ACGAN loss for the discriminator.

The ACGAN loss adds a classification loss to the conditional discriminator. Therefore, the discriminator must output a tuple consisting of (1) the real/fake prediction and (2) the logits for the classification (usually the last conv layer, flattened).

For more details: ACGAN: https://arxiv.org/abs/1610.09585

Args:

  • discriminator_real_classification_logits: Classification logits for real data.
  • discriminator_gen_classification_logits: Classification logits for generated data.
  • one_hot_labels: A Tensor holding one-hot labels for the batch.
  • label_smoothing: A float in [0, 1]. If greater than 0, smooth the labels for "discriminator on real data" as suggested in https://arxiv.org/pdf/1701.00160
  • real_weights: Optional Tensor whose rank is either 0, or the same rank as discriminator_real_outputs, and must be broadcastable to discriminator_real_outputs (i.e., all dimensions must be either 1, or the same as the corresponding dimension).
  • generated_weights: Same as real_weights, but for discriminator_gen_classification_logits.
  • scope: The scope for the operations performed in computing the loss.
  • loss_collection: collection to which this loss will be added.
  • reduction: A tf.losses.Reduction to apply to loss.
  • add_summaries: Whether or not to add summaries for the loss.

Returns:

A loss Tensor. Shape depends on reduction.

Raises:

  • TypeError: If the discriminator does not output a tuple.
