present, the common solution is to pre-edit the known sample points in advance to remove the small sample of the role of classification.5 Advantages and disadvantages of support vector machine (SVM)Advantages of SVM: * *One, can solve the problem of machine learning in the case of small samples.Second, can improve the generalization performance.Thirdly, we can solve the problem of high dimension.Four, can solve the nonlinear problem.Five, can avoid the neural network structure choice and the lo

Its advantages are easy to implement, calculation (training and classification) is particularly simple, it is commonly used to measure the performance of the classification system of the benchmark system, and the practical classification system rarely use this algorithm to solve specific classification problems.
