+# Dataset Card for Caltech 101
+
+This dataset contains images of objects from 101 distinct categories, with each category comprising approximately 40 to 800 images. The majority of categories include around 50 images each. The images were collected in September 2003 by Fei-Fei Li, Marco Andreetto, and Marc’Aurelio Ranzato. Each image has an approximate resolution of 300 x 200 pixels.

+
+## Use in FL
+
+In order to prepare the dataset for the FL settings, we recommend using [Flower Dataset](https://flower.ai/docs/datasets/) (flwr-datasets) for the dataset download and partitioning and [Flower](https://flower.ai/docs/framework/) (flwr) for conducting FL experiments.
+
+To partition the dataset, do the following. 
+1. Install the package.
+```bash
+pip install flwr-datasets[vision]
+```
+2. Use the HF Dataset under the hood in Flower Datasets.
+```python
+from flwr_datasets import FederatedDataset
+from flwr_datasets.partitioner import IidPartitioner
+
+fds = FederatedDataset(
+    dataset="flwrlabs/caltech101",
+    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=397x150>,
+ 'label': 1
+}
+```
+### Data Split
+
+```
+DatasetDict({
+    train: Dataset({
+        features: ['image', 'label'],
+        num_rows: 8677
+    })
+})
+```
+
+## Implementation details
+
+Note that in this implementation, the string labels are first transformed into lowercase and then sorted alphabetically before providing the integer mapping. This methodology can vary across implementations. 
+
+## Citation
+
+When working with the Office-Home dataset, please cite the original paper. 
+If you're using this dataset with Flower Datasets and Flower, cite Flower.
