Descriptor for a layer normalization backward propagation primitive.

Construction¶

desc(
    prop_kind aprop_kind,
    const memory::desc& diff_data_desc,
    const memory::desc& data_desc,
    const memory::desc& stat_desc,
    float epsilon,
    normalization_flags flags
    )

Constructs a descriptor for layer normalization backward propagation primitive.

Parameters:

aprop_kind	Propagation kind. Possible values are dnnl::prop_kind::backward_data and dnnl::prop_kind::backward (diffs for all parameters are computed in this case).
diff_data_desc	Diff source and diff destination memory descriptor.
data_desc	Source memory descriptor.
stat_desc	Statistics memory descriptors.
epsilon	Layer normalization epsilon parameter.
flags	Layer normalization flags (dnnl::normalization_flags).

desc(
    prop_kind aprop_kind,
    const memory::desc& diff_data_desc,
    const memory::desc& data_desc,
    float epsilon,
    normalization_flags flags
    )
