tf.contrib.seq2seq.ScheduledOutputTrainingHelper

class tf.contrib.seq2seq.ScheduledOutputTrainingHelper

Defined in tensorflow/contrib/seq2seq/python/ops/helper.py.

See the guide: Seq2seq Library (contrib) > Dynamic Decoding

A training helper that adds scheduled sampling directly to outputs.

Returns False for sample_ids where no sampling took place; True elsewhere.

Properties

batch_size

Methods

__init__

__init__(
    inputs,
    sequence_length,
    sampling_probability,
    time_major=False,
    seed=None,
    next_input_layer=None,
    auxiliary_inputs=None,
    name=None
)

Initializer.

Args:

• inputs: A (structure) of input tensors.
• sequence_length: An int32 vector tensor.
• sampling_probability: A 0D float32 tensor: the probability of sampling from the outputs instead of reading directly from the inputs.
• time_major: Python bool. Whether the tensors in inputs are time major. If False (default), they are assumed to be batch major.
• seed: The sampling seed.
• next_input_layer: (Optional) An instance of tf.layers.Layer, i.e., tf.layers.Dense. Optional layer to apply to the RNN output to create the next input.
• auxiliary_inputs: An optional (structure of) auxiliary input tensors with a shape that matches inputs in all but (potentially) the final dimension. These tensors will be concatenated to the sampled output or the inputs when not sampling for use as the next input.
• name: Name scope for any created operations.

Raises:

• ValueError: if sampling_probability is not a scalar or vector.
