Python mean_scaling Examples

Example #1

def test_scaling():
    """Test the scaling function"""
    shape = (400, 10)
    u = np.random.randn(*shape)
    mean = 100 * np.random.rand(shape[1]) + 1
    Y = u + mean
    Y_, mean_ = mean_scaling(Y)
    assert_almost_equal(Y_.mean(0), 0, 5)
    assert_almost_equal(mean_, mean, 0)
    assert Y.std() > 1
