Method Detail

hasStepSizeReductionExponent

boolean hasStepSizeReductionExponent()

 The step size reduction exponent defines a step size given by
 (1 - (total_steps_attempted + 1)^(-step_size_reduction_exponent)) *
 step_size_limit where step_size_limit is the maximum allowed step size at
 the current iteration. This should be between 0.1 and 1.
 

optional double step_size_reduction_exponent = 1 [default = 0.3];

Returns:

Whether the stepSizeReductionExponent field is set.

getStepSizeReductionExponent

double getStepSizeReductionExponent()

 The step size reduction exponent defines a step size given by
 (1 - (total_steps_attempted + 1)^(-step_size_reduction_exponent)) *
 step_size_limit where step_size_limit is the maximum allowed step size at
 the current iteration. This should be between 0.1 and 1.
 

optional double step_size_reduction_exponent = 1 [default = 0.3];

Returns:

The stepSizeReductionExponent.

hasStepSizeGrowthExponent

boolean hasStepSizeGrowthExponent()

 The step size growth exponent defines a step size given by (1 +
 (total_steps_attempted + 1)^(-step_size_growth_exponent)) * step_size_.
 This should be between 0.1 and 1.
 

optional double step_size_growth_exponent = 2 [default = 0.6];

Returns:

Whether the stepSizeGrowthExponent field is set.

getStepSizeGrowthExponent

double getStepSizeGrowthExponent()

 The step size growth exponent defines a step size given by (1 +
 (total_steps_attempted + 1)^(-step_size_growth_exponent)) * step_size_.
 This should be between 0.1 and 1.
 

optional double step_size_growth_exponent = 2 [default = 0.6];

Returns:

The stepSizeGrowthExponent.
