The Interactive Visual Data Analysis (IVDA) Group at the University of Zurich is seeking a talented Post-Doc (m/f/d) at the intersection of visual analytics, interactive machine learning, and human-centered AI. Together, we will develop novel approaches for the characterization, design, and evaluation of interactive visual data analysis solutions that combine the strengths of both humans and algorithms. This position is particularly suitable for candidates with interests/experience in human preference elicitation and multi-criteria decision support, which we will study for the case of item ranking challenges.
Multi-criteria decision support through item ranking is an understudied research direction. Current solutions exhibit considerable limitations, primarily due to their inability to meet the multi-faceted nature of human decision-making. Choosing between thousands of relevant items is a common task, where people are left alone with the need to express and balance multiple desirable preferences at once. Item rankings are a popular and universal approach to structuring unorganized item collections by multiple criteria at the same time. In interactive solutions, people can express multiple preferences, used by algorithms to compute human-centered and personal rankings. Visual Analytics (VA) is a field of research that supports complex human decision-making tasks by bringing together human intellectuality with the computational power of algorithms in effective human-in-the-loop approaches.
In this project, we will demonstrate how cutting-edge VA principles can be transferred to item ranking, to overcome remaining challenges, demonstrate effective and efficient interactive ranking creation solutions, and empower broad audiences. Limitations of ranking systems mainly include their incompatibility for the elicitation of item- and attribute-based preferences, insufficient handling of user-introduced uncertainty, inadequate guidance for engaging with large item sets, lacking interaction histories, inefficient human-centric feedback loops, or a lack of explanations and transparency of ranking algorithms, thus creating a disconnect between the technology and nuanced user needs. Finally, interactive ranking creation does not yet make use of interfaces for eliciting implicit user preferences, e.g., in textual form using large language models.
