pyntbci.utilities.find_worst_neighbour(score: ndarray[Any, dtype[_ScalarType_co]], neighbours: ndarray[Any, dtype[_ScalarType_co]], layout: ndarray[Any, dtype[_ScalarType_co]]) → tuple[tuple[int, int], float]

Find the neighbouring pair with maximum score.

Parameters:

• score (NDArray) – The matrix of scores of shape (n_codes, n_codes).

• neighbours (NDArray) – The matrix of neighbouring pairs of shape (n_pairs, 2).

• layout (NDArray) – The vector mapping positions to identities of shape (n_codes).

Returns:

• idx (tuple[int, int]) – The two indexes of the neighbouring codes in the layout that have a maximum score.

• val (float) – The maximum score.
