BiasAdd {#dev_guide_op_biasadd}

General

Add bias to channel dimension of input. This is a special Add with bias restricted to be 1-D. Broadcasting is supported.

\f[ \dst(n,c,h,w) = \src(n,c,h,w) + \bias(c) \f]

Attribute Name	Description	Value Type	Supported Values	Required or Optional
[data_format](@ref dnnl::graph::op::attr::data_format)	Controls how to interpret the shape of `src` and `dst`.	string	`NCX` , `NXC` (default)	Optional

The inputs and outputs must be provided according to below index order when constructing an operation.

Index	Argument Name	Required or Optional
0	`src`	Required
1	`bias`	Required

@note bias is a 1D tensor to be added to src tensor. The size should be the same as size of channel dimension of src tensor.

Index	Argument Name	Required or Optional
0	`dst`	Required

BiasAdd operation supports the following data type combinations.
