tfa.losses.lifted_struct_loss

Computes the lifted structured loss.

@tf.function
tfa.losses.lifted_struct_loss(
    labels: tfa.types.TensorLike,
    embeddings: tfa.types.TensorLike,
    margin: tfa.types.FloatTensorLike = 1.0
) -> tf.Tensor

Args
`labels`	1-D tf.int32 `Tensor` with shape `[batch_size]` of multiclass integer labels.
`embeddings`	2-D float `Tensor` of embedding vectors. Embeddings should not be l2 normalized.
`margin`	Float, margin term in the loss definition.

Returns
`lifted_loss`	float scalar with dtype of embeddings.
