Also known as: ML
A field of AI where algorithms learn patterns from data to make predictions or decisions without explicit rule-based programming.
DESCRIPTION
Machine Learning (ML) develops algorithms that learn from data to perform tasks such as prediction, classification, clustering, and control. Core paradigms include supervised, unsupervised, and reinforcement learning. Modern ML spans linear models to deep neural networks and probabilistic methods. Success depends on data quality, appropriate features, and rigorous evaluation. ML is operationalized via MLOps practices for deployment, monitoring, and governance. Ethical and regulatory concerns increasingly shape ML development and use.
ALTERNATIVE DEFINITIONS
IBM
Machine learning is a branch of artificial intelligence (AI) that focuses on the use of data and algorithms to imitate the way that humans learn, gradually improving its accuracy.
Emphasizes learning from data and iterative accuracy improvement.
Google Cloud
Machine learning is a branch of artificial intelligence (AI) that allows software applications to become more accurate at predicting outcomes without being explicitly programmed.
Highlights predictive accuracy and absence of explicit programming.
Encyclopaedia Britannica
Machine learning, in computer science, the discipline concerned with the development of algorithms that allow computers to learn from and make predictions or decisions based on data.
Stresses prediction or decision-making from data as the objective.
