estimate_angles(dataset, angle_sin_strs, angle_cos_strs, angle_name='epsilon', length_list=None, rpeconfig_inst=None)#

For a dataset containing sin and cos strings to estimate either alpha, epsilon, or Phi return a list of alpha, epsilon, or Phi estimates (one for each generation). Note: this assumes the dataset contains ‘0’ and ‘1’ SPAM labels.

Parameters:

  • dataset (DataSet) – The dataset from which the angle estimates will be extracted.

  • angle_sin_strs (list of Circuits) – The list of sin strs that the estimator will use.

  • angle_cos_strs (list of Circuits) – The list of cos strs that the estimator will use.

  • angle_name ({ "alpha", "epsilon", "Phi" }, optional) – The angle to be extracted

  • length_list (The list of sequence lengths. Default is None;) – If None is specified, then length_list becomes [1,2,4,…,2**(len(angle_sin_strs)-1)]

  • rpeconfig_inst (RPEconfig object) – Declares which model configuration RPE should be trying to fit; determines particular functions and values to be used.

Returns:

angleHatList – A list of angle estimates, ordered by generation (k).

Return type:

list of floats
