title: Assuming the order Conv2d->ReLU->BN, should the Conv2d layer have a bias parameter?
body: <p>Should we include the bias parameter in <code>Conv2d</code> if we are going for <code>Conv2d</code> followed by <code>ReLU</code> followed by <code>batch norm (bn)</code>? </p>
  
  <p>There is no need if we go for <code>Conv2d</code> followed by <code>bn</code> followed by <code>ReLU</code>, since the shift parameter of <code>bn</code> takes care of bias work.</p>
