v6 v7 20 20 As a preparation for symbolic regression a number of parameters have to be configured. A very important parameter is the grammar that restricts the possible shapes of evolved models and defines the basic building blocks for symbolic regression models (function set). 21 21 22 [[Image(grammar.png, width= 600)]]22 [[Image(grammar.png, width=300)]] 23 23 24 24 Other important parameters are the error function that should be minimized (e.g. mean of squared errors, mean of absolute errors, Pearson's R², ...), and the maximal size of the models. Additionally the parameters of the underlying evolutionary algorithm like population size, mutation rate, and number of iterations can be configured. … … 41 41 42 42 [[Image(simplification.png, width=600)]] 43 44 The final model achieved after simplification. 45 46 [[Image(simplifiedmodel.png, width=600)]] 47
