# Tea Sickness Dataset

This dataset contains images of tea leaves affected by seven common diseases, along with healthy examples. It is designed for use in machine learning tasks such as classification, particularly leveraging transfer learning techniques.

## Dataset Summary

The dataset includes tea leaves from eight categories:

| Label ID | Class Name       |
|----------|------------------|
| 0        | Anthracnose      |
| 1        | Algal Leaf Spot  |
| 2        | Bird Eye Spot    |
| 3        | Brown Blight     |
| 4        | Gray Blight      |
| 5        | Healthy          |
| 6        | Red Leaf Spot    |
| 7        | White Spot       |

Each class contains more than 100 images, captured from tea plants in the Johnstone Boiyon farm, Koiwa location, Bomet County, using a clone of 1510. The dataset is useful for developing models that can predict the presence of diseases in tea leaves, particularly in agricultural and sustainability contexts.

## Dataset Structure

### Features

- `image`: An RGB image of a tea leaf (PIL Image format)
- `label`: Class label as integer (0–7) with corresponding disease names

### Splits

| Split       | Number of Examples | Size (Bytes) |
|-------------|--------------------|--------------|
| Train       | 708                | 622,082,045  |
| Validation  | 88                 | 79,334,678   |
| Test        | 89                 | 79,495,048   |
| **Total**   | **885**            | **780,911,771** |
