Is your model predicting the past?

2022 · arXiv (Cornell University)

When does a machine learning model predict the future of individuals and when does it recite patterns that predate the individuals? In this work, we propose a distinction between these two pathways of prediction, supported …

Stochastic Optimization for Performative Prediction

2020 · arXiv (Cornell University)

In performative prediction, the choice of a model influences the distribution of future data, typically through actions taken based on the model's predictions. We initiate the study of stochastic optimization for performative prediction. What sets …
