In fact, the calculation of numerical methods can not take advantage of the previous useful information, each derivative needs to be calculated independently, the calculation can not be simplified.But the interesting thing is that the numerical derivative is useful in another place--gradient check! We can use the results of the central differences and the derivative of the BP algorithm to compare, in order to determine whether the BP algorithm execution is correct.Starting today to
