning.
Supervised Learning: Learning from labeled data to make predictions. Example: Diagnosing diseases from medical images.
Unsupervised Learning: Learning from unlabeled data to find patterns. Example: Identifying patient clusters with similar symptoms.
Unsupervised Learning: Learning by interacting with the environment. Example: Optimizing treatment plans for better outcomes.
