Performs backpropagation of the binary logic loss function. reduction specifies the compute method of the loss function. It can be set to none, mean, or sum. none indicates that no reduction will be applied; mean indicates that the sum of the output will be divided by the number of elements in the output; sum indicates that the output will be summed.

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