Hi
Sorry for late, I hope you've already figured it out.
The GAP baseline is as follows:
def gap_baseline(self, spt, qry):
spt = spt.squeeze(0)
# shifting channel activations by the channel mean
spt = self.normalize_feature(spt)
qry = self.normalize_feature(qry)
if self.args.shot > 1:
spt = spt.view(self.args.shot, self.args.way, *spt.shape[1:])
spt = spt.mean(dim=0)
spt = spt.unsqueeze(0).repeat(qry.shape[0], 1, 1)
qry_pooled = qry.mean(dim=[-1, -2])
# cosine similarity (l2 normalization involved)
similarity_matrix = F.cosine_similarity(spt, qry.unsqueeze(1), dim=-1)
if self.training:
return similarity_matrix / self.args.temperature, self.fc(qry_pooled)
else:
return similarity_matrix / self.args.temperature
I hope it works. Have a good weekend! 🙂
Best, Dahyun.
