FIGURE 3.
Performance of different kinds features on SVM, CNN, and C4.5. Cyan, orange, gray, yellow, blue, and green, respectively, represent the performance of 3-mer, 4-mer, 5-mer, 6-mer, 7-mer, and 8-mer embedding features. Purple, pink, and red, respectively, represent the performance of 4, 5, 6-mer concatenated embeddings, 6, 7, 8-mer concatenated embeddings, and 3, 4, 5, 6, 7, 8-mer concatenated embeddings. (A,B) Performance of different kinds of feature on SVM. The standard deviation of SVM on 3-mer, 4-mer, 5-mer, 6-mer, 7-mer, 8-mer, 4, 5, 6-mer, 6, 7, 8-mer, and 3, 4, 5, 6, 7, 8-mer is in the range (0.001, 0.003), (0.001, 0.003), (0.001, 0.003), (0.001, 0.003), (0.001, 0.003), (0.001, 0.004), (0.001, 0.004), (0.001, 0.003), and (0.001, 0.003); (C,D) Performance of different kinds of feature on CNN. The standard deviation of CNN on 3-mer, 4-mer, 5-mer, 6-mer, 7-mer, 8-mer, 4, 5, 6-mer, 6, 7, 8-mer, and 3, 4, 5, 6, 7, 8-mer is in the range (0.003, 0.026), (0.008, 0.071), (0.006, 0.049), (0.015, 0.056), (0.016, 0.055), (0.016, 0.059), (0.008, 0.044), (0.011, 0.058), and (0.008, 0.045); (E,F) Performance of different kinds of features on C4.5. The standard deviation of CNN on 3-mer, 4-mer, 5-mer, 6-mer, 7-mer, 8-mer, 4, 5, 6-mer, 6, 7, 8-mer, and 3, 4, 5, 6, 7, 8-mer is in the range (0.005, 0.545), (0.007, 0.531), (0.005, 0.049), (0.007, 0.685), (0.003, 0.440), (0.007, 0.489), (0.008, 0.630), (0.006, 0.567), and (0.005, 0.518).
