Sharp Structure-Agnostic Lower Bounds for General Functional Estimation

arXiv — stat.MLMonday, December 22, 2025 at 5:00:00 AM
  • A recent study published on arXiv investigates the optimal error rates achievable by structure-agnostic estimators in nonparametric statistics, particularly focusing on the average treatment effect (ATE) in causal inference. The research highlights that doubly robust learning can achieve optimal structure-agnostic error rates, addressing limitations of classical methods that rely on strong structural assumptions.
  • This development is significant as it offers a pathway to improve the deployment of nonparametric estimators in real-world applications, potentially enhancing decision-making processes in various fields such as healthcare and economics.
  • The findings contribute to a broader discourse on the importance of flexible modeling approaches in machine learning and statistics, especially as the field increasingly seeks to mitigate biases and improve the robustness of estimations without relying on predefined structures.
