| dnnl_prop_kind_t dnnl_eltwise_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_eltwise_desc_t::alg_kind |
The kind of eltwise algorithm.
Possible values: dnnl_eltwise_relu, dnnl_eltwise_tanh, dnnl_eltwise_elu, dnnl_eltwise_square, dnnl_eltwise_abs, dnnl_eltwise_sqrt, dnnl_eltwise_linear, dnnl_eltwise_bounded_relu, dnnl_eltwise_soft_relu, dnnl_eltwise_logistic, dnnl_eltwise_exp, dnnl_eltwise_gelu, dnnl_eltwise_swish, dnnl_eltwise_log, dnnl_eltwise_clip.
