# Typhoon - Image Classification Dataset

This dataset comes from [PTIT AI Challenge](https://aichallenge.ptit.edu.vn/) and is organized for a multi-class image classification task focusing on tropical cyclone (typhoon) intensity estimation.

## Dataset Structure

The directory structure is organized as follows:

```text
train/
    ├── images/
    │   ├── image1.jpg
    │   └── ...
    └── annotations.csv (only present in the train folder)
```

The `public_test` and `private_test` sets are used to evaluate and score the participating teams after the training phase is completed.

## Labels

The dataset categorizes images into 5 classes based on the intensity of the storm:

- **0: No Storm** (`is_negative=True`)
- **1: TD** (Tropical Depression)
- **2: TS** (Tropical Storm)
- **3: STS** (Severe Tropical Storm)
- **4: TY** (Typhoon)

## Dataset Characteristics

For a more detailed data analysis, please refer to the `data_analysis.ipynb` notebook.

- **Total samples:** 8385
- **Total classes:** 5

### Class Distribution

The distribution of images across the different classes is as follows:

| Class | Description | Count | Percentage |
| :--- | :--- | :--- | :--- |
| **0** | No Storm | 2548 images | 30.4% |
| **1** | TD (Tropical Depression) | 1931 images | 23.0% |
| **2** | TS (Tropical Storm) | 1583 images | 18.9% |
| **3** | STS (Severe Tropical Storm) | 770 images | 9.2% |
| **4** | TY (Typhoon) | 1553 images | 18.5% |
