(1) SVM is specifically designed for small-sample problems, capable of obtaining optimal solutions with limited data samples; (2) The SVM algorithm ultimately transforms into a quadratic programming problem, theoretically yielding global optimal solutions and overcoming local optimality issues inherent in traditional neural networks; (3) SVM's topology is determined by support vectors, eliminating the trial-and-error approach required for determining network structures in traditional neural networks. The implementation involves optimizing margin constraints through convex optimization techniques.
