Examples of Artificial Intelligence Bias in Algorithms

Introduction: AI Bias and Societal Biases

AI systems can reflect and amplify existing societal biases. Because AI models are trained on data created by humans, they can inherit and perpetuate biases present in that data. This can lead to unfair or discriminatory outcomes. This tutorial explores examples of AI bias demonstrated by several algorithms.

Understanding AI Bias

AI bias, also called machine learning bias or algorithm bias, refers to systematic errors in AI systems resulting from biased data or algorithms. These biases can lead to unfair or discriminatory outcomes, reducing AI's accuracy and effectiveness. AI bias can damage an organization's reputation and erode public trust in AI.

Algorithms Demonstrating AI Bias

1. COMPAS Algorithm (Criminal Justice)

The Correctional Offender Management Profiling for Alternative Sanctions (COMPAS) algorithm, used in US courts to predict recidivism (re-offending), was found to be biased against Black individuals. It incorrectly classified Black defendants as higher risk more often than white defendants, even when controlling for factors like criminal history.

2. PredPol Algorithm (Predictive Policing)

PredPol, a predictive policing algorithm, was found to disproportionately direct police resources towards neighborhoods with higher concentrations of racial minorities, regardless of actual crime rates. This bias was partly due to a feedback loop: more police presence in certain areas led to more reported crimes, reinforcing the algorithm's biased predictions.

3. Amazon's Recruiting Engine

Amazon's AI-based recruiting tool exhibited bias against women. Trained on historical hiring data that reflected existing gender bias, the algorithm penalized resumes containing words like "women" and downgraded applications from women's colleges. Amazon ultimately abandoned the algorithm.

4. Google Photos Algorithm

(An example of bias in Google's photo-tagging algorithm, likely mislabeling photos of people of color, would be added here.)

Mitigating AI Bias

Addressing AI bias requires a multi-pronged approach:

• Careful Data Curation: Using diverse and representative datasets for training AI models. Identifying and removing biases in the data itself.
• Algorithmic Design: Developing algorithms that explicitly address and mitigate bias.
• Ongoing Monitoring and Evaluation: Continuously assessing AI systems for bias and taking corrective actions.
• Transparency and Explainability: Making AI decision-making processes understandable to identify and correct sources of bias.
• Human Oversight: Ensuring human review of AI-driven decisions, particularly in high-stakes applications.

Further Examples of Algorithmic Bias in AI

Bias in Google Photos' Image Labeling

Google Photos uses a convolutional neural network (CNN) trained on a massive image dataset to automatically label images. However, this system was found to exhibit racial bias, mislabeling photos of Black individuals as gorillas. Google acknowledged the problem, apologized, and took steps to mitigate it by removing gorillas and other primates from the labeling vocabulary. This highlights the limitations of even sophisticated AI systems and the ongoing challenges of eliminating bias in AI algorithms.

Bias in IDEMIA's Facial Recognition Algorithm

IDEMIA's facial recognition algorithm, used by law enforcement agencies globally, was found to have significantly higher error rates for Black women compared to other demographic groups. A study by the National Institute of Standards and Technology (NIST) revealed that the false match rate for Black women was ten times higher than for white women. IDEMIA claims that the algorithms tested by NIST were not commercially deployed versions and that their systems are continuously being improved. This example underscores the critical need for ongoing testing and refinement of AI systems to eliminate bias and ensure fairness.
