Descriptor for a resampling backward propagation primitive.

Methods

desc(
    algorithm aalgorithm,
    const memory::desc& diff_src_desc,
    const memory::desc& diff_dst_desc
    )

Constructs a descriptor for a resampling backward propagation primitive using source and destination memory descriptors.

Parameters:

aalgorithm

resampling algorithm kind: either dnnl::algorithm::resampling_nearest, or dnnl::algorithm::resampling_linear

diff_src_desc

Diff source memory descriptor.

diff_dst_desc

Diff destination memory descriptor.

desc(
    algorithm aalgorithm,
    const std::vector<float>& factors,
