DetoxAI is a Python package for debiasing neural networks in image classification tasks. It transforms biased models into fair and balanced ones with minimal code changes.
Website and demo: https://detoxai.github.io	Documentation: https://detoxai.readthedocs.io

Installation

Install DetoxAI from PyPI:

pip install detoxai

Quickstart

import detoxai

model = ...
dataloader = ...  # should output (input, label, protected attributes)

corrected = detoxai.debias(model, dataloader)

metrics = corrected["SAVANIAFT"].get_all_metrics()
model = corrected["SAVANIAFT"].get_model()

Minimal runnable example:

import torch
import torchvision
import detoxai

model = torchvision.models.resnet18(pretrained=True)
model.fc = torch.nn.Linear(model.fc.in_features, 2)

X = torch.rand(128, 3, 224, 224)
Y = torch.randint(0, 2, size=(128,))
PA = torch.randint(0, 2, size=(128,))

dataloader = torch.utils.data.DataLoader(list(zip(X, Y, PA)), batch_size=32)

results: dict[str, detoxai.CorrectionResult] = detoxai.debias(model, dataloader)

More examples: see examples/ folder.

Before/After Saliency Map	Aggregate Bias Visualization
Saliency maps show model focus during classification.	Aggregate visualizations show focus shift after debiasing.

💻 Simple API

• Works with existing PyTorch models
• Standard dataloaders
• Single function call for multiple debiasing methods
