Understanding AI Bias and its Implications
Artificial Intelligence (AI) has revolutionized numerous industries, enhancing productivity, precision, and innovation. Yet, as we march forward into an increasingly digital era, we must grapple with the unintended consequences of AI — specifically, AI bias. AI bias, also known as Machine Learning or algorithm bias, is an emerging concern in the tech world that can lead to discriminatory practices and, subsequently, perpetuate systemic inequalities.
AI bias arises when an algorithm consistently produces prejudiced results due to flawed assumptions in the machine learning process. For instance, consider a facial recognition algorithm trained predominantly on data from white individuals. As a result, the system would more accurately recognize white faces, leading to a lower recognition rate for people of colour. Such disparities aren't intentional but often go unnoticed until they're programmed into the software, thus reinforcing existing biases.
Examples of bias in AI:
Unfairness in the US Healthcare System
In 2019, it was discovered that a predictive algorithm used in US hospitals to determine which patients might need extra care was unfairly favouring white patients over black ones. The algorithm was making its predictions based on how much patients had previously spent on healthcare, which unfortunately correlated with race. Despite having similar health issues, black individuals typically spent less on healthcare than their white counterparts.
Scientists and a health service provider, Optum, collaborated to reduce this bias in the AI system by 80%. But, if this issue had not been identified and questioned, the AI would have kept on unintentionally discriminating against black people.
Presenting CEOs as male only
In the US, women hold 27% of CEO positions. But in a 2015 study, only 11% of individuals shown in Google images for the term "CEO" were women. Anupam Datta from Carnegie Mellon University also found that Google's ad system often showed ads for high-paying jobs to men more than women.
Google claimed that this was because advertisers can choose who and where their ads are shown, with gender being one of the selectable criteria.
Some suggested that Google's algorithm independently decided that men are better suited for executive roles. However, Datta and his team think this could be due to user behaviour. If mostly men see and click on ads for high-paying jobs, the algorithm learns to show these ads primarily to men.
Building Unbiased AI: Education, Transparency, and Redress
To combat these biases, organizations need to consider implementing unbiased AI strategies. One way to achieve this is by promoting education about responsible AI amongst data scientists, ensuring that they understand the critical role of incorporating organizational values into their models.
As recommended by Kwartler, an AI expert, the principles of justice, fairness, and non-discrimination should be at the core of the AI design process. Transparency is another crucial element in fostering unbiased AI. Given that AI is often perceived as a "black box" where its internal workings remain hidden, consumers often have no understanding of how decisions are made. To address this, organizations should strive to make their AI models explainable, helping consumers grasp how decisions are being formed and the potential impacts.
Lastly, Kwartler suggests that companies establish a grievance process, providing individuals an avenue to voice concerns if they believe they've been unfairly treated by an AI system. This step not only aids in maintaining a check on the AI systems but also fosters trust and cooperation between companies and their consumers.
The Role of Government Regulation in Mitigating AI Bias
While organizations have a significant role in mitigating AI bias, the responsibility does not solely lie with them. According to DataRobot’s State of AI Bias report, 81% of business leaders are in favour of government regulation to define and prevent AI bias. Thoughtful regulation could indeed demystify the complexities surrounding AI bias, providing companies with a clear pathway to harness AI's full potential.
Regulation is particularly crucial in high-stakes areas such as education recommendations, credit allocations, employment, and surveillance, where AI bias can significantly impact individuals' lives. As AI becomes an integral part of products, services, and decision-making processes, government regulation is indispensable to safeguard consumers from potential bias and discrimination.
