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.
As the name suggests, the mean absoluteerror is an average of the absolute errors, where is the prediction and the true value.
顾名思义，平均绝对误差是绝对误差的平均值，其中fi是预测值而yi是实际值。

The experimental results show that the absolutevalue of mean error of such prediction and control precision is within 5% , which gets good effect on sheet shape control. The BP network m…
