Computes the mean squared error between labels and predictions.
tf.keras.metrics.mean_squared_error(
y_true, y_pred
)
After computing the squared distance between the inputs, the mean value over the last dimension is returned.
loss = mean(square(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_squared_error(y_true, y_pred)
assert loss.shape == (2,)
assert np.array_equal(
loss.numpy(), np.mean(np.square(y_true - y_pred), axis=-1))
