/**
* @brief Calculates the reversed outputs of the function "embedding". \n

* @par Inputs:
* Four inputs, including:
* @li weight: A mutable Tensor of word grad. Must be one of the following types:
*     float32.
* @li indices: A mutable word index Tensor of the int32 type.\n
* @li offsets: A mutable word index Tensor of the int32 type.\n
* @li per_sample_weights: to indicate all weights should be taken to be 1.
*     If specified, per_sample_weights must have exactly the same shape as input
*     and is treated as having the same offsets, if those are not None.
*     Only supported for mode='sum'..\n

* @par Attributes:
* @li mode: An string attr which use "sum"``, ``"mean"`` or ``"max"``. Specifies the way to reduce the bag.. \n

* @li scale_grad_by_freq: An optional bool. Defaults to "False".
*     If "True", "grad_weight" will be scale by word_frequency.
*     If "False", "grad_weight" will not be scale by word_frequency. \n
* @li sparse: if True, gradient w.r.t.attr weight matrix will be a sparse tensor. \n
* @li include_last_offset: if True, attr offsets  has one additional element, where the last element
*     is equivalent to the size of indices. This matches the CSR format.. \n

* @par Outputs:
* @li grad_weight: A mutable output Tensor of new word grad has the same type as "grads". \n

* @par Third-party framework compatibility
* Compatible with the Pytorch operator EmbeddingBag.
