.
Wasserstein discriminator loss for GANs.
See Wasserstein GAN
(https://arxiv.org/abs/1701.07875) for more details.
Args:
discriminator_real_outputs
: Discriminator output on real data.discriminator_gen_outputs
: Discriminator output on generated data. Expected to be in the range of (-inf, inf).real_weights
: OptionalTensor
whose rank is either 0, or the same rank asdiscriminator_real_outputs
, and must be broadcastable todiscriminator_real_outputs
(i.e., all dimensions must be either1
, or the same as the corresponding dimension).generated_weights
: Same asreal_weights
, but fordiscriminator_gen_outputs
.scope
: The scope for the operations performed in computing the loss.loss_collection
: collection to which this loss will be added.reduction
: Atf.losses.Reduction
to apply to loss.add_summaries
: Whether or not to add summaries for the loss.
Returns:
A loss Tensor. The shape depends on reduction
.
