[object Object][object Object][object Object]undefined[object Object]

• Description: Performs backward propagation of the aclnnNsaCompress operator.

• Formulas: The forward propagation formulas for selected attention are as follows:

  $$\text{dw} = \text{dk\_cmp} \cdot K^\top$$ $$\text{dk} = W^\top \cdot \text{dk\_cmp}$$

[object Object]

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

• Deterministic computation:
  • [object Object] defaults to a deterministic implementation.
• [object Object] and [object Object] must be integer multiples of 16 and [object Object] must be greater than [object Object].
