Clear Metrics Description

With CFG.NULL_VAL = 0.0, three metrics (MAE, RMSE, MAPE) are defaulted as masked ones. Maybe you should use Masked XXX instead of XXX in experimental results?

Hi thanks for you suggestions.
The “0” is the abnormal value for traffic datasets. Thus, the “MAE” we wanted is indeed the masked ones, since calculating errors on abnormal values and forcing models to fit these abnormal data does not make any sense. Almost all the previous works followed this setting and reported these metrics without the “masked”.
Moreover, the default null value of these metrics is nan, instead of 0.0, since in many datasets the “0” is not abnormal values.
