FUZZY COGNITIVE MAP VS REGRESSION
Abstract. Fuzzy cognitive map (FCM) is considered as an alternative to regression analysis, i.e., apparatus
for modeling the inputs-output dependence based on expert-experimental information. To calculate the output value
at given input values, increments of variables are used. The optimal values of the weights of the arcs are found using
the genetic algorithm in which the chromosomes are generated from the intervals of their feasible values
and the selection criterion is the sum of the squared deviations between the model and observed output values.
Keywords: fuzzy cognitive map, regression, approximation, unknown parameters, tuning, genetic algorithm.
