Channel-wise Position Encoding

1. Train and Test GAPNet for location classification or image recognition using the following commands:

        cd channel-wise-position-encoding/
        python trainval_gapnet.py 
        python test_gapnet.py 
        
   

2. Train and Test PermuteNet for location classification or image recognition using the following commands:

        cd channel-wise-position-encoding/
        python trainval_permutenet.py 
        python test_permutenet.py 
   

Learning Translation Invariant Representation

Code coming soon!

Targeting Position-Encoding Channels

Identify and Rank the position encoding channels followed by targeting the ranked channels using the following commands:

        cd position_attack/
        bash run_rank_target_neurons.sh

Please download the DeepLabv3-ResNet50 model trained on Cityscapes from Dropbox and put it under ./position_attack/checkpoints/

Download the cityscapes dataset and change the dataset root path accordingly!
