# Dataset Card for LVIS-35k
This is a [FiftyOne](https://github.com/voxel51/fiftyone) dataset with 35000 samples.
**NOTE:** This is only a 35k sample subset of the full dataset. The notebook recipe for creating this, and the full, dataset can be found [here](https://colab.research.google.com/drive/1SmdZPWtLhNis_cCRnO9WKKZQ9OaP_C_d)
## Installation
If you haven’t already, install FiftyOne:
```bash
pip install -U fiftyone
```
## Usage
```python
import fiftyone as fo
import fiftyone.utils.huggingface as fouh
# Load the dataset
# Note: other available arguments include 'max_samples', etc
dataset = fouh.load_from_hub("Voxel51/LVIS")
# Launch the App
session = fo.launch_app(dataset)
```
## Dataset Details
### Dataset Description
LVIS (pronounced ‘el-vis’) is a dataset for large vocabulary instance segmentation, introduced by researchers from Facebook AI.
- It contains annotations for over 1000 object categories across 164k images. The full dataset is planned to have ~2 million high-quality instance segmentation masks.
- The categories in LVIS follow a natural long-tail distribution, with a few common categories and many rare ones with few training examples. This long tail poses a challenge for current state-of-the-art object detection methods which struggle with low-sample categories.
- The vocabulary was constructed iteratively, starting from 8.8k concrete noun synsets in WordNet and filtering down to the final set[4].
- LVIS can be used for instance segmentation, semantic segmentation, and object detection tasks. The dataset aims to focus the research community on the open challenge of long-tail object recognition.
In summary, LVIS is a large-scale, high-quality dataset that targets the difficult problem of learning segmentation models for various object categories, including many rare ones. It is freely available for research use.
