How to use

Dependencies

  1. torch 2.0.1
  2. torchvision 0.15.2
  3. timm 0.6.12 (Note, for reproducing ARC + DER, we recommend using timm 0.5.4)
  4. tqdm
  5. numpy
  6. scipy

Run experiment

  1. Edit the [MODEL NAME].json file for global settings and hyperparameters.

  2. Run:

    python main.py --config=./exps/[MODEL NAME].json

Implementation details

  1. We primarily modified the _eval_cnn function in the files within the models directory compared to the PILOT version.
  2. Compared to the original conference version, we have re-implemented the framework. In the previous version, the inference process was fixed to a batch size of 1. In the new implementation, we introduce the arc_batch_size hyperparameter, which allows the inference batch size to be adjusted. Empirically, we observe that increasing this parameter tends to reduce overall accuracy while improving inference speed.
  3. The current version achieves substantially faster inference while maintaining comparable, and in some cases better, performance compared to the original version.
