Detailed Description

Descriptor for a pooling backward propagation primitive.

Constructor & Destructor Documentation

desc()

dnnl::pooling_v2_backward::desc::desc ( algorithm  aalgorithm, const memory::desc &  diff_src_desc, const memory::desc &  diff_dst_desc, const memory::dims &  strides, const memory::dims &  kernel, const memory::dims &  dilation, const memory::dims &  padding_l, const memory::dims &  padding_r  )

inline

Constructs a descriptor for pooling v2 (dilated pooling) backward propagation primitive.

Arrays strides, kernel, dilation, 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

aalgorithm	Pooling algorithm kind: either dnnl::algorithm::pooling_max, dnnl::algorithm::pooling_avg_include_padding, or dnnl::algorithm::pooling_avg (same as dnnl::algorithm::pooling_avg_exclude_padding).
diff_src_desc	Diff source memory descriptor.
diff_dst_desc	Diff destination memory descriptor.
strides	Vector of strides for spatial dimension.
kernel	Vector of kernel spatial dimensions.
dilation	Array of dilations for 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).
