Methods

backward(node, *args, **kwargs)	Propagate the feedback backward.
default_propagator()	Return the default Propagator object of the optimizer.
propose(*args, **kwargs)	Propose the new data of the parameters based on the feedback.
step(*args, **kwargs)	Update the parameters based on the feedback.
update(update_dict)	Update the trainable parameters given a dictionary of new data.
zero_feedback()	Reset the feedback.
