Machine Learning
Machine learning is a branch of artificial intelligence that enables computers to learn from data without being explicitly programmed. Using algorithms that identify patterns in data, ML systems can make predictions, recognize images, translate languages, and automate decision-making.
Key approaches include neural networks, support vector machines, and ensemble methods. Recent advances in deep learning have enabled breakthroughs in computer vision, natural language processing, and scientific discovery.
