[object Object]

• Description: Normalizes a batch of data. The statistical result of the generated data after normalization is 0 (mean value) or 1 (standard deviation).

• Formula:

  $$y = \frac{(x - E(x))}{\sqrt{Var(x) + eps}} * weight + bias$$

  E(x) indicates the mean value and Var(x) indicates the variance, which need to be computed in the operator. ε indicates an extremely small floating point number to prevent the denominator from being 0.

Each operator has calls. First, aclnnBatchNormGetWorkspaceSize is called to obtain the input parameters and compute the required workspace size based on the process. Then, aclnnBatchNorm is called to perform computation.

• Parameters

  [object Object]
  • [object Object]Atlas training products[object Object] and [object Object]Atlas inference products[object Object]:
    • The data types of the [object Object], [object Object], [object Object], [object Object], [object Object], [object Object], [object Object], and [object Object] parameters cannot be BFLOAT16.
    • The data formats of the [object Object] and [object Object] parameters cannot be NHWC or NDHWC.
    • The [object Object] parameter indicates the variance of the input.
  • [object Object]Atlas A2 training products/Atlas A2 inference products[object Object] and [object Object]Atlas A3 training products/Atlas A3 inference products[object Object]:
    • The data formats of the <idp:inline displayname="code" id="code15528103664517">input[object Object] and <idp:inline displayname="code" id="code11528183617451">output[object Object] parameters cannot be NHWC or NDHWC.
    • The [object Object] parameter indicates the variance of the input.
  • Ascend 950PR/Ascend 950DT: The [object Object] parameter indicates the reciprocal of the standard deviation of the input.

• Returns:

• Deterministic compute:
  • aclnnBatchNorm defaults to a non-deterministic implementation. You can call aclrtCtxSetSysParamOpt to enable deterministic compute.
