# HFLB (Heterogeneous Federated Learning Benchmark)

FL Benchmark originally proposed in [FedDAT](https://arxiv.org/abs/2308.12305), and modified by ourselves, splitting each dataset into different subtasks for task incremental learning setup in [FedMosaic (ICLR 2026)](https://openreview.net/forum?id=0g5Dk4Qfh0).
Please checkout configuration of HFLB in the [paper](https://openreview.net/forum?id=0g5Dk4Qfh0)

### Constituent Datasets
| Dataset | Task Type | Reference |
|---|---|---|
| GQA | Compositional visual reasoning | Hudson & Manning, CVPR 2019 |
| Abstract VQA | Abstract-scene visual question answering | Antol et al., ICCV 2015 |
| SNLI-VE | Visual entailment | Xie et al., arXiv 2019 |
| COCO-QA | Image question answering | Ren et al., NeurIPS 2015 |
| NLVR2 | Natural-language visual reasoning over image pairs | Suhr et al., ACL 2019 |
| VizWiz | Accessibility-focused VQA | Gurari et al., CVPR 2018 |
| NLVR2 | Dual-image visual reasoning | Suhr et al., ACL 2019 |
| AQUA | Art-domain visual question answering | Garcia et al., ECCV Workshops 2020 |

## How to Download

We highly recommend downloading each dataset (`.tar`) file separately:

```bash
# Example: Download GQA
huggingface-cli download SNUMPR/HFLB GQA.tar --local-dir ./ --repo-type dataset

# Example: Download AQUA
huggingface-cli download SNUMPR/HFLB AQUA.tar --local-dir ./ --repo-type dataset
```

After downloading, extract each archive:
```bash
tar -xvf AQUA.tar
# Repeat for other archives
```

Place extracted data under the `dataset/` folder in the [code repository](https://github.com/snumprlab/fedmosaic), following the structure described in the [README](https://github.com/snumprlab/fedmosaic/blob/main/README.md).
