“…Support vector machine is a type of machine learning algorithm, which aims at finding one optimal hyperplane to make two kinds of training data as far as possible away from the hyperplane in the high dimensional space [1].It has great advantages of solving small sample, nonlinear and high dimensional pattern recognition problem, therefore, its been successfully applied to many aspects, such as, medical image detection [2], network information classification [3,4], pattern recognition [5], etc. Classical SVM needs to solving a Quadratic Programming Problem (QPP), which computational complexity is O(l3)(l refers to the total number of training data), so when dealing with large-scale data is restricted.…”
