Machine learning (ML) is a subset of artificial intelligence (AI) that enables systems to learn and improve from experience without being explicitly programmed. It involves algorithms that analyze data, identify patterns, and make decisions or predictions.

In healthcare, ML is used for disease prediction based on patient data, while in finance, it aids in fraud detection by analyzing transaction patterns. In e-commerce, ML algorithms recommend products based on user behavior, enhancing the shopping experience. Autonomous vehicles use ML for image recognition, enabling them to interpret their surroundings. Overall, ML applications span diverse fields, revolutionizing how businesses operate and improving efficiency.
