Detailed Documentation

Descriptor for a softmax backward propagation primitive.

Methods

desc()

Default constructor. Produces an empty object.

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

Constructs a descriptor for a softmax backward propagation primitive.

Parameters:

aalgorithm

Softmax algorithm kind: either dnnl::algorithm::softmax_accurate, or dnnl::algorithm::softmax_log.

diff_src_desc

Diff source memory descriptor.

diff_dst_desc

Diff destination memory descriptor.

dst_desc

Destination memory descriptor.

softmax_axis

Axis over which softmax is computed.
