Dataset Card for Office-Home

The Office-Home dataset has been created to evaluate domain adaptation algorithms for object recognition using deep learning. It consists of images from 4 different domains: Artistic images, Clip Art, Product images and Real-World images. For each domain, the dataset contains images of 65 object categories found typically in Office and Home settings.

Dataset Details

The dataset information is based on the original dataset website: https://www.hemanthdv.org/officeHomeDataset.html. This implementation is based on the shared data (images + a CSV file).

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.

1. Install the package.

pip install flwr-datasets[vision]

2. Use the HF Dataset under the hood in Flower Datasets.

from flwr_datasets import FederatedDataset
from flwr_datasets.partitioner import IidPartitioner

fds = FederatedDataset(
    dataset="flwrlabs/office-home",
    partitioners={"train": IidPartitioner(num_partitions=10)}
)
partition = fds.load_partition(partition_id=0)

Dataset Structure

Data Instances

The first instance of the train split is presented below:

{
'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=640x640>,
 'domain': 'Real World',
 'label': 0
}

Data Split

DatasetDict({
    train: Dataset({
        features: ['image', 'domain', 'label'],
        num_rows: 15588
    })
})

Implementation details

The CSV file from the original source contains paths to samples with a subfolder named "Clock"; however, such data does not exist. However, if counting this category, there would be 66 classes. I believe this class was forgotten to be edited because there's a different class present in the dataset named "Alarm-Clock". This state better reflects the number of samples specified in the paper.
