Detailed Description

template<class TElastix>
class elastix::RSGDEachParameterApart< TElastix >

An optimizer based on gradient descent.

The underlying itk class is almost a copy of the normal RegularStepGradientDescent. The difference is that each parameter has its own step length, whereas the normal RSGD has one step length that is used for all parameters.

This could cause inaccuracies, if, for example, parameter 1, 2 and 3 are already close to the optimum, but parameter 4 not yet. The average stepsize is halved then, so parameter 4 will not have time to reach its optimum (in a worst case scenario).

The RSGDEachParameterApart stops only if ALL steplenghts are smaller than the MinimumStepSize given in the parameter file!

The elastix shell class (so, this class...), is a copy of the elxRegularStepGradientDescent, so the parameters in the parameter file, the output etc are similar.

The parameters used in this class are:

Parameters:
Optimizer: Select this optimizer as follows:
(Optimizer "RSGDEachParameterApart")
Parameters:
MaximumNumberOfIterations: the maximum number of iterations in each resolution.
example: (MaximumNumberOfIterations 100 100 50)
Default value: 100.
Parameters:
MinimumGradientMagnitude: stopping criterion. If the magnitude of the derivative of the cost function is below this value, optimisation is stopped.
example: (MinimumGradientMagnitude 0.0001 0.0001 0.001)
Default value: 1e-8.
Parameters:
MinimumStepLength: stopping criterion. If the steplength is below this value, optimisation is stopped.
example: (MinimumStepLength 1.0 0.5 0.1)
Default value: 0.5 / 2^resolutionlevel
Parameters:
MaximumStepLength: the starting steplength.
example: (MaxiumStepLength 16.0 8.0 4.0)
Default value: 16 / 2^resolutionlevel.
