tf.keras.metrics.mean_squared_logarithmic_error(
    y_true, y_pred
)

loss = mean(square(log(y_true + 1) - log(y_pred + 1)), 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_logarithmic_error(y_true, y_pred)
assert loss.shape == (2,)
y_true = np.maximum(y_true, 1e-7)
y_pred = np.maximum(y_pred, 1e-7)
assert np.allclose(
    loss.numpy(),
    np.mean(
        np.square(np.log(y_true + 1.) - np.log(y_pred + 1.)), 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 logarithmic error values. shape = [batch_size, d0, .. dN-1].
