Abstract

This paper will study the rainfall prediction at Semarang City as time series data with Feed Forward Neural Network (FFNN). The learning algorithm that be used are the Quasi Newton BFGS and Levenberg-Marquardt algorithm. The input unit is determined based on the best of ARIMA model. The computation is done with use Matlab 7.1 program with 1000 epoch, five unit of hidden layer, 100 replication and use input at lag variabel 1, 12 and 13, respectively. The result shows that the prediction is good in relatively, where Quasi Newton BFGS algorithm result the Mean Square Error (MSE) that more accurate. Key Words : FFNN, Quasi Newton BFGS, Levenberg-Marquardt, rainfall
