verse.utils.utils.confidence_polytope

verse.utils.utils.confidence_polytope(data: dict, parameter_box: ndarray) → Tuple[ndarray, ndarray, ndarray, float]

Compute a confidence polytope over the parameter theta, where y = theta^T phi

Parameters:

• data – a dictionary {“features”: [phi_0,…,phi_N], “outputs”: [y_0,…,y_N]}

• parameter_box – a box [theta_min, theta_max] containing the parameter theta

Returns:

estimated theta, polytope vertices, Gramian matrix G_N_lambda, radius beta_N
