### LexicaDataset

LexicaDataset is a large-scale text-to-image prompt dataset shared in [[USENIX'24] Prompt Stealing Attacks Against Text-to-Image Generation Models](https://arxiv.org/abs/2302.09923).
It contains **61,467 prompt-image pairs** collected from [Lexica](https://lexica.art/).
All prompts are curated by real users and images are generated by Stable Diffusion.
Data collection details can be found in the paper.

### Data Splits

We randomly sample 80% of a dataset as the training dataset and the rest 20% as the testing dataset.

### Load LexicaDataset

You can use the Hugging Face [`Datasets`](https://huggingface.co/docs/datasets/quickstart) library to easily load prompts and images from LexicaDataset.

```python
import numpy as np
from datasets import load_dataset

trainset = load_dataset('vera365/lexica_dataset', split='train')
testset  = load_dataset('vera365/lexica_dataset', split='test')
```

### Metadata Schema

`trainset` and `testset` share the same schema.

| Column              | Type       | Description                                                  |
| :------------------ | :--------- | :----------------------------------------------------------- |
| `image`             | `image`    | The generated image                                          |
| `prompt`            | `string`   | The text prompt used to generate this image                  |
| `id`                | `string`   | Image UUID                                                   |
| `promptid`          | `string`   | Prompt UUID                                                  |
| `width`             | `uint16`   | Image width                                                  |
| `height`            | `uint16`   | Image height                                                 |
| `seed`              | `uint32`   | Random seed used to generate this image.                     |
| `grid`              | `bool`     | Whether the image is composed of multiple smaller images arranged in a grid |
| `model`             | `string`   | Model used to generate the image                             |
| `nsfw`              | `string`   | Whether the image is NSFW                                    |
| `subject`           | `string`   | the subject/object depicted in the image, extracted from the prompt |
| `modifier10`        | `sequence` | Modifiers in the prompt that appear more than 10 times in the whole dataset. We regard them as labels to train the modifier detector |
| `modifier10_vector` | `sequence` | One-hot vector of `modifier10`                               |
