fann_init_weights - Initialize the weights using Widrow + Nguyen’s algorithm
Manual
fann_init_weights(
resource$ann,
resource$train_data ): bool
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.
Parameters
- ann
-
Neural network resource.
- train_data
-
Neural network training data resource.
Return Values
Returns true on success, or false otherwise.
