In Al, machine learning (ML) is a method for systems to learn from data. In circumstances where there is a lack of data, machine learning approaches are useful. They are significant because practically all human decisions are made in such situations. 

The current pandemic crisis encourages investments in AI and ML to adapt to a changing business environment. Many verticals, such as finance, retail, manufacturing, and transportation, are undergoing fundamental restructuring as a result of harsh economic conditions.

In this report, over 25,000 patent applications filed worldwide between 2011 and 2021 in the field of machine learning were examined.
