Detailed Description

Descriptor for a layer normalization forward propagation primitive.

Constructor & Destructor Documentation

desc() [1/2]

dnnl::layer_normalization_forward::desc::desc ( prop_kind  prop_kind, const memory::desc &  data_desc, const memory::desc &  stat_desc, float  epsilon, normalization_flags  flags  )

inline

Constructs a descriptor for layer normalization forward propagation primitive.

Inputs:

• src (dnnl::primitive_desc_base::src_desc (0))
• mean (dnnl::primitive_desc_base::src_desc (1)), if dnnl::normalization_flags::use_global_stats bit-flag is set in flags
• variance (dnnl::primitive_desc_base::src_desc (2)), if dnnl::normalization_flags::use_global_stats bit-flag is set in flags
• scale_and_shift (dnnl::primitive_desc_base::weights_desc (0)), if dnnl::normalization_flags::use_scale_shift bit-flag is set in flags

Outputs:

• dst (dnnl::primitive_desc_base::dst_desc (0))
• mean (dnnl::primitive_desc_base::dst_desc (1)), if dnnl::normalization_flags::use_global_stats bit-flag is not set in flags and prop_kind = dnnl::prop_kind::forward_training
• variance (dnnl::primitive_desc_base::dst_desc (2)), if dnnl::normalization_flags::use_global_stats bit-flag is not set in flags and prop_kind = dnnl::prop_kind::forward_training

Parameters

prop_kind	Propagation kind. Possible values are dnnl::prop_kind::forward_training, and dnnl::prop_kind::forward_inference.
data_desc	Source and destination memory descriptor.
stat_desc	Statistics memory descriptors.
epsilon	Layer normalization epsilon parameter.
flags	Layer normalization flags (dnnl::normalization_flags).
