SVM classification and -means clustering results by the DCTMSB approach of the proposed MSB-based scheme. Note that the distance between support vectors by SVM [27] is and cluster 1 and cluster 2 are positive and negative clusters, respectively, by -means clustering algorithm [28]. Attack numbers 0–9 are referred using Table 3.
