    algorithm aalgorithm,
    const memory::desc& data_desc,
    memory::dim local_size,
    float alpha,
    float beta,

Constructs a descriptor for a LRN forward propagation primitive.

Parameters:

aprop_kind	Propagation kind. Possible values are dnnl::prop_kind::forward_training, and dnnl::prop_kind::forward_inference.
aalgorithm	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.
