Due to advances in the data mining (DM) field, it is possible to extract knowl- edge from raw data. Indeed, powerful techniques such as neural networks (NNs) and more recently support vector machines (SVMs) are emerging. While being more flexible models (i.e. no a priori restriction is imposed), the per- formance depends on a correct setting of hyperparameters (e.g. number of hidden nodes of the NN architecture or SVM kernel parameter). On the other hand, the multiple regression (MR) is easier to interpret than NN/SVM, with most of the NN/SVM applications considering their models as black boxes. Another relevant aspect is variable selection, which leads to simpler models while often improving the predictive performance. In this study, we present an integrated and computationally efficient approach to deal with these issues. Sensitivity analysis is used to extract knowledge from the NN/SVM models,
