The goal of our work is to develop a software tool for automatic analysis of sleep stages based on artificial neural networks (ANN). In this paper we present our approach for the design of this tool. The first difficulty lies in choosing the representation of physiological signals and mainly the electroencephalogram (EEG). Once the representation adopted, the next step is to design optimal neural network determined by a learning and validation process applied on data from a set of nights of sleep records. The result obtained with a rate of 63% of good classification for six sleep stages, encourages us to further study this issue at the representation and design levels to improve the performance of our tool.
