Python L2Penalty Examples

Example #1

def test_LinearRegressionModel_get_obj_equals_get_obj_jac_l2_penalty():
    _check_get_obj_equals_get_obj_jac(lambda a, o: LinearRegressionModel(
        a,
        o,
        penalty_func=error.L2Penalty(penalty_weight=random.uniform(0.0, 2.0))))

Example #2

def test_L2Penalty_jacobian():
    penalty_func = error.L2Penalty(penalty_weight=random.uniform(0.0, 2.0))
    helpers.check_gradient(penalty_func, penalty_func.derivative)

Example #3

def test_LinearRegressionModel_jacobian_l2_penalty():
    _check_jacobian(lambda a, o: LinearRegressionModel(
        a,
        o,
        penalty_func=error.L2Penalty(penalty_weight=random.uniform(0.0, 2.0))))
