    Write It Like You See It

    Clinical notes are becoming an increasingly important data source for machine learning (ML) applications in healthcare. Prior research has shown that deploying ML models can perpetuate existing biases against racial minorities, as bias can be implicitly embedded in data. In this study, we investigate the level of implicit race information available to ML models and human experts and the implications of model-detectable differences in clinical notes. Read more.

    Beyond Fairness: Reparative Algorithms to Address Historical Injustices of Housing Discrimination in the US

    Fairness in Machine Learning (ML) has mostly focused on interrogating the fairness of a particular decision point with assumptions made that the people represented in the data have been fairly treated throughout history. However, fairness cannot be ultimately achieved if such assumptions are not valid. This is the case for mortgage lending discrimination in the US, which should be critically understood as the result of historically accumulated injustices that were enacted through public policies and private practices including redlining, racial covenants, exclusionary zoning, and predatory inclusion, among others. To emphasize such issues, we introduce case studies using contemporary mortgage lending data as well as historical census data in the US. Read More.

    Structural Factors and Racial Disparities in Evictions

    What are mechanisms that contribute to racial disparities in evictions? How can we use causal inference methods to evaluate policies that are aimed at reducing evictions? In this poster presentation, authors Aurora Zhang and Anette "Peko" Hosoi find that even after accounting for economic characteristics such as poverty rate, median income, median rent, that there is a significant relationship between neighborhood racial composition and eviction rate.

    Characterization of Affordable Housing Properties and Policy by Reported Concerns: Boston’s RentSmart Dataset

    Because of the Housing and Urban Renewal Act of 1983, contracts to receive rental subsidies are now renewable but cannot be awarded to new companies. The study hypothesizes that the experiences of residents with property managers are a function of the amount/lack of competition for contracts. Read more.

  • Real Time Mixture-Based Predictions

    As discussed in a previous post, we already know mixtures matter when it comes to COVID-19. Here, we take this idea a step further. We show that the spread of COVID-19 in the United States can meaningfully be described as the mixture of two outbreaks, and use this perspective to form predictions of how the pandemic will evolve. To show both the benefits and drawbacks of our curve-fitting method, we’ve developed a real-time, interactive dashboard for predictions.

    Ali Jadbabaie and Peko Hosoi discuss Isolat (Webinar)

    IDSS Faculty members Ali Jadbabaie and Peko Hosoi were recently invited to the Rafael del Pino Foundation (Madrid, Spain) to discuss the IDSS COVID-19 Collaboration (Isolat). In a conversation led by MIT graduate student Juncal Arbelaiz, they talked about the main goals of the initiative, the importance of multidisciplinary research, and the value of data and modeling to inform policy-making that addresses the COVID-19 crisis.


Institute for Data, Systems, and Society (IDSS) is committed to addressing complex societal challenges by advancing education and research at the intersection of statistics, data science, information and decision systems, and social sciences.
