Method Detail

setState

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

Specified by:

setState in interface GradientUpdater<RmsProp>

getState

public Map<String,INDArray> getState()

Specified by:

getState in interface GradientUpdater<RmsProp>

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<RmsProp>

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)

Description copied from interface: GradientUpdater

Modify the gradient to be an update. Note that this is be done in-place

Specified by:

applyUpdater in interface GradientUpdater<RmsProp>

Parameters:

gradient - the gradient to modify
