fann_init_weights
FANN_INIT_WEIGHTS(3) 1 FANN_INIT_WEIGHTS(3)
fann_init_weights - Initialize the weights using Widrow + Nguyen's algorithm
SYNOPSIS
bool fann_init_weights (resource $ann, resource $train_data)
DESCRIPTION
Initialize the weights using Widrow + Nguyen's algorithm.
This function behaves similarly to fann_randomize_weights(3). 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.
PARAMETERS
o $ann
-Neural network resource.
o $train_data
-Neural network training data resource.
RETURN VALUES
Returns TRUE on success, or FALSE otherwise.
SEE ALSO
fann_randomize_weights(3), fann_read_train_from_file(3).
