Abstract
Tuning parameters of artificial neural networks (ANN) is a very complex task that typically demands a lot of experimental work performed by developers. In order to avoid this hard work, the automatic tuning of these parameters is proposed. A real-coded genetic algorithm (GA) was developed for this purpose. This, so-called meta-GA, algorithm acts as a meta-heuristic that searches for the optimal values of ANN parameters using the genetic operators of crossover and mutation and evaluates quality of solutions, obtained after applying the ANN for fire analysis of steel frames. As matter of fact, steel exhibits very unusual wavy behavior which is a very difficult to model by a close form empirical models when heated to the temperatures between 250°C and 600°C. Therefore, the use of ANN was one of the possible solutions which proved to be very promising. However, the results of this ANN with manual parameter setting by an expert can significantly be improved when using the meta-GA for automatic searching the optimal parameter setting of the original ANN algorithm.
