Abstract

Neural Networks (NNs) have been widely used in many industrial processes for prediction and optimization and they have been proven to be useful tools for explaining complex processes. The main objective of this work consists of improving the accuracy of a Radial Basis Function Neural Network Redesigned by Genetic Algorithm and Mahalanobis distance for predicting a welding process. The evaluation function in this approach considers the use of the Coefficient of Determination R2. The results indicated that the statistical method R2 is a good alternative to validate the efficiency of the Neural Network model. The principal conclusion in this work is that the Radial Basis Function Redesigned by Genetic Algorithm and Mahalanobis distance had a very good performance in a real case, considering the prediction of specific responses in a welding process.
