Unlearn Diff

Unlearn Diff is an open-source Python package designed to streamline the development of unlearning algorithms and establish a standardized evaluation pipeline for diffusion models. It provides researchers and practitioners with tools to implement, evaluate, and extend unlearning algorithms effectively.

Documentation

You can find the full documentation for this project at the following URL: https://ramailotech.github.io/msu_unlearningalgorithm/

Features

• Comprehensive Algorithm Support: Includes commonly used concept erasing and machine unlearning algorithms tailored for diffusion models. Each algorithm is encapsulated and standardized in terms of input-output formats.

• Automated Evaluation: Supports automatic evaluation on datasets like UnlearnCanvas or IP2P. Performs standard and adversarial evaluations, outputting metrics as detailed in UnlearnCanvas and UnlearnDiffAtk.

• Extensibility: Designed for easy integration of new unlearning algorithms, attack methods, defense mechanisms, and datasets with minimal modifications.

Datasets

We use the Unlearn Canvas benchmark dataset, available here. Currently, the algorithms are trained using 5 images belonging to the themes of Abstractionism and Architectures.

Usage

This section contains the usage guide for the package.

Installation

Prerequisities

Ensure conda is installed on your system. You can install Miniconda or Anaconda:

After installing conda, ensure it is available in your PATH by running. You may require to restart the terminal session:

Before installing the unlearn_diff package, follow these steps to set up your environment correctly. These instructions ensure compatibility with the required dependencies, including Python, PyTorch, and ONNX Runtime.

Step-by-Step Setup:

1. Create a Conda Environment Create a new Conda environment named myenv with Python 3.8.5:

conda create -n myenv python=3.8.5

2. Activate the Environment Activate the environment to work within it:

conda activate myenv

3. Install Core Dependencies Install PyTorch, torchvision, CUDA Toolkit, and ONNX Runtime with specific versions:

conda install pytorch==1.11.0 torchvision==0.12.0 cudatoolkit=11.3 onnxruntime==1.16.3 -c pytorch -c conda-forge

4. Install our unlearn_diff Package using pip:

pip install unlearn_diff

5. Install Additional Git Dependencies:

After installing unlearn_diff, install the following Git-based dependencies in the same Conda environment to ensure full functionality:

Run Train

Each algorithm has their own script to run the algorithm, Some also have different process all together. Follow usage section in readme for the algorithm you want to run with the help of the github repository. You will need to run the code snippet provided in usage section with necessary configuration passed.

Example usage for erase_diff algorithm (CompVis model)

The default configuration for training is provided by erase_diff_train_mu. You can run the training with the default settings as follows:

Using the Default Configuration

frommu.algorithms.erase_diff.algorithmimportEraseDiffAlgorithmfrommu.algorithms.erase_diff.configsimporterase_diff_train_mualgorithm=EraseDiffAlgorithm(
erase_diff_train_mu
)
algorithm.run()

Overriding the Default Configuration

If you need to override the existing configuration settings, you can specify your custom parameters (such as ckpt_path and raw_dataset_dir) directly when initializing the algorithm. For example:

frommu.algorithms.erase_diff.algorithmimportEraseDiffAlgorithmfrommu.algorithms.erase_diff.configsimporterase_diff_train_mualgorithm=EraseDiffAlgorithm(
erase_diff_train_mu,
ckpt_path="/home/ubuntu/Projects/UnlearnCanvas/UnlearnCanvas/machine_unlearning/models/compvis/style50/compvis.ckpt", #replace it with your ckpt pathraw_dataset_dir="data/quick-canvas-dataset/sample",
use_sample=True, #uses sample datasettemplate_name="Abstractionism",
dataset_type="unlearncanvas",
devices="0"
)
algorithm.run()

Note: When fine-tuning the model, if you want to use a sample dataset, set use_sample=True (default).Otherwise, set use_sample=False to use the full dataset.

Machine unlearning with i2p dataset

frommu.algorithms.erase_diff.algorithmimportEraseDiffAlgorithmfrommu.algorithms.erase_diff.configsimporterase_diff_train_i2palgorithm=EraseDiffAlgorithm(
erase_diff_train_i2p,
ckpt_path="/home/ubuntu/Projects/UnlearnCanvas/UnlearnCanvas/machine_unlearning/models/compvis/style50/compvis.ckpt", #replace it with your ckpt pathraw_dataset_dir="data/i2p-dataset/sample",
num_samples=1,
dataset_type="i2p",
template="i2p",
template_name="self-harm",
use_sample=True, #uses sample datasetdevices="0"
)
algorithm.run()

Run on your own dataset

Step-1: Generate your own dataset

generate_images_for_prompts --model_path models/diffuser/style50 --csv_path data/prompts/generic_data.csv

Note:

• generate_images_for_prompts: This command invokes the image generation script. It uses a diffusion model to generate images based on textual prompts.

• --model_path: Specifies the path to the diffusion model to be used for image generation. In this example, the model is located at models/diffuser/style50.

• --csv_path: Provides the path to a CSV file containing the prompts. Each prompt in this CSV will be used to generate an image, allowing you to build a dataset tailored to your needs.

Step-2: Train on your own dataset

frommu.algorithms.erase_diff.algorithmimportEraseDiffAlgorithmfrommu.algorithms.erase_diff.configsimporterase_diff_train_i2palgorithm=EraseDiffAlgorithm(
erase_diff_train_i2p,
ckpt_path="/home/ubuntu/Projects/UnlearnCanvas/UnlearnCanvas/machine_unlearning/models/compvis/style50/compvis.ckpt", #replace it with your ckpt pathraw_dataset_dir="data/generic_data",
num_samples=1,
dataset_type="generic", #add the dataset type as generictemplate_name="self-harm", #concept to eraseuse_sample=True, #uses sample datasetdevices="0"
)
algorithm.run()

Evaluation:

1. Evaluate using unlearn canvas dataset:

Note: Currently it supports evaluation for unlearn canvas dataset. I2p and generic dataset support needs to be added.
