☆ Machine Learning

Machine Learning (ML) is a branch of artificial intelligence that enables computers to learn from data and improve their performance on tasks without being explicitly programmed. Instead of following fixed rules, ML systems identify patterns in data and use these patterns to make predictions, classify information, or make decisions
