Fairness Indicators

Project description

Fairness Indicators


Fairness Indicators is designed to support teams in evaluating, improving, and comparing models for fairness concerns in partnership with the broader Tensorflow toolkit.

The tool is currently actively used internally by many of our products. We would love to partner with you to understand where Fairness Indicators is most useful, and where added functionality would be valuable. Please reach out at You can provide feedback and feature requests here.

What is Fairness Indicators?

Fairness Indicators enables easy computation of commonly-identified fairness metrics for binary and multiclass classifiers.

Many existing tools for evaluating fairness concerns don’t work well on large-scale datasets and models. At Google, it is important for us to have tools that can work on billion-user systems. Fairness Indicators will allow you to evaluate fairenss metrics across any size of use case.

In particular, Fairness Indicators includes the ability to:

  • Evaluate the distribution of datasets
  • Evaluate model performance, sliced across defined groups of users
    • Feel confident about your results with confidence intervals and evals at multiple thresholds
  • Dive deep into individual slices to explore root causes and opportunities for improvement

This case study, complete with videos and programming exercises, demonstrates how Fairness Indicators can be used on one of your own products to evaluate fairness concerns over time.


pip install fairness-indicators

The pip package includes:

Nightly Packages

Fairness Indicators also hosts nightly packages at on Google Cloud. To install the latest nightly package, please use the following command:

pip install -i fairness-indicators

This will install the nightly packages for the major dependencies of Fairness Indicators such as TensorFlow Data Validation (TFDV), TensorFlow Model Analysis (TFMA).

How can I use Fairness Indicators?

Tensorflow Models

  • Access Fairness Indicators as part of the Evaluator component in Tensorflow Extended [docs]
  • Access Fairness Indicators in Tensorboard when evaluating other real-time metrics [docs]

Not using existing Tensorflow tools? No worries!

  • Download the Fairness Indicators pip package, and use Tensorflow Model Analysis as a standalone tool [docs]
  • Model Agnostic TFMA enables you to compute Fairness Indicators based on the output of any model [docs]

Examples directory contains several examples.
