Summary

The "Partially Performative Prediction" framework, published on 2026-06-05, generalizes performative prediction by integrating both endogenous and exogenous sources of distribution shift. Traditional performative prediction focuses on feedback loops where a deployed model alters the population it predicts, causing an endogenous shift. In contrast, classical distribution shift models typically assume exogenous changes. This new framework acknowledges that real-world data distributions evolve due to both the model's influence on decisions and independent external processes. It extends core concepts like performative stability and performative optimality into online analogues designed to track these evolving, partially performative environments. The research also analyzes practical learning heuristics, such as repeated retraining, to determine their effectiveness in adapting to these complex environments.

Key takeaway

For Machine Learning Engineers deploying models in dynamic, consequential domains, you must recognize that data distribution shifts are rarely singular. Your models will influence future data, but external factors also cause drift. Therefore, you should evaluate learning heuristics like repeated retraining within a partially performative framework to ensure your systems adapt effectively to both endogenous and exogenous changes, maintaining robust performance over time.

Key insights

Partially performative prediction integrates both endogenous model influence and exogenous environmental drift in predictive systems.

Principles

• Distribution shift often combines model-induced and external factors.
• Online analogues are crucial for tracking evolving performative environments.
• Learning heuristics must adapt to mixed endogenous/exogenous shifts.

In practice
