virtual void itk::GradientDescentOptimizerBasev4Template< TInternalComputationValueType >::ModifyGradientByLearningRate ( )
virtual

Modify the gradient in place, to advance the optimization. This call performs a threaded modification for transforms with local support (assumed to be dense). Otherwise the modification is performed w/out threading. See EstimateLearningRate() to perform optionaly learning rate estimation. At completion, m_Gradient can be used to update the transform parameters. Derived classes may hold additional results in other member variables.

EstimateLearningRate()
template<typename TInternalComputationValueType >
virtual void itk::GradientDescentOptimizerBasev4Template< TInternalComputationValueType >::ModifyGradientByLearningRateOverSubRange ( const IndexRangeType subrange)
pure virtual

Derived classes define this worker method to modify the gradient by learning rates. Modifications must be performed over the index range defined in subrange. Called from ModifyGradientByLearningRate(), either directly or via threaded operation. This function is used in GradientDescentOptimizerBasev4ModifyGradientByScalesThreaderTemplate and GradientDescentOptimizerBasev4ModifyGradientByLearningRateThreaderTemplate classes.

Implemented in itk::GradientDescentOptimizerv4Template< TInternalComputationValueType >, and itk::RegularStepGradientDescentOptimizerv4< TInternalComputationValueType >.

template<typename TInternalComputationValueType >
ConvergenceMonitoringType::Pointer itk::GradientDescentOptimizerBasev4Template< TInternalComputationValueType >::m_ConvergenceMonitoring

template<typename TInternalComputationValueType >
SizeValueType itk::GradientDescentOptimizerBasev4Template< TInternalComputationValueType >::m_ConvergenceWindowSize

Window size for the convergence checker. The convergence checker calculates convergence value by fitting to a window of the energy (metric value) profile.

template<typename TInternalComputationValueType >
bool itk::GradientDescentOptimizerBasev4Template< TInternalComputationValueType >::m_DoEstimateLearningRateOnce

template<typename TInternalComputationValueType >
TInternalComputationValueType itk::GradientDescentOptimizerBasev4Template< TInternalComputationValueType >::m_MaximumStepSizeInPhysicalUnits
protected

The maximum step size in physical units, to restrict learning rates. Only used with automatic learning rate estimation. It may be initialized either by calling SetMaximumStepSizeInPhysicalUnits manually or by using m_ScalesEstimator automatically, and the former has higher priority than the latter. See main documentation.
