• Description: Performs backpropagation of to compute the gradient gradInput of backpropagation.
• Formula:$$HardshrinkBackward(x,grad)= \begin{cases} &grad, &if(x > \lambda) \\ &grad, &if(x < -\lambda) \\ &0, &otherwise \end{cases}$$

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