VectorizedBackTrackLineSearchMinimum

public VectorizedBackTrackLineSearchMinimum(OptimizableByGradientValueMatrix optimizable)

Method Detail

setStpmax

public void setStpmax(double stpmax)

getStpmax

public double getStpmax()

setRelTolx

public void setRelTolx(double tolx)

Sets the tolerance of relative diff in function value. Line search converges if abs(delta x / x) < tolx for all coordinates.

setAbsTolx

public void setAbsTolx(double tolx)

Sets the tolerance of absolute diff in function value. Line search converges if abs(delta x) < tolx for all coordinates.

optimize

public double optimize(INDArray line,
                       int lineSearchIteration,
                       INDArray g,
                       INDArray params)
