• Description: Performs backpropagation of aclnnMoeFinalizeRoutingV2.
• Formulas:$$i : 0 \sim R * K - 1$$ $$j : 0 \sim H$$ (1) [object Object] is a null pointer:$$gradExpandedXOut[expandedRowIdx[i]][j] = gradY[i / K][j]$$ (2) [object Object] is not a null pointer, and [object Object] is a null pointer:$$gradExpandedXOut[expandedRowIdx[i]][j] = gradY[i / K][j] * scalesOptional[i / K][i \% K]$$ $$gradScalesOut[i] = sum(expandedXOptional[expandedRowIdx[i]][j] * gradY[i / K][j])$$ (3) [object Object] and [object Object] are not null pointers:$$gradExpandedXOut[expandedRowIdx[i]][j] = gradY[i / K][j] * scalesOptional[i / K][i \% K]$$ $$gradScalesOut[i] = sum((expandedXOptional[expandedRowIdx[i]][j] + biasOptional[expertIdxOptional[i]][j]) * gradY[i / K][j])$$ R indicates batch x sequence, H indicates hidden, and K indicates topK.

Each operator consists of . You must first call the [object Object] API to obtain the required workspace size and the executor that contains the operator computation flow, and then call the [object Object] API to execute the computation.
