Perform predictive data in the form of time series required a correct method, one method is now often used is the propagation of this method is a method that is able to minimize the error value of the output of the predicted number of people, but still generate quite a lot of iteration that needs to be optimized by minimize iterations and use of time, then the use of conjugate gradient polak Ribiere are expected to minimize the use of time, the number of the epoch of the results of standard backpropagation.
