WebJun 16, 2024 · SVM has a technique called the kernel trick. These are functions that take low dimensional input space and transform it into a higher-dimensional space i.e. it converts not separable problem to separable problem. It is mostly useful in non-linear separation problems. This is shown as follows: Image Source: image.google.com WebJan 24, 2024 · Finally, feature selection is made with the ReliefF algorithm, among many fusion features, and these selected features are classified by SVM. At the end of the study, all these results are compared. According to the results, the CNN-SVM structure with selected fusion features provides more successful diabetes prediction than others.
