示例1: testAccuracy
import it.uniroma2.sag.kelp.predictionfunction.regressionfunction.UnivariateRegressionFunction; //导入依赖的package包/类
@Test
public void testAccuracy() {
LibLinearRegression libLinear = new LibLinearRegression(property, 1, 0.1f, REPRESENTATION_NAME);
libLinear.learn(trainset);
UnivariateRegressionFunction regressor = (UnivariateRegressionFunction) libLinear.getPredictionFunction();
float meanSquaredError = 0;
for(Example ex : testset.getExamples()){
UnivariateRegressionOutput pred = regressor.predict(ex);
float realValue = ex.getRegressionValue(property);
float predictedValue = pred.getScore(property);
meanSquaredError+=(realValue-predictedValue)*(realValue-predictedValue);
}
meanSquaredError/=testset.getNumberOfExamples();
Assert.assertTrue(meanSquaredError<=35.4973 + 0.0001f);
