tf.contrib.losses.cosine_distance(
    predictions,
    labels=None,
    axis=None,
    weights=1.0,
    scope=None,
    dim=None
)

Defined in tensorflow/contrib/losses/python/losses/loss_ops.py.

Adds a cosine-distance loss to the training procedure. (deprecated arguments) (deprecated)

Note that the function assumes that predictions and labels are already unit-normalized.

Args:

• predictions: An arbitrary matrix.
• labels: A Tensor whose shape matches 'predictions'
• axis: The dimension along which the cosine distance is computed.
• weights: Coefficients for the loss a scalar, a tensor of shape [batch_size] or a tensor whose shape matches predictions.
• scope: The scope for the operations performed in computing the loss.
• dim: The old (deprecated) name for axis.

Returns:

A scalar Tensor representing the loss value.

Raises:

• ValueError: If predictions shape doesn't match labels shape, or weights is None.
