The document outlines how data-driven decision-making, particularly in marketing, is susceptible to the "winner's curse," a phenomenon where selected optimal policies are overvalued due to estimation errors. It explains that this upward bias occurs because algorithms tend to pick options that appear best in available data, even if their true performance is lower. The authors demonstr...

This paper introduces SPIRAL , a novel self-play framework designed to enhance the reasoning capabilities of large language models (LLMs) without relying on human supervision or pre-curated datasets.
