arXiv:2602.24207v2 Announce Type: replace Abstract: The use of algorithmic predictions in decision-making leads to a feedback loop where the models we deploy actively influence the data distributions we see, and later use to retrain on. This dynamic was formalized by Perdomo et al. 2020 in their work on performative prediction. Our main result is an unconditional reduction showing that any no-regret algorithm deployed in performative settings converges to a (mixed) performatively stable equilibrium: a solution in which models actively shape data distributions in ways that their own predictions
The academic formalization of performative prediction is rapidly maturing as AI systems are deployed in real-world, dynamic environments.
This research provides a theoretical underpinning for understanding how AI models interact with and reshape the data they are trained on, which is critical for robust and ethical AI deployment.
The understanding of AI model stability in dynamic settings is more formalized, offering pathways to design algorithms that converge to stable equilibria rather than chaotic outcomes.

Online algorithms will increasingly be designed with performative stability in mind, leading to more predictable and robust AI systems.
This improved understanding of feedback loops could lead to regulatory frameworks emphasizing dynamic stability and responsible AI deployment.
The concept of performative prediction might extend beyond AI into other areas where models influence outcomes, such as economics or social policy.
