• Description: Performs backpropagation of .

• Formula:

  $$\frac{\partial GLU(a,b)}{\partial(a,b)}=cat(\sigma(b),\sigma(b) \otimes a \otimes (1-\sigma(b)))$$

• Mathematical expression:

  Assume that the output GLUGrad consists of two parts: out = [a_grad, b_grad]. sig_b = sigmoid(b) a_grad=y_gradsig_b b_grad=a_grad(a-a*sig_b) y_grad indicates gradOut, a indicates the first tensor after the input tensor is evenly divided based on the specified dim, and b indicates the second tensor.

Each operator has calls. First, aclnnGluBackwardGetWorkspaceSize is called to obtain the workspace size required for computation and the executor that contains the operator computation process. Then, aclnnGluBackward is called to perform computation.
