- “A set of condition/action rules ”(J. HOLLAND, 1992, p. 172)
Classifiers are necessary in adaptive systems . They work on inputs , detected from the environment by specific sensors . Any such input is matched with the behavioral set of rules proper of the system, according to a general “if… then” rule .
In HOLLAND's model , an output is produced and fed back to the environment . The obtained result may lead to an adjustment of the rules strength.
This is similar to the back propagation algorithm (HINTON, 1991).
Classifiers are basic, for ex. for pattern recognition .
