Relax the requirements on loss functiond derivatives. We now require that the first derivative of the loss function be positive only if the second derivative is non-zero. This is because when the second derivative is non-positive, we do not use the second order correction suggested by BANS and instead use a simpler first order strategy which does not use a division by the gradient of the loss function.
