What Is Machine Learning?
Machine Learning (ML) is a subfield of Artificial Intelligence (AI) that enables systems to learn and improve from experience without being explicitly programmed. It mimics how humans learn by identifying patterns and making decisions based on data.
Core Types of Machine Learning
- Supervised Learning: Uses labeled data for prediction (e.g., classification, regression).
- Unsupervised Learning: Finds hidden patterns in unlabeled data (e.g., clustering, dimensionality reduction).
- Reinforcement Learning: Learns optimal strategies through trial and error interactions with environments.
- Semi-Supervised Learning: Combines labeled and unlabeled data to improve learning accuracy.
- Self-Supervised Learning: Generates labels from raw data to train models without manual annotation.
