Method Detail

setState

public void setState(Map<String,INDArray> stateMap,
                     boolean initialize)

Specified by:

setState in interface GradientUpdater<AdaDelta>

getState

public Map<String,INDArray> getState()

Specified by:

getState in interface GradientUpdater<AdaDelta>

setStateViewArray

public void setStateViewArray(INDArray viewArray,
                              long[] gradientShape,
                              char gradientOrder,
                              boolean initialize)

Description copied from interface: GradientUpdater

For the internal updater state (if any): set this to use the provided array. Used during initialization, and when restoring the updater state (after serialization, for example)

Specified by:

setStateViewArray in interface GradientUpdater<AdaDelta>

Parameters:

viewArray - Array (that is a view of a larger array) to use for the state.

initialize - If true: the updater must initialize the view array. If false: no change to view array contents

applyUpdater

public void applyUpdater(INDArray gradient,
                         int iteration,
                         int epoch)

Get the updated gradient for the given gradient and also update the state of ada delta.

Specified by:

applyUpdater in interface GradientUpdater<AdaDelta>

Parameters:

gradient - the gradient to get the updated gradient for

iteration -
