Machine Learning (ML)
FoundationsCore AI Concepts
Also called: ML
Machine learning is the paradigm of training systems to identify patterns from data rather than programming them with explicit, hard-coded rules. A fraud model is not told what fraud looks like; it is shown examples of fraudulent and legitimate transactions and works out the distinguishing patterns itself. Almost everything now sold as AI is machine learning underneath.
In practice
A machine learning system is only as good as the data behind it, so the first question to put to any such claim is where the training data came from and whether the company has the right to use it. The second is what happens as the world moves, because a system learned from history keeps applying history until someone retrains it.
