What is machine learning and how it works

Machine learning (ML) is the use of mathematical data models that help a computer learn without direct instructions. It is considered a form of artificial intelligence (AI). Machine learning uses algorithms to identify patterns in data. Based on these patterns, a data model is created for prediction. The more data such a model processes and the longer it is used, the more accurate the results become. This is very similar to how humans hone skills in practice.

Because of the adaptive nature of machine learning, it is great for scenarios where the data is constantly changing, the properties of queries or problems are unstable, or it is virtually impossible to write code to solve.
