Deep dives
The Problems with Deployed Machine Learning Systems
There is a need to address the real-world problems with deployed machine learning systems despite the focus on the dangers and risks of AI. Machine learning models in European welfare systems, for example, assign risk scores to welfare recipients, leading to investigations and potential benefit stoppages for those with high scores. Such systems generate suspicion and may unfairly target certain groups. Examples of the negative consequences of these systems include wrongful accusations and punitive investigations. The scale of welfare fraud is hard to quantify accurately, but estimates vary significantly, with consultancies often hyping up the estimates. The overall effectiveness and fairness of these systems are questionable, with evidence of biased outcomes and harsh treatment for those investigated.
Investigating Suspicion Machines in European Welfare Systems
Data journalists investigated the deployment of machine learning models, referred to as "suspicion machines," in European welfare systems. These models assign risk scores to welfare recipients to identify potential cases of welfare fraud. The investigation focused on one particular case in the Dutch city of Rotterdam. Through freedom of information requests, the journalists obtained the source code for the model and discovered flaws in its construction. The variables used in the model included demographic factors, language skills, and subjective assessments by caseworkers. The evaluation of the model revealed biases and disparate impacts on certain groups, leading to potentially unfair treatment of individuals.
Challenges in Obtaining Transparency and Accountability
In their reporting, the journalists encountered challenges in obtaining transparency and accountability from the government agencies using these machine learning models. Many agencies resisted requests for information, arguing concerns about potential fraudsters gaming the system. However, such arguments were debunked by academic research, highlighting the importance of transparency in understanding and scrutinizing these systems. The journalists also emphasized the need to examine each step of the modeling process, including the selection and construction of training data, feature engineering, and model evaluation. They argued for a comprehensive approach to algorithmic fairness that goes beyond just outcome fairness and encompasses the entire life cycle of the system.
Future Considerations and Ethical Debates
As the use of machine learning systems continues to expand, it is important to have broader discussions about transparency, accountability, and ethics. The journalists hope to spark conversations about whether the use of such systems is justified, considering the inherent biases and flaws they may exhibit. They also encourage practitioners to have a more holistic perspective on algorithmic fairness, considering not only outcome fairness but also the representativeness of training data, the construction of features, and the potential consequences of using these systems. The future of AI should involve critical evaluations of the underlying assumptions and implications to ensure fair and responsible use of these technologies.
In this enlightening episode, we delve deeper than the usual buzz surrounding AI’s perils, focusing instead on the tangible problems emerging from the use of machine learning algorithms across Europe. We explore “suspicion machines” — systems that assign scores to welfare program participants, estimating their likelihood of committing fraud. Join us as Justin and Gabriel share insights from their thorough investigation, which involved gaining access to one of these models and meticulously analyzing its behavior.
