def slice_index_list_by_class(...)

def slice_index_list_by_class(classes: Union[npt.NDArray, list], y: npt.NDArray) -> dict

The function slice_index_list_by_class(...), separates the indices of the lines \ according to the output class, to loop through the sample array, only in positions where \ the output is the class being trained.

Parameters:

• classes (list or npt.NDArray): list with unique classes.
• y (npt.NDArray): Receives a y[N sample] array with the output classes of the X sample array.

returns:

• dict: A dictionary with the list of array positions(y), with the classes as key.
