In conventional programming, humans use their intelligence and knowledge to create rules expressed in software code. In contrast, machine learning relies on data and success criteria, using this data to generate rules while optimizing that criteria.

Machine learning methods are not new: they are older than computers. We didn't refer to them as machine learning in the past, but as statistical methods. This includes techniques such as linear regression, logistic regression, and linear discriminant analysis (LDA). Some of these methods, like linear regression, date back to the early 19th century.
