Machine learning gives computers the ability to learn without being explicitly programmed (Arthur Samuel, 1959).[1][2] It is a subfield of computer science.

The idea came from work in artificial intelligence.[3] Machine learning explores the study and construction of algorithms which can learn and make predictions on data.[4] Such algorithms follow programmed instructions, but can also make predictions or decisions based on data.[5]: 2  They build a model from sample inputs.

Machine learning is done where designing and programming explicit algorithms cannot be done. Examples include spam filtering, detection of network intruders or malicious insiders working towards a data breach,[6] optical character recognition (OCR),[7] search engines and computer vision.

Using machine learning has risks. Some algorithms create a final model which is a black box.[8] Models have been criticized for biases in hiring,[9] criminal justice,[10] and recognizing faces.[11]
