Constructor & Destructor Documentation

desc()

dnnl::lrn_forward::desc::desc ( prop_kind prop_kind, algorithm algorithm, const memory::desc & data_desc, memory::dim local_size, float alpha, float beta, float k = 1.f )

inline

Constructs a descriptor for a LRN forward propagation primitive.

Inputs:

• src (dnnl::primitive_desc_base::src_desc(0))

Outputs:

• dst (dnnl::primitive_desc_base::dst_desc(0))
• workspace (dnnl::primitive_desc_base::workspace_desc(0)), if alg_kind = dnnl::algorithm::pooling_max and prop_kind = dnnl::prop_kind::forward_training; must be queried for using dnnl::primitive_desc_base::query_md() after a corresponding primitive descriptor is created

Parameters

prop_kind	Propagation kind. Possible values are dnnl::prop_kind::forward_training, and dnnl::prop_kind::forward_inference.
algorithm	LRN algorithm kind: either dnnl::algorithm::lrn_across_channels, or dnnl::algorithm::lrn_within_channel.
data_desc	Source and destination memory descriptors.
local_size	Regularization local size.
alpha	The alpha regularization parameter.
beta	The beta regularization parameter.
k	The k regularization parameter.
