Dataset Card for Fed-ISIC-2019
Federated version of ISIC-2019 Datasets (ISIC2019 challenge and the HAM1000 database).The dataset contains 6 clients whose data comes from different data centers.
Dataset Details
The dataset contains 23,247 images of skin lesions. The number of samples for train/test per each data center is displayed in the table below.
| center_id | Train | Test |
|---|---|---|
| 0 | 9930 | 2483 |
| 1 | 3163 | 791 |
| 2 | 2691 | 672 |
| 3 | 1807 | 452 |
| 4 | 655 | 164 |
| 5 | 351 | 88 |

Use in FL
In order to prepare the dataset for the FL settings, we recommend using Flower Dataset (flwr-datasets) for the dataset download and partitioning and Flower (flwr) for conducting FL experiments.
To partition the dataset, do the following.
- Install the package.
pip install flwr-datasets[vision]
- Use the HF Dataset under the hood in Flower Datasets.
from flwr_datasets import FederatedDataset
from flwr_datasets.partitioner import NaturalIdPartitioner
fds = FederatedDataset(
dataset="flwrlabs/fed-isic2019",
partitioners={"train": NaturalIdPartitioner(partition_by="center"),
"test": NaturalIdPartitioner(partition_by="center")}
)
partition_train = fds.load_partition(partition_id=0, split="train")
partition_test = fds.load_partition(partition_id=0, split="test")
