Statistics
  • A term used in machine learning to describe the allocation of a class or a value following study of a set of data.


Computer

For example, visual pattern recognition involves the identification of two-dimensional patterns in a grey-level array. The specification of one of more patterns is done either analytically, or, more usually, by the provision of templates, which are model patterns for comparison. Pattern recognition employs the techniques of digital signal processing, image processing, and artificial intelligence.


Biology
