ant colony optimization algorithm support vector machine parameter optimization oil analysis fault diagnosis
Parameters of support vector machine is the key factor that impacts its classifying performance.A parameter optimization method for support vector machine using ant colony optimization algorithm is discussed.A parameter optimization model is established.The continuous ant colony optimization method based on gridding partition is given and used to resolve the optimization model.The classifying performance reaches the best state by optimizing the penalty factor and the radial basis function.The validity of the method is tested by simulation and application instances,and more than 95% classified right rate is obtained.
