Attentional Feature Fusion
MXNet/Gluon code for "Attentional Feature Fusion" https://arxiv.org/abs/2009.14082
What's in this repo so far:
- Code, trained models, and training logs for ImageNet
PS:
- If you are the reviewers of our submitted paper, please note that the accuracy of current implementation is a bit higher than the accuracy in the paper because it is a new implementation with a bag of tricks.
- 如果您是我的学位论文评审专家,发现论文与这个 repo 的数字有些出入,那是因为在论文提交后我又将代码重新实现了一遍,添加了 AutoAugment、Label Smooting 这些技巧,所以目前这个 repo 中的分类准确率会比论文中的数字高一些,还请见谅。
Change Logs:
- 2020-10-08: Re-implement the image classification code with a bag of tricks
- 2020-09-29: Upload the image classification codes and trained models for the submitted paper
To Do:
- Running AFF-ResNeXt-50 and AFF-ResNet-50 on ImageNet
