“…The classification results for the different number of dilation factors are shown in Figure 18. In this experiment, seven kinds of combination for the dilation factors were considered including: (1), (1,2), (1,2,3), (1,2,3,4), (1,2,3,4,5), (1,2,3,4,5,6) and (1,2,3,4,5,6,7), and 30 samples per class were selected as training samples. With the increasing of number dilation factors, the classification accuracy also improves.…”
