# Background Dataset — `Horama/classif_background`

![Task](https://img.shields.io/badge/task-image--classification-blue)
![Type](https://img.shields.io/badge/class-null-lightgrey)

Dataset of images **without animals**, used as a background class.

This dataset is part of the merged dataset:
👉 `Horama/classif_merged_187`

---

## Dataset Summary

- Images with no animals present
- Label: `null`

---

## Intended Use

- Train models to predict **“no animal”**
- Reduce false positives
- Improve classifier robustness

---

## Data Source

- Derived from COCO dataset

---

## Splits

Predefined splits are preserved from the original dataset.

---

## Data Processing

Same preprocessing pipeline as:
👉 `Horama/classif_merged_187`

---

## Dataset Structure

Data is stored as **zstd-compressed Parquet shards**.

Images are stored as **raw bytes** and decoded on-the-fly.

---

## Row format

```python
{
    "image": <PIL Image>,  # stored as raw bytes
    "label": "null",
    "distance": str,
}
```

---

## Biases & Limitations
May not reflect real-world negative samples
Distribution differs from production pipeline

---

## Ethical Considerations
Inherits constraints from COCO dataset

---

## License

Follows COCO dataset licensing.
