Prerequisites

Linux or OSX

NVIDIA GPU + CUDA (may CuDNN) and corresponding PyTorch framework (version 0.3.1)

Python 2.7/3.5

Datasets

We use NWPU-RESISC45 and UC Merced Land dataset in our experiments. For our mession, "data/NWPU-RESISC45/NWPU-45.txt" is the source list file and "/data/UCMercedLand-share/UCMerced-19.txt" is the target list file.

Training and Evaluation

First, you can manually download the PyTorch pre-trained model introduced in `torchvision' library or if you have connected to the Internet, you can automatically downloaded them. Then, you can train the model for each dataset using the followling command.

cd src
python train_pada.py --gpu_id 2 --net ResNet50 --dset NWPU-RESISC45 --s_dset_path ../data/NWPU-RESISC45/NWPU-45.txt --t_dset_path ../data/UCMercedLand-share/UCMerced-19.txt --test_interval 500 --snapshot_interval 5000 --output_dir san1

You can set the command parameters to switch between different experiments.

• "gpu_id" is the GPU ID to run experiments.
• "dset" parameter is the dataset selection. In our experiments, it is NWPU-RESISC45
• "s_dset_path" is the source dataset list.
• "t_dset_path" is the target dataset list.
• "test_interval" is the interval of iterations between two test phase.
• "snapshot_interval" is the interval of iterations between two snapshot models.
• "output_dir" is the output directory of the log and snapshot.
• "net" sets the base network. For details of setting, you can see network.py.
  • For AlexNet, "net" is AlexNet.
  • For VGG, "net" is like VGG16. Detail names are in network.py.
  • For ResNet, "net" is like ResNet50. Detail names are in network.py.
