Detailed Description

Descriptor for an inner product weights gradient primitive.

Constructor & Destructor Documentation

desc() [1/2]

dnnl::inner_product_backward_weights::desc::desc ( const memory::desc &  src_desc, const memory::desc &  diff_weights_desc, const memory::desc &  diff_bias_desc, const memory::desc &  diff_dst_desc  )

inline

Constructs a descriptor for an inner product descriptor weights update primitive with bias.

Inputs:

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

Outputs:

• diff_weights (dnnl::primitive_desc_base::diff_weights_desc(0))
• diff_bias (dnnl::primitive_desc_base::diff_weights_desc(1))

Note

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() [2/2]

dnnl::inner_product_backward_weights::desc::desc ( const memory::desc &  src_desc, const memory::desc &  diff_weights_desc, const memory::desc &  diff_dst_desc  )

inline

Constructs a descriptor for an inner product descriptor weights update primitive without bias.

Inputs:

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

Outputs:

• diff_weights (dnnl::primitive_desc_base::diff_weights_desc(0))

Note

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.
