A time series head which exports a single stateless serving signature.
The serving default signature exported by this head expects

When serving, first performs filtering on the series up to
starting from the default start state for the model, then computes predictions
on the remainder of the series, returning them.
Model state is neither accepted nor returned, so filtering must be performed each time predictions are requested when using this head.
__init__( model, state_manager, optimizer, input_statistics_generator=None, name=None )
_Head for time series regression.
model: A model for time series regression.
state_manager: A state manager.
optimizer: An optimizer.
input_statistics_generator: A input statistics generator.
name: An optional name for the model.
create_estimator_spec( features, mode, labels=None )
Performs basic error checking and returns an EstimatorSpec.
