Unified Inference Framework for Single and Multi-Player Performative Prediction: Method and Asymptotic Optimality
Zhixian Zhang, Xiaotian Hou, Linjun Zhang
Performative prediction characterizes environments where predictive models alter the very data distributions they aim to forecast, triggering complex feedback loops. While prior re…
PieArena: Ranking and Profiling Language Agents in Realistic Negotiation Scenarios
Chris Zhu, Sasha Cui, Will Sanok Dufallo +4
We present an in-depth evaluation of LLMs' ability to negotiate, a central business task requiring strategic reasoning, theory of mind, and economic value creation. To do so, we in…
Evaluating LLMs When They Do Not Know the Answer: Statistical Evaluation of Mathematical Reasoning via Comparative Signals
Zihan Dong, Zhixian Zhang, Yang Zhou +3
Evaluating mathematical reasoning in LLMs is constrained by limited benchmark sizes and inherent model stochasticity, yielding high-variance accuracy estimates and unstable ranking…
Bias-Corrected Data Synthesis for Imbalanced Learning
Pengfei Lyu, Zhengchi Ma, Linjun Zhang +1
Class imbalance complicates probabilistic classification because standard training objectives emphasize majority-class performance. Synthetic oversampling can reduce imbalance, but…
Double Cross Validation for the Number of Factors in Approximate Factor Models
Xianli Zeng, Yingcun Xia, Linjun Zhang
Determining the number of factors is essential to factor analysis. In this paper, we propose {an efficient cross validation (CV)} method to determine the number of factors in appro…
