Detailed Description

Descriptor for a deconvolution backward propagation primitive.

Constructor & Destructor Documentation

desc() [1/2]

dnnl::deconvolution_backward_data::desc::desc ( algorithm  algorithm, const memory::desc &  diff_src_desc, const memory::desc &  weights_desc, const memory::desc &  diff_dst_desc, const memory::dims &  strides, const memory::dims &  padding_l, const memory::dims &  padding_r  )

inline

Constructs a descriptor for a deconvolution backward propagation primitive.

Note

Memory descriptors can be initialized with dnnl::memory::format_tag::any value of format_tag.

Inputs:

• diff_dst (dnnl::primitive_desc_base::diff_dst_desc (0))
• weights (dnnl::primitive_desc_base::weights_desc (0))

Outputs:

• diff_src (dnnl::primitive_desc_base::diff_src_desc (0))

Parameters

algorithm	Deconvolution algorithm (dnnl::algorithm::convolution_direct, dnnl::algorithm::convolution_winograd).
diff_src_desc	Diff source memory descriptor.
weights_desc	Weights memory descriptor.
diff_dst_desc	Diff destination memory descriptor.
strides	Strides for each spatial dimension.
padding_l	Vector of padding values for low indices for each spatial dimension (front, top, left).
padding_r	Vector of padding values for high indices for each spatial dimension (back, bottom, right).

desc() [2/2]

dnnl::deconvolution_backward_data::desc::desc ( algorithm  algorithm, const memory::desc &  diff_src_desc, const memory::desc &  weights_desc, const memory::desc &  diff_dst_desc, const memory::dims &  strides, const memory::dims &  dilates, const memory::dims &  padding_l, const memory::dims &  padding_r  )

inline

Constructs a descriptor for a dilated deconvolution backward propagation primitive.

Note

Memory descriptors can be initialized with dnnl::memory::format_tag::any value of format_tag.

Inputs:

• diff_dst (dnnl::primitive_desc_base::diff_dst_desc (0))
• weights (dnnl::primitive_desc_base::weights_desc (0))

Outputs:

• diff_src (dnnl::primitive_desc_base::diff_src_desc (0))

Parameters

algorithm	Deconvolution algorithm (dnnl::algorithm::convolution_direct, dnnl::algorithm::convolution_winograd).
diff_src_desc	Diff source memory descriptor.
weights_desc	Weights memory descriptor.
diff_dst_desc	Diff destination memory descriptor.
strides	Strides for each spatial dimension.
dilates	Dilations for each spatial dimension. A zero value means no dilation in the corresponding dimension.
padding_l	Vector of padding values for low indices for each spatial dimension (front, top, left).
padding_r	Vector of padding values for high indices for each spatial dimension (back, bottom, right).
