Detailed Description

Descriptor for an elementwise backward propagation primitive.

Examples:

cnn_training_f32.cpp, and cpu_cnn_training_bf16.cpp.

Constructor & Destructor Documentation

desc()

dnnl::eltwise_backward::desc::desc ( algorithm  algorithm, const memory::desc &  diff_data_desc, const memory::desc &  data_desc, float  alpha = 0, float  beta = 0  )

inline

Constructs a descriptor for an elementwise backward propagation primitive.

Inputs:

• src (dnnl::primitive_desc_base::src_desc(0))
• diff_dst (dnnl::primitive_desc_base::diff_dst_desc(0))

Outputs:

• diff_src (dnnl::primitive_desc_base::diff_src_desc(0))

Parameters

algorithm	Elementwise algorithm kind.
diff_data_desc	Diff source and destination memory descriptors.
data_desc	Source memory descriptor.
alpha	The alpha parameter for the elementwise operation. Specific meaning depends on the algorithm.
beta	The beta parameter for the elementwise operation. Specific meaning depends on the algorithm.
