self.use_feat_bank's impact on the results

WillYao-THU opened this issue · comments

Hi！I have a few questions:

  1. How can we decide whether self.use_feat_bank should be False or True, and what impact does this have on the results? I found the results worsened after setting self.use_feat_bank to True.
  2. Why can't self.appearance_dim be equal to zero when self.use_feat_bank is set to true?

Looking forward to your reply, thanks!

Hi, the feat bank works well when you have many views from different directions and distance to train the MLP fully. We set it to False by default because most of the public scenes does not contain sufficient view changes. And, the second question is an implementation issue, feel free to modify or improve it as you like.
