description: <<END
Specify the data format of the input and output data. With the
default format "NHWC", the bias tensor will be added to the last dimension
of the value tensor.
Alternatively, the format could be "NCHW", the data storage order of:
[batch, in_channels, in_height, in_width].
The tensor will be added to "in_channels", the third-to-the-last
dimension.
END
}
summary: "The backward operation for \"BiasAdd\" on the \"bias\" tensor."
description: <<END
It accumulates all the values from out_backprop into the feature dimension.
For NHWC data format, the feature dimension is the last. For NCHW data format,
the feature dimension is the third-to-last.
END
