# AI Challenge CV Dataset Description

This dataset comes from [https://aichallenge.ptit.edu.vn/](https://aichallenge.ptit.edu.vn/) and is organized for a multi-class video classification task focusing on Vietnamese Sign Language.

---

## 🛠 Dataset Viewer Configuration

This dataset supports Hugging Face **Dataset Viewer**. The dataset structure and video paths are mapped via `dataset_metadata.csv`.

### Expected CSV Structure

To ensure the Dataset Viewer renders correctly, your `dataset_metadata.csv` should follow this format:
| video_file | label |

| :--- | :--- |

| `train/Ăn/video_001.mp4` | `Ăn` |
| `train/Ban đêm/video_002.mp4` | `Ban đêm` |

---

## Dataset Structure

The `train` folder contains training data organized in a class-based directory structure.

- each subfolder corresponds to a class label for the classification problem
- each subfolder name is the class label, for example: `Ăn`, `Ban đêm`, `Bạn thân`, `Bệnh viện`, `Virus`, `Xe đạp`, `Xin lỗi`, ...
- each folder contains many short MP4 video clips

## What this means

- Each subfolder holds examples belonging to that label.
- The dataset is arranged as a label-directory dataset, which is ideal for multi-class classification tasks.
- Although the training set is organized by folder labels, the actual examples are short video files in MP4 format.

## Representative Labels

Some notable class labels in `train` include:

- Ăn
- Ăn mừng
- An ủi
- Áp dụng
- Ban đêm
- Bạn thân
- Bệnh viện
- Bộ y tế
- Con gấu
- Cứu
- Học sinh
- Khẩu trang
- Lây bệnh
- Nghe
- Nghỉ ngơi
- Phòng xét nghiệm
- Sốt
- Sử dụng
- Thức ăn
- Thương
- Xe đạp
- Ô tô
- Xin lỗi
- Xuất viện
- ...

## Summary

In summary, the training dataset is organized by label directories and is well suited for multi-class classification problems. For a deeper inspection, open each label subfolder to see the number of samples and the exact file formats inside.
