OrderGrad: Optimizing Beyond the Mean with Order-Statistic Policy Gradient Estimation

OrderGrad introduces a family of gradient estimators that optimize order-statistic objectives rather than expected returns, enabling policy-gradient methods to directly target risk-sensitive metrics like Value-at-Risk, Conditional Value-at-Risk, and best-of-K outcomes. The method works as a plug-and-play reward transformation compatible with standard reinforcement learning algorithms, with applications demonstrated in LLM post-training and other domains.

Beyond Independent Manipulation: Individual Fairness-aware Strategic Classification with Peer Imitation

Researchers introduce Individual Fairness-aware Strategic Classification (IFSC), a framework addressing how agents manipulate features when machine learning models prioritize individual fairness. Unlike existing approaches assuming independent agent behavior, IFSC models peer-driven manipulation where agents imitate nearby positively-decided peers, using robust learning to handle uncertainty in peer observability.
