机器学习同行评审中用于指数族估计的保序机制

研究问题
如何利用作者对多篇投稿的质量排序改善评审分数估计,并在什么效用条件下使作者有动机报告真实排序?
方法与思路
作者把保序机制扩展至指数族,使调整分数接近原分数且满足作者排序,并分析报告激励、估计误差及排序数据。
材料陈述的贡献
摘要称在凸可加效用下可激励如实排序,在真值总变差有界时接近极小极大最优,并用 ICML 排序数据展示估计收益。
阅读关注点
应核对指数族适用范围、效用与真实性条件、成对比较结论的逻辑范围,以及代理质量指标和近最优误差界。
阅读边界
所给版本为 arXiv 预印本,不能据此认定已同行评审或被期刊接收;代理质量并非已验证真值,摘要未说明收益数值。

原文摘要

In 2023, the International Conference on Machine Learning (ICML) required authors with multiple submissions to rank their submissions based on perceived quality. In this paper, we aim to employ these author-specified rankings to enhance peer review in machine learning and artificial intelligence conferences by extending the Isotonic Mechanism to exponential family distributions. This mechanism generates adjusted scores that closely align with the original scores while adhering to author-specified rankings. Despite its applicability to a broad spectrum of exponential family distributions, implementing this mechanism does not require knowledge of the specific distribution form. We demonstrate that an author is incentivized to provide accurate rankings when her utility takes the form of a convex additive function of the adjusted review scores. For a certain subclass of exponential family distributions, we prove that the author reports truthfully only if the question involves only pairwise comparisons between her submissions, thus indicating the optimality of ranking in truthful information elicitation. Moreover, we show that the adjusted scores improve dramatically the estimation accuracy compared to the original scores and achieve nearly minimax optimality when the ground-truth scores have bounded total variation. We conclude with a numerical analysis of the ICML 2023 ranking data, showing substantial estimation gains in approximating a proxy ground-truth quality of the papers using the Isotonic Mechanism.
