WebThe main idea of SVC is to map data space to a high-dimensional feature space using a Gaussian kernel function. Next, a sphere with a minimum radius is obtained and the sphere contains most of the mapped data [41,42]. After being mapped back to the data space, the sphere can be separated into several parts, each containing a single cluster ...
