- Abstract:
-
The least square twin support vector machine (TWSVM) is very sensitive to noise and outlier. To solve this problem, we propose an energy-based structured least square TWSVM (ES-LSTWSVM). First, we perform a cluster analysis on each class, then compute the covariance matrix of each cluster in the classes, and introduce it into the objective function. To reduce the influence of noises and outliers on the algorithm, an energy factor is introduced to each hyperplane, and the equality constraint is converted into an energy-based form on the basis of least squares. Finally, we adopt the “all-versus-one” strategy to apply the proposed algorithm in solving a multi-class classification problem. The experimental results show that ES-LSTWSVM has good classification performance.
