Detailed Description

Typedef Documentation

typedef dnnl_convolution_desc_t dnnl_deconvolution_desc_t

A descriptor of a deconvolution operation.

Function Documentation

dnnl_status_t DNNL_API dnnl_deconvolution_backward_data_desc_init	(	dnnl_deconvolution_desc_t *	deconv_desc,
		dnnl_alg_kind_t	alg_kind,
		const dnnl_memory_desc_t *	diff_src_desc,
		const dnnl_memory_desc_t *	weights_desc,
		const dnnl_memory_desc_t *	diff_dst_desc,
		const dnnl_dims_t	strides,
		const dnnl_dims_t	padding_l,
		const dnnl_dims_t	padding_r
	)

Initializes a descriptor for a deconvolution backward propagation primitive.

Note

Memory descriptors can be initialized with dnnl_format_tag_any or with format_kind set to dnnl_format_kind_any.

Arrays strides, padding_l, and padding_r contain values for spatial dimensions only and hence must have the same number of elements as there are spatial dimensions. The order of values is the same as in the tensor: depth (for 3D tensors), height (for 3D and 2D tensors), and width.

Parameters

deconv_desc	Output descriptor for a deconvolution primitive.
alg_kind	Deconvolution algorithm. Possible values are dnnl_deconvolution_direct, dnnl_deconvolution_winograd.
diff_src_desc	Diff source memory descriptor.
weights_desc	Weights memory descriptor.
diff_dst_desc	Diff destination memory descriptor.
strides	Array of strides for spatial dimension.
padding_l	Array of padding values for low indices for each spatial dimension ([[front,] top,] left).
padding_r	Array of padding values for high indices for each spatial dimension ([[back,] bottom,] right). Can be NULL in which case padding is considered to be symmetrical.

Returns

dnnl_success on success and a status describing the error otherwise.

		const dnnl_dims_t	strides,
		const dnnl_dims_t	padding_l,
		const dnnl_dims_t	padding_r
	)

Initializes a descriptor for a deconvolution weights gradient primitive.

Note

Memory descriptors can be initialized with dnnl_format_tag_any or with format_kind set to dnnl_format_kind_any.

Arrays strides, padding_l, and padding_r contain values for spatial dimensions only and hence must have the same number of elements as there are spatial dimensions. The order of values is the same as in the tensor: depth (for 3D tensors), height (for 3D and 2D tensors), and width.

Parameters

deconv_desc	Output descriptor for a deconvolution primitive.
alg_kind	Deconvolution algorithm. Possible values are dnnl_deconvolution_direct, dnnl_deconvolution_winograd.
src_desc	Source memory descriptor.
diff_weights_desc	Diff weights memory descriptor.
diff_bias_desc	Diff bias memory descriptor. Passing NULL, a zero memory descriptor, or a memory descriptor with format_kind set to dnnl_format_kind_undef disables the bias term.
diff_dst_desc	Diff destination memory descriptor.
strides	Array of strides for spatial dimension.
padding_l	Array of padding values for low indices for each spatial dimension ([[front,] top,] left).
padding_r	Array of padding values for high indices for each spatial dimension ([[back,] bottom,] right). Can be NULL in which case padding is considered to be symmetrical.

Returns

dnnl_success on success and a status describing the error otherwise.

Note
