Member Data Documentation

◆ primitive_kind

dnnl_primitive_kind_t dnnl_lrn_desc_t::primitive_kind

The kind of primitive.

Used for self-identifying the primitive descriptor. Must be dnnl_lrn.

◆ prop_kind

dnnl_prop_kind_t dnnl_lrn_desc_t::prop_kind

The kind of propagation.

Possible values: dnnl_forward_training, dnnl_forward_inference, dnnl_backward, and dnnl_backward_data.

◆ alg_kind

dnnl_alg_kind_t dnnl_lrn_desc_t::alg_kind

LRN algorithm.

Possible values: dnnl_lrn_within_channel and dnnl_lrn_across_channels.

◆ local_size

dnnl_dim_t dnnl_lrn_desc_t::local_size

The number of channels to sum over (for cross-channel LRN) or the side length of the square region to sum over (for within-channel LRN).
