Outline of machine learning
The following outline is provided as an overview of, and topical guide to, machine learning:
Machine learning is a subfield of artificial intelligence within computer science that evolved from the study of pattern recognition and computational learning theory. In 1959, Arthur Samuel defined machine learning as a "field of study that gives computers the ability to learn without being explicitly programmed". ML involves the study and construction of algorithms that can learn from and make predictions on data. These algorithms operate by building a model from a Training, validation, and test [data sets|training set] of example observations to make data-driven predictions or decisions expressed as outputs, rather than following strictly static program instructions.
How can machine learning be categorized?
- An academic discipline
- A branch of science
- * An applied science
- ** A subfield of computer science
- *** A branch of artificial intelligence
- *** A subfield of soft computing
- *** Application of statistics
Paradigms of machine learning
- Supervised learning, where the model is trained on labeled data
- Unsupervised learning, where the model tries to identify patterns in unlabeled data
- Reinforcement learning, where the model learns to make decisions by receiving rewards or penalties.
