Global Functions

dnnl_status_t DNNL_API dnnl_inner_product_forward_desc_init(
    dnnl_inner_product_desc_t* ip_desc,
    dnnl_prop_kind_t prop_kind,
    const dnnl_memory_desc_t* src_desc,
    const dnnl_memory_desc_t* weights_desc,
    const dnnl_memory_desc_t* bias_desc,
    const dnnl_memory_desc_t* dst_desc
    )

Initializes descriptor for inner product forward propagation.

Note

Memory descriptors can be initialized with dnnl_format_tag_any or with format_kind set to dnnl_format_kind_any.

Parameters:

ip_desc	Output descriptor for inner product primitive.
prop_kind	Propagation kind. Possible values are dnnl_forward_training and dnnl_forward_inference.
src_desc	Source memory descriptor.
weights_desc	Weights memory descriptor.
bias_desc	Bias memory descriptor. Passing NULL, a zero memory descriptor, or a memory descriptor with format_kind set to dnnl_format_kind_undef disables the bias term.
dst_desc	Destination memory descriptor.

Returns:

dnnl_success on success and a status describing the error otherwise.

dnnl_status_t DNNL_API dnnl_inner_product_backward_data_desc_init(
    dnnl_inner_product_desc_t* ip_desc,
    const dnnl_memory_desc_t* diff_src_desc,
    const dnnl_memory_desc_t* weights_desc,
    const dnnl_memory_desc_t* diff_dst_desc
    )

Initializes descriptor for inner product backward propagation.

Note

Memory descriptors can be initialized with dnnl_format_tag_any or with format_kind set to dnnl_format_kind_any.

Parameters:

ip_desc	Output descriptor for inner product primitive.
diff_src_desc	Diff source memory descriptor.
weights_desc	Weights memory descriptor.
diff_dst_desc	Diff destination memory descriptor.

Returns:

dnnl_success on success and a status describing the error otherwise.

dnnl_status_t DNNL_API dnnl_inner_product_backward_weights_desc_init(
    dnnl_inner_product_desc_t* ip_desc,
    const dnnl_memory_desc_t* src_desc,
    const dnnl_memory_desc_t* diff_weights_desc,
    const dnnl_memory_desc_t* diff_bias_desc,
    const dnnl_memory_desc_t* diff_dst_desc
    )

Initializes descriptor for inner product weights gradient primitive.

Note

Memory descriptors can be initialized with dnnl_format_tag_any or with format_kind set to dnnl_format_kind_any.

Parameters:

ip_desc	Output descriptor for inner product primitive.
src_desc	Source memory descriptor.
diff_weights_desc	Diff weights memory descriptor.
diff_bias_desc	Diff bias memory descriptor. Passing NULL, a zero memory descriptor, or a memory descriptor with format_kind set to dnnl_format_kind_undef disables the bias term.
diff_dst_desc	Diff destination memory descriptor.

Returns:

dnnl_success on success and a status describing the error otherwise.
