Constructor Detail

ErrorBasedConvergenceObserver

public ErrorBasedConvergenceObserver()

Creates a new instance of ErrorBasedConvergenceObserver

Method Detail

setPercentage

public void setPercentage(double aPercentage)

Sets the percentage. Whenever a neural network's training error doesn't decrease more than this percentage for a couple of steps in a sequence of training errors, the network is considered as converged.

Parameters:

aPercentage - the percentage to set.

getPercentage

public double getPercentage()

Gets the percentage.

Returns:

the percentage.

setCycles

public void setCycles(int aCylces)

Sets the number of cycles. Whenever the training error of a network doesn't decrease more than a percentage for this number of cycles, the network is considered as converged.

Parameters:

aCylces -

getCycles

public int getCycles()

Gets the number of cycles over which convergence is checked.

Returns:

the number of cycles.
