tf.keras.losses.MSE

TensorFlow 1 version View source on GitHub

Computes the mean squared error between labels and predictions.

tf.keras.losses.MSE(
    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)

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)) 

Args:

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

Returns:

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