Scaling data around zero is important to avoid numerical issues when fitting a machine learning model. This is all the more true as the variables have different ranges or the fitting relies on numerical optimization techniques. This example illustrates the latter point.

First, we consider the Rosenbrock function \(f(x)=(1-x_1)^2+100(x_2-x_1^2)^2\) over the domain \([-2,2]^2\):

problem = Rosenbrock()

In order to approximate this function with a regression model, we sample it 30 times with an optimized Latin hypercube sampling (LHS) technique

Then, we create a first Gaussian process regressor from the training dataset:

gpr = GaussianProcessRegressor(dataset_train)
gpr.learn()

and compute its R2 quality from the test dataset:

r2 = R2Measure(gpr)
r2.compute_test_measure(dataset_test)
array([0.97049746])

Then, we create a second Gaussian process regressor from the training dataset with the default input and output transformers that are MinMaxScaler:

gpr = GaussianProcessRegressor(
    dataset_train, transformer=GaussianProcessRegressor.DEFAULT_TRANSFORMER
)
gpr.learn()

We can see that the scaling improves the R2 quality (recall: the higher, the better):

r2 = R2Measure(gpr)
r2.compute_test_measure(dataset_test)
array([0.97049746])

We note that in this case, the input scaling does not contribute to this improvement:

gpr = GaussianProcessRegressor(dataset_train, transformer={"outputs": "MinMaxScaler"})
gpr.learn()
r2 = R2Measure(gpr)
r2.compute_test_measure(dataset_test)
array([0.97049746])

We can also see that using a StandardScaler is less relevant in this case:

gpr = GaussianProcessRegressor(dataset_train, transformer={"outputs": "StandardScaler"})
gpr.learn()
r2 = R2Measure(gpr)
r2.compute_test_measure(dataset_test)
array([0.97049746])

Finally, we rewrite the Rosenbrock function as \(f(x)=(1-x_1)^2+100(0.01x_2-x_1^2)^2\) and its domain as \([-2,2]\times[-200,200]\):

design_space = DesignSpace()
design_space.add_variable("x1", lower_bound=-2, upper_bound=2)
design_space.add_variable("x2", lower_bound=-200, upper_bound=200)

in order to have inputs with different orders of magnitude. We create the learning and test datasets in the same way:

problem = OptimizationProblem(design_space)
problem.objective = MDOFunction(
    lambda x: (1 - x[0]) ** 2 + 100 * (0.01 * x[1] - x[0] ** 2) ** 2, "f"
)
opt_lhs.execute(problem, n_samples=30)
dataset_train = problem.to_dataset(opt_naming=False)
full_fact.execute(problem, n_samples=30 * 30)
dataset_test = problem.to_dataset(opt_naming=False)

and build a first Gaussian process regressor with a min-max scaler for the outputs:

gpr = GaussianProcessRegressor(dataset_train, transformer={"outputs": "MinMaxScaler"})
gpr.learn()
r2 = R2Measure(gpr)
r2.compute_test_measure(dataset_test)
array([0.90669624])

The R2 quality is degraded because estimating the model's correlation lengths is complicated. This can be facilitated by setting a MinMaxScaler for the inputs:

gpr = GaussianProcessRegressor(
    dataset_train, transformer={"inputs": "MinMaxScaler", "outputs": "MinMaxScaler"}
)
gpr.learn()
r2 = R2Measure(gpr)
r2.compute_test_measure(dataset_test)
array([0.97432803])
