tf.keras.losses.MAE

Computes the mean absolute error between labels and predictions.

Used in the notebooks

Used in the tutorials

loss = mean(abs(y_true - y_pred), axis=-1)

Standalone usage:

y_true = np.random.randint(0, 2, size=(2, 3))
y_pred = np.random.random(size=(2, 3))
loss = tf.keras.losses.mean_absolute_error(y_true, y_pred)
assert loss.shape == (2,)
assert np.array_equal(
    loss.numpy(), np.mean(np.abs(y_true - y_pred), axis=-1))

y_true Ground truth values. shape = [batch_size, d0, .. dN].
y_pred The predicted values. shape = [batch_size, d0, .. dN].

Mean absolute error values. shape = [batch_size, d0, .. dN-1].
