Fuzzy Prediction for Traffic Flow Based on Delta Test

Table 3

Evaluation of the impact of the input dimension on the prediction by varying the dimension from 1 to 10 for the one-week traffic flow (RMSEs averaged over 100 independent runs are presented, and denote the RMSE values obtained from training and prediction, resp., and presents the RMSEs for prediction over those for training).
