ABSTRACT:
There is provided an inference knowledge extracting apparatus capable of being adapted to a change of input/output data. In a fuzzy rule individual group storing section is stored a group of individuals having a gene string associated with a fuzzy rule of a fuzzy rule storing section by a fuzzy rule gene associating section. A fuzzy rule individual selecting section stochastically selects individuals having a small output error with respect to the input/output data based on a calculation result of fitness obtained by an individual fitness calculating section. A fuzzy rule individual gene manipulating section executes a gene manipulating operation on each individual selected by the individual fitness calculating section. The fuzzy rule gene associating section, individual fitness calculating section, fuzzy rule individual selecting section, fuzzy rule individual gene manipulating section and a rule weight deciding section are functioned, thereby executing an evolutionary adaptation operation to extract a fuzzy rule that is evolutionarily adapted to the change of the input/output data.
