bias in projection

[hlr7999]

Hi, i have a question about the bias in projection (feature adapter in paper). The description in the paper is

The later feature adaptor is essentially a fully connected layer without bias

However, the code in Projection is

self.layers.add_module(f"{i}fc", 
                                   torch.nn.Linear(_in, _out))

Since the default argument of bias is True in torch.nn.Linear, It this a mistake or the existence of bias is not important ?

In my experiments, it can be as simple as without bias, or the bias is not that important.
