past when the sample data was collected, the future predictions can

also be expected to be right.

Application of machine learning methods to large databases is called

data mining. The analogy is that a large volume of earth and raw material

is extracted from a mine, which when processed leads to a small

amount of very precious material similarly in data mining, a large volume

of data is processed to construct a simple model with valuable use,
