Surrogate Models

Base

saealib.Surrogate	Base class for surrogate models.
saealib.SurrogatePrediction	Unified return type for surrogate model predictions.

Surrogate Managers

saealib.SurrogateManager	Abstract base class for surrogate managers.
saealib.GlobalSurrogateManager	Surrogate manager that fits once on the full archive.
saealib.LocalSurrogateManager	Surrogate manager that fits a local model per candidate (pre-selection).
saealib.EnsembleSurrogateManager	Surrogate manager that aggregates scores from multiple sub-managers.

RBF Surrogate

saealib.RBFsurrogate

Radial Basis Function (RBF) Interpolation surrogate model.

saealib.gaussian_kernel(x1, x2, sigma=2.0)

Gaussian radial basis function kernel.

Parameters:

• x1 (np.ndarray) – Input data 1.

• x2 (np.ndarray) – Input data 2.

• sigma (float) – Kernel width parameter.

Returns:

Matrix of kernel evaluations between x1 and x2. shape: (len(x1), len(x2))

Return type:

np.ndarray
