fann_init_weights — Initialize the weights using Widrow + Nguyen’s algorithm
Descrição
Initialize the weights using Widrow + Nguyen’s algorithm.
This function behaves similarly to fann_randomize_weights(). It will use the algorithm developed by Derrick Nguyen and Bernard Widrow to set the weights in such a way as to speed up training. This technique is not always successful, and in some cases can be less efficient than a purely random initialization.
The algorithm requires access to the range of the input data (for example largest and smallest input), and therefore accepts a second argument, data, which is the training data that will be used to train the network.
