HopfieldLogic

public HopfieldLogic()

Method Detail

addPattern

public void addPattern(NeuralData pattern)

Train the neural network for the specified pattern. The neural network can be trained for more than one pattern. To do this simply call the train method more than once.

Parameters:

pattern - The pattern to train for.

run

public void run()

Perform one Hopfield iteration.

runUntilStable

public int runUntilStable(int max)

Run the network until it becomes stable and does not change from more runs.

Parameters:

max - The maximum number of cycles to run before giving up.

Returns:

The number of cycles that were run.
