fatf.utils.distances.hamming_distance

fatf.utils.distances.hamming_distance(x, y, **kwargs)[source]

Computes the Hamming distance between 1-dimensional non-numerical arrays.

Each of the input arrays can be either a 1D numpy array or a row of a structured numpy array, i.e. numpy’s void.

Parameters
xUnion[numpy.ndarray, numpy.void]

The first numpy array (has to be 1-dimensional and non-numerical).

yUnion[numpy.ndarray, numpy.void]

The second numpy array (has to be 1-dimensional and non-numerical).

**kwargsboolean

Keyword arguments that are passed to the fatf.utils.distances.hamming_distance_base function responsible for calculating the Hamming distance.

Returns
distanceUnion[integer, float]

Hamming distance between the two numpy arrays.

Raises
IncorrectShapeError

Either of the input arrays is not 1-dimensional or they are of a different length.

ValueError

Either of the input arrays is not purely textual.
