comet_maths.interpolation.interpolation.gpr_basics(x_i: ndarray, y_i: ndarray, x: ndarray, u_y_i: ndarray | None = None, kernel: str | None = 'RBF', min_scale: float | None = 0.01, max_scale: float | None = 10000) → ndarray[source]#

Function to perform basic gaussian process regression

Parameters:

  • x_i – Independent variable quantity x (coordinate data of y_i)

  • y_i – measured variable quantity y (data to interpolate)

  • x – Independent variable quantity x for which we are trying to obtain the measurand y

  • u_y_i – uncertainties on y_i, defaults to None

  • kernel – kernel to be used in the gpr interpolation. Defaults to “RBF”.

  • min_scale – minimum bound on the scale parameter in the gaussian process regression. Defaults to 0.01

  • max_scale – maximum bound on the scale parameter in the gaussian process regression. Defaults to 100

Returns:

The measurand y evaluated at the values x (interpolated data)
