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.
