Function fann_sys::fann_init_weights

pub unsafe extern "C" fn fann_init_weights(
    ann: *mut fann, 
    train_data: *mut fann_train_data
)

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 (ie, largest and smallest input), and therefore accepts a second argument, data, which is the training data that will be used to train the network.
