Controlling Counterfactual Harm in Decision Support Systems Based on Prediction Sets

NeurIPS 2024poster

Decision support systems based on prediction sets help humans solve multiclass classification tasks by narrowing down the set of potential label values to a subset of them, namely a prediction set, and asking them to always predict label values from the prediction sets. While this type of systems ha…

Designing Decision Support Systems using Counterfactual Prediction Sets

ICML 2024spotlight

Decision support systems for classification tasks are predominantly designed to predict the value of the ground truth labels. However, since their predictions are not perfect, these systems also need to make human experts understand when and how to use these predictions to update their own predictio…

Prediction-Powered Ranking of Large Language Models

NeurIPS 2024poster

Large language models are often ranked according to their level of alignment with human preferences---a model is better than other models if its outputs are more frequently preferred by humans. One of the popular ways to elicit human preferences utilizes pairwise comparisons between the outputs prov…

Towards Human-AI Complementarity with Prediction Sets

NeurIPS 2024poster

Decision support systems based on prediction sets have proven to be effective at helping human experts solve classification tasks. Rather than providing single-label predictions, these systems provide sets of label predictions constructed using conformal prediction, namely prediction sets, and ask h…

Improving Expert Predictions with Conformal Prediction

ICML 2023poster

Automated decision support systems promise to help human experts solve multiclass classification tasks more efficiently and accurately. However, existing systems typically require experts to understand when to cede agency to the system or when to exercise their own agency. Otherwise, the experts may…
