“…There is not an ideal classification algorithm that outperforms the others as it depends on the dataset, image segmentation, and feature extraction (see Figure 9 ); however, in the literature, some of them have been found to provide better discrimination among skin lesions. Support Vector Machine (SVM) is the most applied classifier, as it shows the best performance [ 107 , 109 , 110 , 111 , 112 , 114 , 115 , 116 , 117 , 118 ] followed by k-Nearest Neighbors (KNN) [ 65 , 106 , 107 , 108 , 109 , 110 , 111 , 116 , 117 , 118 ], Neural Networks (NN) [ 110 , 114 , 115 , 117 , 119 ], Random Forest (RF) [ 107 , 109 , 113 , 114 ] and Decision Trees (DT) [ 65 , 109 , 110 , 111 , 117 , 118 ]. SVMs are based on statistics to build hyperplanes that maximize the distance between sets of data points [ 120 , 121 ].…”
