示例1: learnTarget
void AdalineTest::learnTarget(const Vector<double>* targetWeights, Adaline<double>* learner)
{
int nbUpdate = 0;
double threshold = 1e-3;
History<double, 5> history;
history.fill(threshold);
PVector<double> features(targetWeights->dimension());
double target = 0.0f;
while (history.getSum() > threshold)
{
updateFeatures(&features);
target = targetWeights->dot(&features);
double error = learner->predict(&features) - target;
Boundedness::checkValue(error);
history.add(std::fabs(error));
learner->learn(&features, target);
++nbUpdate;
Assert::assertPasses(nbUpdate < 100000);
}
Assert::assertPasses(nbUpdate > 30);
Assert::assertObjectEquals(target, learner->predict(&features), threshold * 10);
