Abstract

Abstract: Aiming at the problem of the training data set with large samples, high dimension, and complex features, a self-adaptive multiple kernel learning algorithm was proposed by integrating support vector machine with ant colony optimization algorithm. The affinity propagation clustering algorithm was used to find the similar features adaptively, and then the parameters of the kernel function were selected adaptively by ant colony algorithm, so as to select the optimal kernel function quikly. Experimental results of five groups of UCI data sets show that the proposed algorithm has higher classification accuracy and F₁ value than the traditional support vector machine, which verifies the effectiveness and feasibility of the proposed algorithm.

Key words: multiple kernel learning, support vector machine, ant colony algorithm, clustering algorithm
