Abstract

Public sector agencies in the United States are increasingly seeking to emulate business models of the private sector centered in efficiency, cost reduction, and innovation through the adoption of algorithmic systems. These data-driven systems purportedly improve decision-making; however, the public sector poses its own unique challenges where all decisions are mediated by policies, practices, and organizational constraints. Drawing upon a case study of the child-welfare system, I highlight how algorithms that do not account for these pertinent aspects of professional practice frustrate caseworkers and diminish the quality of human discretionary work. Why haven’t these algorithms lived up to expectations? And how might we be able to improve them? A human-centered research agenda can help us develop algorithms centered in social-ecological theories that support the decision-making processes of caseworkers, incorporate novel sources of data, as well as offer a means to evaluate algorithms in their real-world contexts.

Devansh Saxena is a doctoral candidate in the Department of Computer Science at Marquette University and a member of the Social and Ethical Computing Research Lab where he is co-advised by Dr. Shion Guha and Dr. Michael Zimmer. His research interests include investigating and developing algorithmic systems employed in the public sector, especially the Child-Welfare System. His current research examines collaborative child-welfare practices where decisions are mediated by policies, practices, and algorithms. His work is driven by Human-Centered Data Science and sits at the intersection of Human-Computer Interaction, Machine Learning, and FAccT (Fairness, Accountability, and Transparency in Sociotechnical Systems).

Abstract

Data has driven many technological advancements, while the ubiquitous collection and sharing of data has caused a privacy trust crisis in our society. Developers play a critical role in making apps that respect user privacy, yet many lack the necessary awareness, knowledge, and time to ensure their apps meet privacy requirements. How can we support average developers (who are oftentimes not privacy experts) in building privacy-friendly apps? In this talk, I will discuss how my research at the intersection of Privacy, HCI, and Software Engineering is engaging developers to better protect user privacy. I will talk about two main threads of my work: (1) empirical HCI studies to identify the challenges developers face in handling privacy requirements, and (2) system building work to tackle the identified challenges by building IDE plugins and breaking down privacy responsibilities into lightweight code annotating tasks. In the final remarks, I will discuss my future research agenda of creating a safe and trustworthy world by helping developers.

Abstract

Human-AI partnerships are increasingly commonplace. Yet, systems that rely on these partnerships are unable to effectively capture the dynamic needs of people, or explain complex AI reasoning and outputs. The resulting socio-technical gap has led to harmful outcomes such as propagation of biases against marginalized populations and missed edge cases in sensitive domains. My work follows the belief that for human-AI interaction to be effective and safe, technical development in AI must come in concert with an understanding of human-centric cognitive, social, and organizational phenomena. Using human-AI interaction in the context of ML-based decision-support systems as a case study, in this talk, I will discuss my work that explains why interpretability tools do not work in practice. Interpretability tools exacerbate the bounded nature of human rationality, encouraging people to apply cognitive and social heuristics. These heuristics serve as mental shortcuts that make people's decision-making faster by not having to carefully reason about the information being presented. Looking ahead, I will share my research agenda that incorporates social theories to design human-AI systems that not only take advantage of the complementarity between people and AI, but also account for the incompatibilities in how (much) they understand each other.

Harman Kaur is a PhD candidate in both the department of Computer Science and the School of Information at the University of Michigan, where she is advised by Eric Gilbert and Cliff Lampe. Her research interests lie in human-AI collaboration and interpretable ML. Specifically, she designs and evaluates human-AI systems such that they effectively incorporate what people and AI are each good at, but also mitigate harms by accounting for the incompatibilities between the two. She has published several papers at top-tier human-computer interaction venues, such as CHI, CSCW, IUI, UIST, and FAccT. She has also completed several internships at Microsoft Research and the Allen Institute for AI, and is a recipient of the Google PhD fellowship. Prior to Michigan, Harman received a BS in Computer Science from the University of Minnesota.

Abstract

Whose voices — whose labels — should a machine learning algorithm learn to emulate? For AI tasks ranging from online comment toxicity detection to poster design to medical treatment, different groups in society may have irreconcilable disagreements about what constitutes ground truth. Today’s supervised machine learning (ML) pipeline typically resolves these disagreements implicitly by aggregating over annotators’ opinions. This approach abstracts individual people out of the pipeline and collapses their labels into an aggregate pseudo-human, ignoring minority groups’ labels. In this talk, I will present Jury Learning: an interactive ML architecture that enables developers to explicitly reason over whose voice a model ought to emulate through the metaphor of a jury. Through our exploratory interface, practitioners can declaratively define which people or groups, in what proportion, determine the classifier's prediction. To evaluate models under societal disagreement, I will also present The Disagreement Deconvolution: a metric transformation showing how, in abstracting away the individual people that models impact, current metrics dramatically overstate the performance of many user-facing ML tasks. These components become building blocks of a new pipeline for encoding our goals and values in human-AI systems, which strives to bridge principles of human-computer interaction with the realities of machine learning.
