Detailed Description

A primitive to perform softmax.

where are outer and inner sizes repectively, defined by data_desc.dims and softmax_axis.

Function Documentation

mkldnn_status_t MKLDNN_API mkldnn_softmax_backward_desc_init	(	mkldnn_softmax_desc_t *	softmax_desc,
		const mkldnn_memory_desc_t *	diff_desc,
		const mkldnn_memory_desc_t *	data_desc,
		int	softmax_axis
	)

Initializes a softmax_desc for backward propagation using memory descriptors diff_desc and data_desc.

Order of inputs:

• dst (mkldnn_query_dst_pd, 0)
• diff_dst (mkldnn_query_diff_dst_pd, 0)

Order of outputs:

• diff_src (mkldnn_query_diff_src_pd, 0)

mkldnn_status_t MKLDNN_API mkldnn_softmax_forward_desc_init	(	mkldnn_softmax_desc_t *	softmax_desc,
		mkldnn_prop_kind_t	prop_kind,
		const mkldnn_memory_desc_t *	data_desc,
		int	softmax_axis
	)

Initializes a softmax_desc for forward propagation using prop_kind (possible values are mkldnn_forward_training and mkldnn_forward_inference) and memory descriptor data_desc.

Order of inputs:

• src (mkldnn_query_src_pd, 0)

Order of outputs:

• dst (mkldnn_query_dst_pd, 0)
