Machine learning is a branch of artificial intelligence (AI) where computers learn patterns from data and make predictions or decisions without being explicitly programmed. Instead of following fixed rules, a machine learning system improves its performance by analyzing examples and experience. Key points: Data-driven: Learns from past data. Prediction: Can forecast outcomes (like sales or weather). Automation: Reduces need for manual programming. Types: Supervised Learning: Learns from labeled data. Unsupervised Learning: Finds patterns in unlabeled data. Reinforcement Learning: Learns by trial and error using feedback. In short, machine learning lets computers “learn” and make smarter decisions over time.
