Typedef Documentation

dnnl_logsoftmax_desc_t

typedef dnnl_softmax_desc_t dnnl_logsoftmax_desc_t

A descriptor of a LogSoftmax operation.

An alias of Softmax structure, but primitive_kind must be dnnl_logsoftmax.

Function Documentation

dnnl_logsoftmax_forward_desc_init()

dnnl_status_t DNNL_API dnnl_logsoftmax_forward_desc_init	(	dnnl_logsoftmax_desc_t *	logsoftmax_desc,
		dnnl_prop_kind_t	prop_kind,
		const dnnl_memory_desc_t *	data_desc,
		int	logsoftmax_axis
	)

Initializes a descriptor for logsoftmax forward propagation primitive.

Parameters

logsoftmax_desc	Output descriptor for a logsoftmax primitive.
prop_kind	Propagation kind. Possible values are dnnl_forward_training and dnnl_forward_inference.
data_desc	Source and destination memory descriptor.
logsoftmax_axis	Axis over which logsoftmax is computed.

Returns

dnnl_success on success and a status describing the error otherwise.

dnnl_logsoftmax_backward_desc_init()

dnnl_status_t DNNL_API dnnl_logsoftmax_backward_desc_init	(	dnnl_logsoftmax_desc_t *	logsoftmax_desc,
		const dnnl_memory_desc_t *	diff_data_desc,
		const dnnl_memory_desc_t *	data_desc,
		int	logsoftmax_axis
	)

Initializes a descriptor for logsoftmax backward propagation primitive.

Parameters

logsoftmax_desc	Output descriptor for a logsoftmax primitive.
diff_data_desc	Diff source and diff destination memory descriptors.
data_desc	Destination memory descriptor.
logsoftmax_axis	Axis over which softmax is computed.

Returns

dnnl_success on success and a status describing the error otherwise.
