Detailed Documentation

Descriptor for an elementwise backward propagation primitive.
Construction
desc( algorithm aalgorithm, const memory::desc& diff_data_desc, const memory::desc& data_desc, float alpha = 0, float beta = 0 )
Constructs a descriptor for an elementwise backward propagation primitive.
Parameters:
aalgorithm
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.
