### Sample Usage
This dataset contains the preprocessed data that can be used with the associated code from the [Learning-with-FrameProjections GitHub repository](https://github.com/eth-siplab/Learning-with-FrameProjections). Here are the quickstart commands for pre-training and testing:
**Pre-training + testing (our method)**
```bash
python main.py \
--framework isoalign \
--backbone resnet \
--dataset ieee_small \
--n_epoch 256 \
--batch_size 1024 \
--lr 1e-3 \
--lr_cls 0.03 \
--cuda 0 \
--cases subject_large
```
**Supervised baseline**
```bash
python main_supervised_baseline.py \
--dataset ieee_small \
--backbone resnet \
--block 8 \
--lr 5e-4 \
--n_epoch 999 \
--cuda 0
