Machine Learning (ML)
Definition
A type of AI in which software learns patterns from data instead of being explicitly programmed with rules, then uses those patterns to make predictions on new data.
Machine learning (ML) is the most common technique behind modern artificial intelligence. Instead of a developer writing rules for every case, the system is shown many examples and learns the patterns that connect inputs to outcomes.
The three classic types are supervised learning (learning from labelled examples), unsupervised learning (finding structure in unlabelled data), and reinforcement learning (learning by trial and error). Read more in our guide to machine learning.
