Machine learning (ML) is the application of artificial intelligence (AI) to statistics and statistical analysis. ML techniques automate the search for patterns in data. Sometimes, the objective is to figure out a rule for classifying individuals based on their characteristics: For example, does a particular X-ray mean the X-rayed person is sick or well?
