fann_init_weights
  Initialize the weights using Widrow + Nguyen’s algorithm
  
 
  説明
  
   bool fann_init_weights(resource $ann, resource $train_data)
  
  
   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.
