  12. What is Data Mining? • The process of identifying hidden patterns, trends, and relationships in large quantities of data. Why Do Data Mining? • To discover useful information for making decisions. • Too many variables for Classical Statistical methods to work. • Large Number of Records 108 - 1012 • Gigabyte – Terabyte • High Dimensional Data • Lots of Variables (10 – 104 attributes)

  13. The Huber-Wegman Taxonomy of Data Set Sizes
