Table 1 Selected Feature Set
Figure 1. (a) The classification accuracy and (b) running time of KNN with respect to different K, and (c) the relationship between running time and accuracy of the best performance of each of six feature combinations
Figure 4 shows the performance of RF with different number of trees in the forest. Obviously, the accuracy of RF maintained increasing along with the growth of quantity of trees until a flat trend
