### Dataset Summary

ViTucano-Pretrain is a translation of the original [liuhaotian/LLaVA-Pretrain](https://huggingface.co./datasets/liuhaotian/LLaVA-Pretrain), obtained via Google's translation API. LLaVA Visual Instruct Pretrain LCS-558K is a subset of the LAION/CC/SBU dataset, filtered with a more balanced concept coverage distribution. This dataset was used to train the **ViTucano**, our first attempt at creating a vision assistant natively pretrained in Portuguese. **ViTucano** is built on top of the [Tucano series](https://arxiv.org/abs/2411.07854) using the [TinyLLaVA Factory](https://arxiv.org/abs/2405.11788).

### Supported Tasks and Leaderboards

This dataset can be utilized for tasks involving language modeling and visual instruction tunning.

### Languages

Portuguese.

## Dataset Structure

### Data Instances

The dataset consists of the following features:

- **id:** an identifier (name of the respective file) for that image.
- **image:** the path to the file in the original folder configuration.
- **conversations:** a list of dictionaries, where each dictionary represents a message or an entry in a conversation.
- **blip_caption:** the original BLIP caption.
- **url:** the url of the corresponding image.

### Data Fields

```python
{
    "id": "004539375",
    "image": "train/00453/004539375.jpg",
    "conversations": [
        {
            "from": "human",
            "value": "Renderize um resumo claro e conciso da foto.\n<image>"
        },
        {
            "from": "gpt",
            "value": "Selecione móveis de luxo 3 - colchão de espuma de memória de gel de polegada"
        }
    ],
    "blip_caption": "Selecione móveis de luxo 3 - colchão de espuma de memória de gel de polegada",
    "url": "http://ec1.ostkcdn.com/images/products/8111140/P15459545.jpg"
}
```

### Data Splits

Available splits are `train`.

To use this dataset, you will need to download both the `data-pretraining.json` and `images.zip` files available in this folder:

```bash
wget https://huggingface.co./datasets/TucanoBR/ViTucano-Pretrain/resolve/main/data-pretraining.json
wget https://huggingface.co./datasets/TucanoBR/ViTucano-Pretrain/resolve/main/images.zip
```

You can also do this via the `huggingface_hub` library:

```python
from huggingface_hub import snapshot_download

snapshot_download(repo_id="ViTucano-Pretrain", repo_type="dataset")
```

Unzip the images in a way that you get this folder structure (e.g., `unzip images.zip -d "path/to/train"`):

```bash
├── train
    ├── 00000
    ├── 00001
    ├── 00002
    └── etc ...
```

Done! The data is ready to train your projector.

## Dataset Creation

### Curation Rationale

This dataset is a translation of the original [liuhaotian/LLaVA-Pretrain](https://huggingface.co./datasets/liuhaotian/LLaVA-Pretrain) obtained via Google's translation API.

### Source Data

#### Who are the source language producers?

All text samples translated from English to Portuguese.

### Annotations

#### Annotation process

Read this [dataset card](https://huggingface.co./datasets/liuhaotian/LLaVA-Pretrain) for more information.

#### Who are the annotators?

Read this [dataset card](https://huggingface.co./datasets/liuhaotian/LLaVA-Pretrain) for more information.

### Considerations for Using the Data

**Warning:** This dataset may contain NSFW (Not Safe For Work) content, including explicit images and text captions with offensive/sensitive language.

### Other Known Limitations

This dataset has has been translated using translation engines, potentially resulting in corrupted samples. While useful for quickly converting text between languages, translation engines often struggle with accurately preserving the syntax, semantics, and context of certain languages.
