Introduction to AIF360

AIF360 (AI Fairness 360) is an open-source toolkit developed by IBM to help detect and mitigate bias in machine learning models. With the increasing reliance on AI systems, ensuring fairness in these models has become paramount. AIF360 provides a comprehensive suite of metrics and algorithms to assess and improve the fairness of AI systems.

Main Features of AIF360

• Bias Detection: AIF360 offers various metrics to evaluate bias in datasets and models.
• Mitigation Algorithms: The toolkit includes algorithms to mitigate bias in both pre-processing and post-processing stages.
• Extensive Documentation: Comprehensive guides and tutorials are available to help users understand and implement fairness techniques.
• Community Support: AIF360 has an active community contributing to its development and improvement.

Technical Architecture and Implementation

The architecture of AIF360 is designed to be modular and extensible. It consists of:

• Data Preprocessing: Tools for data cleaning and transformation to prepare datasets for fairness analysis.
• Fairness Metrics: A collection of metrics to quantify fairness across different dimensions.
• Mitigation Techniques: Algorithms that can be applied to datasets or models to reduce bias.

Here’s a simple code snippet demonstrating how to load a dataset and check for bias:

from aif360.datasets import StandardDataset

dataset = StandardDataset("path/to/dataset.csv")
print(dataset.protected_attributes)

Setup and Installation Process

To get started with AIF360, follow these steps:

1. Clone the repository from GitHub:

git clone https://github.com/Trusted-AI/AIF360.git
