English(EN) Bilateral Trade Under Heavy-Tailed Valuations: Minimax Regret with Infinite Variance

新研究详细介绍了具有无限方差的双边贸易的最小最大遗憾

一篇新发表在arXiv上的研究论文介绍了一种用于重尾估值下双边贸易的新算法，特别解决了交易者估值具有无限方差的情况。所提出的方法扩展了现有的自界定性质，并利用截断均值估计来实现一种遗憾率，该遗憾率在经典的非参数率和线性率之间进行插值。这项工作为这个复杂的交易问题提供了精确的最小最大率表征。 AI

双边贸易在重尾估值下：具有无限方差的最小-最大遗憾

arXiv:2603.06851v2 Announce Type: replace Abstract: We study contextual bilateral trade under full feedback when, conditionally on the context, trader valuations have bounded density but infinite variance. We first extend the self-bounding property of Bachoc et al. (ICML 2025) fr…
