tfa.metrics.hamming_distance

Computes hamming distance.

tfa.metrics.hamming_distance(
    actuals: tfa.types.TensorLike,
    predictions: tfa.types.TensorLike
) -> tf.Tensor

Hamming distance is for comparing two binary strings. It is the number of bit positions in which two bits are different.

actuals actual target value.
predictions predicted value.

hamming distance: float.

Usage:

y_true = np.array([1, 1, 0, 0, 1, 0, 1, 0, 0, 1], dtype=np.int32)
y_pred = np.array([1, 0, 0, 0, 1, 0, 0, 1, 0, 1], dtype=np.int32)
hamming_distance(y_true, y_pred).numpy()
0.3
