is a random combination of all the inputs; but which in test time
will be just the last input.
All but the last input will have a linear transform before we
randomly combine them; these linear transforms will be initialized
to the identity transform.
The idea is that the list of Tensors will be a list of outputs of multiple
conformer layers. This has a similar effect as iterated loss. (See:
