The average value of absoluteerror is 2.05% and the biggest error is 5.12% in the model of loom efficiency. The results indicate that ANN model has high forecast precision.
The result showed averageabsoluteerror is 0.17% and average relative error is 8.58%. It is concluded that self-made TDR probe can be used in the other area of Loess Plateau.
Some forecasting procedures sum the absolute values of the errors and may report this sum, or divide it by the number of forecast attempts to produce the average forecast error.
