Via Wikipedia: "Set in August and September 2002, the story follows Cayce Pollard, a 32-year-old marketing consultant who has a psychological sensitivity to corporate symbols. The action takes place in London, Tokyo, and Moscow as Cayce judges the effectiveness of a proposed corporate symbol and is hired to seek the creators of film clips anonymously posted to the internet.
The novel's central theme involves the examination of the human desire to detect patterns or meaning and the risks of finding patterns in meaningless data. Other themes include methods of interpretation of history, cultural familiarity with brand names, and tensions between art and commercialization. The September 11, 2001 attacks are used as a motif representing the transition to the new century. Critics identify influences in Pattern Recognition from Thomas Pynchon's post-structuralist detective story The Crying of Lot 49."
Via Wikipedia: "Pattern recognition algorithms generally aim to provide a reasonable answer for all possible inputs and to do fuzzy matching of inputs. 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.
Pattern recognition is studied in many fields, including psychology, psychiatry, ethology, cognitive science and computer science."
