public class BPLearn

extends BWButton

Button that implements the Backpropagation learning algorithm.

Each cycle of the algorithm involves the following steps:

1. Instantiate the current pattern.
2. Feedforward these activations to calculate the output of the network.
3. Calculate the errors on each of the output units by comparing the current output with the target output specified in the Output set.
4. Feedback the errors to calculate Delta values for each of the units. The Delta value is essentially how much that unit is to blame for the errors.
5. Update the weights based on the current Deltas and activations of the from units.
