研究发现:聊天机器人竞技场排名模型对相似大型语言模型失效

一篇新的arXiv论文《相似模型,失效的概率》探讨了聊天机器人竞技场用于对语言模型进行排名的Bradley-Terry模型的局限性。研究发现,该模型基于Luce选择公理,由于未能充分考虑高度相似模型之间投票的决定性,从而过度简化了排名。在超过180万张投票中,同一模型版本之间的投票比预测的决定性高出1.37倍,在同一代或同一实验室的模型中也观察到了类似效应。研究人员提出了一个更准确的四到六参数修正模型,该模型能更好地预测未包含的投票,特别是通过模拟平局,尽管它仅略微改变了整体排行榜的顺序。 AI

影响 凸显了当前大型语言模型评估方法的缺陷,可能导致更细致的排名系统。

    相似模型、破灭的赔率:Luce公理在聊天机器人竞技场中失效之处

    arXiv:2610.19095v1 Announce Type: new Abstract: Chatbot Arena ranks language models with the Bradley-Terry model, which gives each model one score and so assumes Luce's choice axiom. Choice theory predicts where this fails: near-copies are told apart more decisively than their sc…
