Untitled. Thanks for your interest in Copycat!
Copycat is written in Common Lisp. The system is unfortunately rather outdated: it will not run as is without some updates for modern versions of Common Lisp, and some platform-specific modifications to the graphics files. Melanie Mitchell. Complexity Explorer. Pattern Recognition on the Web. Pattern recognition. Pattern recognition algorithms generally aim to provide a reasonable answer for all possible inputs and to perform "most likely" matching of the inputs, taking into account their statistical variation.
This is opposed to pattern matching algorithms, which look for exact matches in the input with pre-existing patterns. A common example of a pattern-matching algorithm is regular expression matching, which looks for patterns of a given sort in textual data and is included in the search capabilities of many text editors and word processors. In contrast to pattern recognition, pattern matching is generally not considered a type of machine learning, although pattern-matching algorithms (especially with fairly general, carefully tailored patterns) can sometimes succeed in providing similar-quality output to the sort provided by pattern-recognition algorithms.
