新的ReAlign框架通过奖励引导对齐改进生成式重排序

研究人员推出ReAlign,一个新颖的框架,旨在通过将列表式奖励模型与自回归生成器对齐来增强生成式重排序。该方法旨在通过直接将列表式信号纳入生成过程来改进排序列表的精炼,以最大化用户效用。ReAlign采用两阶段训练方法,包括监督预训练和奖励引导后训练,在广泛的离线实验中证明了其优于现有方法的性能。 AI

影响 这项研究可以通过改进排序列表的精炼以提高用户效用,从而带来更有效的搜索和推荐系统。

    Re-ranking refines the upstream ranked list to maximize listwise user utility. Existing two-stage generator-evaluator methods decouple list generation from list evaluation, leaving the generator without direct access to the listwise utility signal, while scoring-based one-stage m…
