cosapp.utils.surrogate_models.nn_interpolators.linear_interpolator

Define the LinearInterpolator class.

Classes

LinearInterpolator(training_points, ...[, ...])

Interpolate values by forming a hyperplane between the points closest to the prescribed inputs.

class cosapp.utils.surrogate_models.nn_interpolators.linear_interpolator.LinearInterpolator(training_points, training_values, num_leaves=2)

Bases: NNBase

Interpolate values by forming a hyperplane between the points closest to the prescribed inputs.

gradient(prediciton_points)

Find the gradient at each location of a set of supplied predicted points.

Parameters:

prediciton_points (ndarray) – Prediction points at which the gradient is calculated.

Returns:

Gradient at the prediction points.

Return type:

ndarray
