# MUFAC (Machine Unlearning for Facial Age Classifier)
[](https://arxiv.org/abs/2311.02240)
This repository provides a **cleaned and resolution-aligned (128x128) version** of the MUFAC benchmark dataset.
---
## 📘 Description
A multi-class age classification dataset featuring over 86,000 Asian facial images with annotations for age groups and personal identities.
<img src="https://raw.githubusercontent.com/ndb796/MachineUnlearning/main/resources/MUFAC.png" width="700" alt="MUFAC examples"/>
- Preprocessed facial images (128×128 resolution)
- CSV files (`custom_train_dataset.csv`, etc.) for structured training/evaluation
- Separation of identity-forgettable vs. retained images (`forget_images`, `retain_images`)
- Suitable for benchmarking **machine unlearning** algorithms, especially in **task-agnostic setups**
It is specifically intended for experiments where **personal identities are selectively unlearned**, without degrading model utility on the original task (e.g., age classification).

## 🗂️ Dataset Structure
```
MUFAC/
├── forget_images/ # 1,500 images to be unlearned
├── retain_images/ # 8,525 images to retain
├── train_images_part1/ # 9,999 training images (part 1)
├── train_images_part2/ # 26 training images (part 2)
├── val_images/ # 1,539 validation images
├── test_images/ # 4,513 test images
├── fixed_test_dataset_negative/ # 5,000 identity-balanced test data (negative)
├── fixed_test_dataset_positive/ # 5,000 identity-balanced test data (positive)
├── fixed_val_dataset_negative/ # 5,000 identity-balanced val data (negative)
├── fixed_val_dataset_positive/ # 5,000 identity-balanced val data (positive)
├── custom_train_dataset.csv # CSV with image paths and labels
├── custom_val_dataset.csv # Validation CSV
└── custom_test_dataset.csv # Test CSV
```
- CSV files follow the format: `image_path`, `age_group`, `identity`, `forget_flag`, etc.
- All image paths are relative and usable with `datasets.Image()` or `PIL`.

## 🔹 How to Use
### Method 1: Git Clone (Recommended)
```python
git lfs install
git clone https://huggingface.co/datasets/Dasool/MUFAC
cd MUFAC
```
### Method 2: Using Hugging Face Hub API
```
from huggingface_hub import snapshot_download
# Download entire dataset
local_dir = snapshot_download("Dasool/MUFAC", repo_type="dataset")
print(f"Dataset downloaded to: {local_dir}")
```
### Method 3: Load CSV and Images
```
import pandas as pd
import os
from PIL import Image
# Load CSV
df = pd.read_csv("MUFAC/custom_train_dataset.csv")
print(f"Dataset size: {len(df)} samples")
print(df.head())
# Load sample image
sample_row = df.iloc[0]
img_path = os.path.join("MUFAC", sample_row["image_path"])
img = Image.open(img_path)
img.show()
```
