Detailed Description

Function Documentation

dnnl_status_t DNNL_API dnnl_lrn_backward_desc_init	(	dnnl_lrn_desc_t *	lrn_desc,
		dnnl_alg_kind_t	alg_kind,
		const dnnl_memory_desc_t *	diff_data_desc,
		const dnnl_memory_desc_t *	data_desc,
		dnnl_dim_t	local_size,
		float	alpha,
		float	beta,
		float	k
	)

Initializes a descriptor for LRN backward propagation primitive.

Parameters

lrn_desc	Output descriptor for a LRN primitive.
alg_kind	LRN algorithm kind: either dnnl_lrn_across_channels or dnnl_lrn_within_channel.
diff_data_desc	Diff source and diff destination memory descriptor.
data_desc	Source memory descriptor.
local_size	Regularization local size.
alpha	The alpha regularization parameter.
beta	The beta regularization parameter.
k	The k regularization parameter.

Returns: dnnl_success on success and a status describing the error otherwise.
