Defined in tensorflow/contrib/gan/python/estimator/python/head_impl.py.

Creates a GANHead. (deprecated)

Args:

• generator_loss_fn: A TFGAN loss function for the generator. Takes a GANModel and returns a scalar.
• discriminator_loss_fn: Same as generator_loss_fn, but for the discriminator.
• generator_optimizer: The optimizer for generator updates.
• discriminator_optimizer: Same as generator_optimizer, but for the discriminator updates.
• use_loss_summaries: If True, add loss summaries. If False, does not. If None, uses defaults.
• get_hooks_fn: A function that takes a GANTrainOps tuple and returns a list of hooks.
• get_eval_metric_ops_fn: A function that takes a GANModel, and returns a dict of metric results keyed by name. The output of this function is passed into tf.estimator.EstimatorSpec during evaluation.
• name: name of the head. If provided, summary and metrics keys will be suffixed by "/" + name.

Returns:

An instance of GANHead.
