Abstract

---

This paper analyses the suitability to include hyperbolic tangent units within neural networks based on Multilayer Perceptron (MLP) trained by means of a back propagation algorithm. The experimentation is conducted out in classical problems from the scope of health and also with data sets from high dimensional domains. As a main conclusion could be drawn that hyperbolic tangent are very handy. On the other hand, the training of this kind of neural networks is a drawback. The setting of the parameters is an issue. The results, compared to those of sigmoid activation function, are very promising and very often better. This is the starting point to design other kind of activation functions.
