Detailed Documentation

Descriptor for an inner product weights gradient primitive.
Construction
desc( const memory::desc& src_desc, const memory::desc& diff_weights_desc, const memory::desc& diff_bias_desc, const memory::desc& diff_dst_desc )
Constructs a descriptor for an inner product descriptor weights update primitive with bias.
All the memory descriptors may be initialized with the dnnl::memory::format_tag::any value of
format_tag
.
Parameters:
src_desc
Memory descriptor for src.
diff_weights_desc
Memory descriptor for diff weights.
diff_bias_desc
Memory descriptor for diff bias.
diff_dst_desc
Memory descriptor for diff dst.
desc( const memory::desc& src_desc, const memory::desc& diff_weights_desc, const memory::desc& diff_dst_desc )
Constructs a descriptor for an inner product descriptor weights update primitive without bias.
All the memory descriptors may be initialized with the dnnl::memory::format_tag::any value of
format_tag
.
Parameters:
src_desc
Memory descriptor for src.
diff_weights_desc
Memory descriptor for diff weights.
diff_dst_desc
Memory descriptor for diff dst.
