Various activation functions in hidden layers and output layers are compared in order to find and to select the best activation function. It is found that the use of Hyperbolic tangent-function for the hidden layers, and Linear activation function for the output layer gives the most satisfactory ...
e performance has been evaluated by varying the activation function in the hidden and output layers with the developed functions for single and multilayer networks. 1. Introduction An activation function in the neural network determines whether the neuron's inputs to the network are relevant or not...
Both linear and non linear methods of analysis were used. The former allow the comparison of findings with earlier reports, although the latter seems to be more appropriate to the analysis of complex systems like biological phenomena63. Results ...
