Detailed Documentation

Descriptor for a softmax backward propagation primitive.
Construction
desc()
Default constructor. Produces an empty object.
desc(
    const memory::desc& diff_data_desc,
    const memory::desc& data_desc,
    int softmax_axis
    )
Constructs a descriptor for a softmax backward propagation primitive.
Parameters:
diff_data_desc
Diff source and diff destination memory descriptor.
data_desc
Destination memory descriptor.
softmax_axis
Axis over which softmax is computed.
