Data mining.<\/p>\n<p>Data mining is the process of extracting patterns from large data sets using statistical, mathematical, and machine learning techniques. It is a subset of data science and big data.<\/p>\n<p>Data mining is used to discover new patterns and relationships in data that would not be apparent by simply looking at the data. It can be used to identify trends, predict future events, and make better decisions.<\/p>\n<p>Data mining is a powerful tool that can be used to solve a variety of problems. However, it is important to note that data mining is not a silver bullet. It is important to have a clear understanding of the problem that you are trying to solve before you start data mining.<\/p>\n<p>Here is a brief explanation of each option:<\/p>\n<ul>\n<li><strong>Big data<\/strong> is a term used to describe the large and complex data sets that are generated by modern technology.
