FairML Datasets

PyPI Tests

A comprehensive Python package for loading, processing, and working with datasets used in fair classification.

Overview

The dataset preprocessing pipeline supported by the package.

FairML Datasets provides tools and interfaces to download, load, transform, and analyze the datasets in the FairGround corpus. It handles sensitive attributes and facilitates fairness-aware machine learning experiments. The package supports the full data processing pipeline from downloading data all the way to splitting data for ML training.

Key Features

  • 📦 Loading: Easily download, load and prepare any of the 44 supported datasets in the corpus.
  • 🗂️ Collections: Conveneiently use any of our prespecified collections which have been developed to maximize diversity in algorithmic performance.
  • 🔄 Multi-Dataset Support: Easily evaluate your algorithm on one scenario, five or fourty using a simple loop.
  • ⚙️ Processing: Automatically apply dataset (pre)processing with configurable choices and defaults available.
  • 📊 Metadata Generation: Automatically calculate rich metadata features for datasets.
  • 💻 Command-line Interface: Access common operations without writing code.

Installation

pip install fairml-datasets

Or using uv:

uv add fairml-datasets

Quick Start

from fairml_datasets import Dataset

# Access a specific dataset by ID directly
dataset = Dataset.from_id("folktables_acsincome_small")

# Load the dataset
df = dataset.load()

# Check sensitive attributes
print(f"Sensitive columns: {dataset.sensitive_columns}")

# Transform the dataset
df_transformed, info = dataset.transform(df)

# Create train/test/validation split
df_train, df_test, df_val = dataset.train_test_val_split(df_transformed)

Command-line Usage

The package provides a command-line interface for common operations:

# Generate and export metadata
python -m fairml_datasets metadata

# Export datasets in various processing stages
python -m fairml_datasets export-datasets --stage prepared

# Export dataset citations in BibTeX format
python -m fairml_datasets export-citations
