• Description: Performs backpropagation of the MaxPool2d inverse operation (), writing element values of gradOutput in out based on indices.

• Formula:

  $$out[n][c][i] = gradOutput[n][c][indices[n][c][i]]$$

  out, gradOutput, and indices are obtained by reshaping the axis combined from the last two axes, that is, $i ∈ [0, H*W)$. H and W represent the last two axes.

Each operator has calls. First, aclnnMaxUnpool2dBackwardGetWorkspaceSize is called to obtain the workspace size required for computation and the executor that contains the operator computation process. Then, aclnnMaxUnpool2dBackward is called to perform computation.
