| Popis: | In systems identification, the studied phenomena are accompanied by uncertainties, whether arising from measurement data or computational calculations. Interval data provides a valuable way to represent available information on complex problems where uncertainty, inaccuracy, or variability must be taken into account. The present work aims to determine interval parameters for a model considering data measurement uncertainties using the MQ estimator and neural networks. The main objective of this work is to apply this technique in audiometric systems, particularly in the automatic detection of auditory responses taking into consideration the flexible computing concepts that offer solutions tolerant to subjectivity, inaccuracy or uncertainty. It was possible to obtain a model with interval parameters that allow an infinite set of parameters to be evaluated as a limited range. The model was validated using two methods, one with prediction of 2 steps ahead, using the MQ estimator and extended to another representation as neural networks 5 steps delay. It has been shown that interval parameters generate interval results that contain most validation data improving system reliability.
