Detailed Documentation

A descriptor of a Softmax operation.

Fields

dnnl_primitive_kind_t primitive_kind

The kind of primitive.

Used for self-identifying the primitive descriptor. Must be dnnl_softmax_v2.

dnnl_prop_kind_t prop_kind

The kind of propagation.

Possible values: dnnl_forward_training, dnnl_forward_inference, and dnnl_backward_data.

dnnl_memory_desc_t src_desc

Source memory descriptor.

dnnl_memory_desc_t diff_src_desc

Source gradient memory descriptor.

int softmax_axis

The axis along which to perform the softmax.

dnnl_alg_kind_t alg_kind

Softmax algorithm.

Possible values: dnnl_softmax_accurate and dnnl_softmax_log.

dnnl_memory_desc_t dst_desc

Destination memory descriptor.

dnnl_memory_desc_t diff_dst_desc

Destination gradient memory descriptor.
