i need some help for building the best performance ann architecture for rainfall forecasting in a village in indonesia with 360 data (months in 30 years). First of all i am a begin…
I have run Ann for prediction with hidden nodes from 2-17 about 50 times. My question is which criteria I should rely on to select the best Ann? Should I choose R squerd of Test or…
Hello! I'm trying to make a forecast program using neural networks. The training function I'm using is the Bayesian Regularization. Results are pretty good, but when I see the perf…
I've tried to reproduce the results I got from a trained network but was unable. Here's my script: load 'C:\Users\ZA\Documents\cosjacorr.mat' inputs = cosjacorr(:, 1:9)'; tar…
does anybody ever use neural network to do a prediction with regularization optimization instead of early stopping? Hi, everyone, I am trying to train a neural network (NN) for pre…
I'm using MATLAB R2011a. I'm trying to predict next 100 points of time-serie X by means of neural net. Firstly, I create input time series Xtra and feedback time series Ytra: …
