bayesvalidrox.surrogate_models.surrogate_models.create_psi¶

bayesvalidrox.surrogate_models.surrogate_models.create_psi(basis_indices, univ_p_val)¶

This function assemble the design matrix Psi from the given basis index set INDICES and the univariate polynomial evaluations univ_p_val.

Parameters¶

basis_indicesarray of shape (n_terms, n_params): Multi-indices of multivariate polynomials.
univ_p_valarray of (n_samples, n_params, n_max+1): All univariate regressors up to n_max.

Raises¶

ValueError: n_terms in arguments do not match.

Returns¶

psiarray of shape (n_samples, n_terms): Multivariate regressors.
