I try to choose the best model between the Arima
model and the Feed-forward neural networks
.
The script runs well and I use the accuracy
function to compare the to algoritm.
I use the RMSE
to chouse the best model, is enough or I have to compare other parametres?
I'd like to precise that the data set is equal and the numbers are normalization between 0 and 1.
Below the results of the two algorithms:
ARIMA MODEL ME RMSE MAE MPE MAPE MASE ACF1
Training set -2.284042e-06 0.005978466 0.003094135 -Inf Inf 1.006384 -0.0004549235
FEED FORWARD NEURAL NETWORKS MODEL
ME RMSE MAE MPE MAPE MASE ACF1
Training set -7.196957e-06 0.00571893 0.003075926 -Inf Inf 1.000462 0.00461708
In this case I chouse the Feed Forward Neural Network because the RMSE is lower respect the Arima, but my question are:
is enouth lower the RMSE?
I have to do another type of test and consider also it?
Thank in advance for any type of help.
