چکیده
The backpropagation algorithm is widely used for training multilayer neural networks In this publication the gain of its activation function s is investigated In speci c it is proven that changing the gain of the activation function is equivalent to changing the learning rate and the weights This simpli es the backpropagation learning rule by eliminating one of its parameters The theorem can be extended to hold for some well known variations on the backpropagation algorithm such as using a momentum term at spot elimination or adaptive gain Furthermore it is successfully applied to compensate for the non standard gain of optical sigmoids for optical neural networks

متن کاملPrediction of Gain in LD-CELP Using Hybrid Genetic/PSO-Neural Models
In this paper, the gain in LD-CELP speech coding algorithm is predicted using three neural models, that are equipped by genetic and particle swarm optimization (PSO) algorithms to optimize the structure and parameters of neural networks. Elman, multi-layer perceptron (MLP) and fuzzy ARTMAP are the candidate neural models. The optimized number of nodes in the first and second hidden layers of El...
