Definition and Basics
Machine learning (ML) is a subset of artificial intelligence (AI) that focuses on creating systems able to automatically learn and improve from experience by identifying complex patterns in large data sets. Unlike traditional programming where rules are explicitly coded, ML models learn from examples.
Pro Tip: ML algorithms are heavily used in real-world applications such as spam filtering, recommendation systems, and image recognition.
Types of Machine Learning
- Supervised Learning: Models learn from labeled data to predict outcomes — for example, classifying emails as spam or not spam.
- Unsupervised Learning: Models identify hidden patterns in unlabeled data — e.g., customer segmentation.
- Reinforcement Learning: Models learn by interacting with an environment and receiving feedback/rewards — used in robotics and game playing.
Warning: Confusing machine learning with just coding algorithms misses the importance of training on data.
