Detailed Documentation

Descriptor for a softmax backward propagation primitive.
Construction
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
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.
