Detailed Documentation

Descriptor for a softmax backward propagation primitive.

Methods

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.
