 This paper proposes a new search strategy using imitative scale chaos optimization algorithm (MSCO) for model selection of support vector machine (SVM). Model selection for svm using imitative scale chaos optimization algorithm The chaos optimization algorithm was used to help the gradient regularization method to escape from local optima in the hybrid algorithm.
