 The maximum step size.
 
void set_step_size (Float t)
 The starting step size.
 
void set_threshold (Float t)
 Set the minimum gradient threshold.
 

Detailed Description

Follow the gradient based on the partial derivatives. Multiply by the current step size. If the score gets worse, reduce the step size. If the score gets better, increase the step size if we are sufficiently far from a score of zero. If the score reaches the threshold, quit.
