Class ResetStrategy

java.lang.Object
  org.encog.ml.train.strategy.ResetStrategy

All Implemented Interfaces:

Strategy

public class ResetStrategy
extends Object
implements Strategy

The reset strategy will reset the weights if the neural network fails to fall below a specified error by a specified number of cycles. This can be useful to throw out initially "bad/hard" random initializations of the weight matrix.

Constructor Detail

ResetStrategy

public ResetStrategy(double required,
                     int cycles)

Construct a reset strategy. The error rate must fall below the required rate in the specified number of cycles, or the neural network will be reset to random weights and bias values.

Parameters:

required - The required error rate.

cycles - The number of cycles to reach that rate.

train - The training algorithm.

postIteration

public void postIteration()

Called just after a training iteration.

Specified by:

postIteration in interface Strategy

preIteration

public void preIteration()

Called just before a training iteration.
