8.9.10. sklearn.gaussian_process.regression_models.quadratic

sklearn.gaussian_process.regression_models.quadratic(x)

Second order polynomial (quadratic, p = n*(n-1)/2+n+1) regression model.

x –> f(x) = [ 1, { x_i, i = 1,...,n }, { x_i * x_j, (i,j) = 1,...,n } ].T

i > j

Parameters :

x : array_like

An array with shape (n_eval, n_features) giving the locations x at which the regression model should be evaluated.

Returns :

f : array_like

An array with shape (n_eval, p) with the values of the regression model.
