示例1: EvoSVMModel

import com.rapidminer.tools.math.kernels.DotKernel; //导入依赖的package包/类
/** Creates a classification model. */
public EvoSVMModel(ExampleSet exampleSet, List<SupportVector> supportVectors, Kernel kernel, double bias) {
	super(exampleSet, ExampleSetUtilities.SetsCompareOption.ALLOW_SUPERSET,
			ExampleSetUtilities.TypesCompareOption.ALLOW_SAME_PARENTS);
	this.supportVectors = supportVectors;
	if (supportVectors == null || supportVectors.size() == 0) {
		throw new IllegalArgumentException("Null or empty support vector collection: not possible to predict values!");
	}
	this.kernel = kernel;
	this.bias = bias;

	if (this.kernel instanceof DotKernel) {
		this.weights = new double[getNumberOfAttributes()];
		for (int i = 0; i < getNumberOfSupportVectors(); i++) {
			SupportVector sv = getSupportVector(i);
			if (sv != null) {
				double[] x = sv.getX();
				double alpha = sv.getAlpha();
				double y = sv.getY();
				for (int j = 0; j < weights.length; j++) {
					weights[j] += y * alpha * x[j];
				}
			} else {
