Slanted triangle learning rate. The curve of learning rate is similar to a triangle, and its expression is shown in Eqs. 22–24, where T is the total number of training iterations, \(cut_ Frac\) is the percentage of rising segment to the total number of iterations, and ratio determines the lowest value of learning rate. In the experiment, we set \(cut_Frac=0.1\), \(ratio=32\), \(\eta _{max}=0.1\)
