Numerosity reduction – sampling design pattern
This design pattern explores the implementation of sampling techniques for data reduction.
Sampling belongs to the numerosity reduction category of data reduction. It can be used as a data reduction technique, as it represents a very large amount of data by a much smaller subset.
Sampling is essentially a method of data reduction to determine the approximate subset of a population that has the characteristics of the entire population. Sampling is a general approach to choose a subset of data to accurately represent a population. Sampling is performed by various methods that differ in the way in which they define what goes into the subset and the way candidates are located for that ...
